The SERIES RMV Rate-Master® Flowmeters measure higher water flow rates with ±2% of full scale accuracy at an affordable price. Stocked models are fitted with 1" female NPT inlet and outlet; 3/4" and 1/2" sizes are also available. Install in line, supported by piping or flush panel mount with complete hardware package included.

Applications:

• Monitor coolant flow through ingot heaters, high-amp switchgear, resistance welders, heat exchangers, compressors, scrubbers.
• Monitor water consumption to different processes and operations for more efficient operation.
• Calculate required fill or drain times for tanks, water towers.

Options:

• ASF Option adds external pointer to indicate flow limit. Add -ASF suffix. Example: RMV-1-3-ASF.

Features:

• Rugged forged brass housing yields great compatibility and strength, allowing the unit to withstand system pressures to 1000 psig (68.9 bar)
• Shatter proof construction, unlike glass tube variable area flowmeters, yields long operation life

Location:
Select a location where the flowmeter can be easily read and where the temperature will not  exceed 200°F (93°C).
The mounting surface and piping to the flowmeter should be free from excessive vibration. If pulsing flow or vibration causes excessive pointer oscillation, contact factory for ways to provide additional dampening.

Piping:

• Inlet Piping: It is good practice to approach the flowmeter inlet with as few elbows, restrictions, and size changes as possible. Inlet pipe should be  as  close  to  the  flowmeter  connection  size  as  practical  to  avoid turbulence which can occur with drastic size changes. The length of inlet piping has little effect on normal pressure-fed flowmeters.
• Discharge Piping:  Piping on the discharge side should be at least as large as the flowmeter connection.
• Zero  Setting:  The  RMV  Rate-Master®flowmeter  is  calibrated  and zeroed in a specific (normally vertical) position at the factory. If the gage is used in any other position, it may be necessary to adjust the zero setting. Position changes can aversely affect accuracy. If re-zeroing is required, hold the brass case firmly with one hand and turn the grey bezel cover counterclockwise to remove. Next, lift off the plastic cover. Hold the 5/32 ̋ diameter brass knob below the pointer axis stationery  and  adjust  the  rectangular  brass  blade  between  axis  and knob.  Repeat adjustments as necessary until flowmeter reads exactly zero when held in its intended mounting position. To replace the cover, align the (2) 1/8 ̋ slots on the edge with matching 1/8 ̋ projections on the case adjacent to the pointer bumpers.  Install the bezel ring, hold cover in place with palm of hand and turn ring clockwise until tight.

Product Details:

The SERIES RMVII Rate-Master® Flowmeters consists of a machined brass meter body which is ideally suited for water flows with ±5% of full scale accuracy. Body design fits standard 4-1/2" mounting hole layouts per ANSI B40.1. Inlet and outlet threads are standard 3/4" female NPT.

Features:

• Unique construction fully isolates flowing media from gage front for leak-proof operation at pressures up to 3000 psig (206.7 bar)
• Target-type design combined with a damage resistant magnetic linkage, drive a pointer over easy-to-read litho scale
• Shatter proof construction, unlike glass tube variable area flowmeters, yields long operation life

Applications:

• Monitor coolant flow through ingot heaters, high-amp switchgear, resistance welders, heat exchangers, compressors, scrubbers
• Monitor water consumption to different processes and operations for more efficient operations
• Calculate required fill or drain times for tanks, water towers

Operation:
If flowing media is likely to be dirty, install a 50 micron filter upstream from the flowmeter. Once all connections are complete, introduce flow slowly to avoid possible damage. With liquid flow, it may be necessary to purge air from the system before reading staabilize. No lubrication or periodic servicing is required. Keep case exterior, including front cover, clean for best visibility.

Inlet Piping:
It is a good practice to approach the flowmeter with as few elbows, restrictions and size changes as possible. Inlet piping should be as close to the flowmeter connection size as possible to avoid turbulence which can occur with drastic size changes. The length of inlet piping has little effect on normal pressure fed flowmeters.
For vacuum service the inlet piping should be as short and open as possible to allow operation at or near atmospheric pressure, thus maintaining the accuracy of the device. Note that for vacuum service, any flow control valve must be installed on the discharge side of the flowmeter.

Outlet Piping:
Piping to the outlet should be at least as large as the inlet connection. For pressure fed flowmeters on air or gas service, the piping should be as large and short as possible. This is so pressure within the device will be at or near atmospheric for maximum accuracy. This is less important on water or liquid flowmeters since the flowing media is generally not compressible and therefore back pressure will not affect the calibration of the instrument.

Specification:
Wetted Materials:

• Body: 316 SS
• Spring: 302SS
• Range spring: 302 SS
• Magnet: PTFE-coated
• Orifice piston: Acetal
• Diaphragm: Fluoroelastomer.

Location:
Select a location where the flowmeter can be easily read and where the temperature   will   not   exceed   200°F   (93°C).   The   mounting   surface   and piping to the flowmeter should be free from excessive vibration. If pulsing flow or vibration causes excessive pointer oscillation, contact factory for ways to provide additional dampening.
Because the device operates through a magnetic coupling system, magnetic material near the flow block can affect accuracy. To minimize the effect of outside interference, keep magnetic materials at least 3 inches (7.6 cm) away from the unit.

Inlet Piping:
It is a good practice to have the inlet port of the flowmeter be as free of elbows, restrictions and size changes as possible. Inlet piping should be as close   to the flowmeter connection size as possible to avoid  possible turbulence, which can occur with drastic size changes. The length of the inlet piping has very little effect on normal pressure fed flowmeters.

Forvacuum service, the inlet piping should be as short and open as possible to allow operation at or near atmosphere   pressure, thus maintaining the accuracy of the device. Note that for vacuum service, any flow control valve must be installed on the discharge side of the flowmeter.

Outlet Piping:
Piping on the outlet port should be at least as large as the   flowmeter connection. For flowmeters fed by air or gas pressure, the piping should be as large and short as possible. This is so pressure within the device will be at or near atmosphereic for maximum accuracy. This is less important for water or liquid flowmeters since the flowing media is generally not compressible, and therefore back pressure will not affect the calibration of the instrument.

Product Details:

The Series OP Orifice Plate Flowmeter is a complete orifice plate flow metering package. It incorporates a stainless steel orifice plate with a unique holder or carrier ring containing metering taps and integral gaskets. It was designed for use wherever there is an application for a conventional flow orifice plate. It can also be used in place of other primary differential producers for efficiency and cost effectiveness. Installation is accomplished simply by slipping the unit between standard flanges (orifice flanges are not required). The Series OP is available in line sizes from 1/2" to 24" and can be used with compatible liquids and gases.

Features:

• Mounted with standard flanges
• Standard "corner tap" configuration
• Corrosion free material
• Simplified installation
• Built in metering taps (1/4" female NPT STD)
• Proven through a wide range of applications for accuracy and energy efficiency
• Assures long term reliability and accuracy
• Service : Compatible liquids and gases.
• Installation : Standard flange 125/150 rating.
• Pipe Requirements : General requirements 10 diameter upstream and 5 diameter downstream.

Applications:

• Fluid flow rates in building water lines
• Boiler feedwater
• Cooling water
• Combustion or compressed air
• Steam flow

Accuracy:

• The Series OP utilizes the corner tap proportions as defined in ISO 5167. While this code may not be referred to as International Standard until accepted by the ISO Council, the ASME Fluid Meters Research Committee has suggested that the dimensionless coefficient equation developed by the International Standards Organization (ISO) and presented in ISO 5167 is significantly better for the broad spectrum of flow measurement applications throughout process industries.
• The coefficient values used in the Series OP bore calculations represent the same confidence level assigned to the flange and radius taps widely accepted in fluid flow measurement.
• The accuracy assigned to the coefficient values is ±0.6% full scale flow for d/D (Beta) values 0.2 to 0.6 and ±0.7% for Beta values 0.7 to 0.75 (i.e. ß of 0.7 would have an uncertainty value of ±0.7% full scale flow).
• Accuracy of the differential signal produced by the Series OP equals or exceeds that of a properly manufactured and installed flange or radius tap orifice meter.

Mounting:
The orifice metering primary shall be suitable for installation between standard ANSI 125/150# flanges (any material) mounted on standard pipe (any material). The unit shall be "self centering" within the bolt circle of the flanges. No alignment of the orifice shall be necessary unless used with 300# or non-standard flange ratings. Drilling and or tapping of the main or flanges will not be allowed or required. The overall laying length shall be 1.25 ¿¿ including pre-attached ring type 1/8 ¿¿ thick Buna "N" Gaskets.

Pipe Requirements:
Upstream and downstream pipe requirements are contingent upon two factors: (a) Beta Ratio-ratio of the orifice bore to the pipe I.D. (d/D); (b) The type of fitting or disturbance upstream of the Series OP. For most applications, 10 pipe dia. upstream & 5 dia. downstream are sufficient. (5 pipe dia. up and 2 dia. down are acceptable for non-critical application.)

Mounting:
Location:
The flow tube should be installed with minimum 8 diameters of pipe run ahead and 5 diameters of pipe run after. This will ensure steady flow and accurate readings.

Installation:
The meter can be installed in a vertical or horizontal position. The Magnehelic ® gage must be positioned such that it is read in a horizontal orientation. The meter comes in a horizontal left to right configuration. If a vertical orientation is required remove the three mounting screws (1) from the back of the Magnehelic ® gage, reposition the gage within the bracket and re-tighten the screws.

The Magnehelic ® gage can be mounted remotely from the meter. If this is done make sure to keep the Magnehelic ® gage above the Venturi Flow Tube assembly. Condensation may collect in the tube if it is below the gage and cause false readings

The Venturi Flow Tube must be connected in the correct orientation. For example, in a left to right flow, the high pressure side which is on the left connects to the high pressure port on the Magnehelic ® gage. The low pressure side is on the right and connects to the low pressure port of the Magnehelic ® gage.

• Automatically starts auxiliary pumps and engines

 

Installation:
Carefully unpack switch and remove any packing material from lower housing. Trim the vane at the appropriate mark for the size of pipe being used.
Caution: Mechanical shock or vibration can cause permanent damage to the reed switch. Take care to avoid dropping the unit on hard surfaces or impacting the switch assembly.

Apply pipe thread sealant tape or pipe thread sealant to the 1/2 ¿¿ male NPT mounting threads and install switch in the system piping with the arrow on side pointing in the direction of flow.
Connect wiring in accordance with local electrical codes.

Inductive, capacitive and lamp loads can all create conditions harmful to the reed switch.

• Inductive loads can be caused by electromagnetic relays, electromagnetic solenoids and electromagnetic counters, all with inductive components as the circuit load.
• Capacitive loads can be caused by capacitors connected in series with or parallel to the reed switch.
• In a closed circuit the cable length (150 ft. or more) to the switch can introduce a capacitance Lamp loads can be caused by switching lamp filaments which have low cold resistance.

In addition to these causes, exceeding any of the maximum electrical ratings can lead to premature or immediate failure. This includes inrush and surge currents greater than the maximum switching current. Use caution when evaluating system loads and current. To accommodate these conditions, see diagrams on the reverse which depict possible solutions.

After installation, set the switch action to NO (normally open) or NC (normally closed). Normally closed contacts open and normally open contacts close when increasing flow actuates the reed switch. To change, loosen, but do not remove, the two screws on the top cap. Slide the reed switch assembly to expose the switch action selected. Tighten screws when adjustment is complete.

The SERIES TDFS Thermal Flow Switch uses impulse thermal dispersion measurement technique to indicate whether the flow rate is above or below a user set flow rate. It provides NO and NC NPN outputs and two LED, one green and one red for high and low set point indication.

Features:

• Better long term reliability and life expectancy than mechanical flow switches with no paddles or vanes to wear or break, no jams in the paddle movement, and no seals on movement assembly to wear or leak
• Not affected by empty pipe detection and avoids overheating by actively heating above the process temperature and then cooling down to process temperature
• Set point is easily field set by taping the included magnet on the set point target three times at the desired flow rate
• LED status indicators provide visual switch indication of set point
• Low pressure drop, only needs to be 10% into the flow (e.g. 1/8" for 3/4" schedule 40 pipe)

Product Details:

The SERIES MFS Magnetic Inductive Flow Sensor is a compact, low cost alternative to paddle wheel sensors. Unlike sensors with moving parts, the MFS can be applied in applications dealing with contaminated media. This series provides a reliable measuring technique, an obstruction free pipe cross-section, as well as a quick response time, making this series ideal for interference free operation. Any change in temperature, density, viscosity, concentration or electrical conductivity of the liquid, does not affect the output signal of this Magnetic Inductive Flow Sensor. This, in addition to its long-life cycle, makes this series perfect for accurate reversible gauging of volume flow of conductive liquids in closed piping.

Principles of Operation:
The measuring pipe is in a magnetic field. If an electrically conductive medium with a certain flow passes through the pipe, it passes at a right-angle to the magnetic field, creating a voltage which is proportional to the average flow velocity and picked up by two electrodes within the MFS. A frequency output signal is obtained that is proportional to the flow (analog output option available).

 

Features:

• Long life cycle with no moving parts to wear or break
• Can be applied in applications dealing with contaminated media with no mechanical component in the flow
• Obstruction free pipe cross-section yields low pressure drop
• Unaffected by change in temperature, density, viscosity or concentration

It is a compact and lightweight instrument incorporating the latest electronics and signal processing technologies, realizing high performance and easy operation. This device is capable of 20 hours continuous operation with its built-in battery. The PUF comes with an IP67 rated carrying case with molded foam inserts to hold and protect all equipment against dust and water. The screen offers easy to read text with a convenient backlight for visual comfort. The efficient layout of the function keys add to this unit's easy to use programming. The unit comes with RS232 and USB connections to allow for easy connection to any personal computer or printer.

Principles Of Operation:
Two sensors are placed on the exterior of the pipe, and each transmits an ultrasonic pulse through the pipe and fluid to the other. The velocity of the liquid flowing through the pipes causes the pulse to accelerate or decelerate. The difference in the transit times of the two pulses is used to calculate the flow rate. The use of transit time allows the flowmeter to be unaffected by pressure or temperature changes.
