Flow Meter Transmitters for Liquids and Gases
Lyrica back order Our 4-20 mA Transmitters (option W2 and W3) are now CSA Approved for Hazardous Locations Ex ia IIC: Class I, Zone 0
The Flo-Gage can be fitted with a 4 wire transmitter to provide a 4-20mA (linear) output signal (Option W), 0-1000 Hz frequency outputs for remote totalization (Option Y), high/low relays for signaling flow conditions (Option X) or Option Z combines option W, X and Y in one unit. Our 2 wire loop powered 4-20mA (square root) output signal (Option W2 or W3) with either an indicating or non-indicating transmitter. Our flow transmitters for liquids and gases are available in threaded and flanged connection. 24Vdc power supply required (PS-24).
The RCM flow meter transmitters offer an economical single package solution includes sensor and transmitter:
- Differential Pressure measuring principle avoids problems associated with sticking floats and plugging passages.
- Solid state strain gauge senses differential pressure directly
- Low maintenance design with no moving parts.
- Designed for use with computer control systems or remote readouts
- Signal is proportional to flow rate squared (r2). (Square root extraction is required in the receiving device.)
- Intrinsic safety option for Class I Div. I, Groups A,B,C,D; Class II Div 1, Groups E,F,G; EExia IIc T4 (CSA and Cenelec approvals pending).

|The W option provides a 4-20 mA dc output for interfacing with remote indicators, controllers, computers and alarms. Option W uses a solid state sensor (Hall Effect) to detect the position of the pointer level mechanism. Low flow cutoff drives the output to 4 mA when flow drops below approximately 30% of full scale. Output is linear with flow rate.|

|Options W2 and W3 use a solid state strain-gauge to sense the differential pressure directly. Option W2 includes a mechanical flow indicator. Option W3 does not. Conditions which could cause the mechanical movement zero to shift will not affect the output from this transmitter. This transmitter provides improved rangeability at low flow rate and accordingly, does not include a low flow cutoff. Output is proportional to flow rate squared (r2). Square root extraction is required in the receiving device.|
|2 WIRE DIGITAL DISPLAY - RW3|
|The digital display flow meter is a 2 wire loop powered 4-20mA DC indicator that displays a flow rate and total. On-screen engineering units are easily configured. Password protection and 16 bit A/D resolution. A New built in wet/wet differential pressure sensor is protected by an isolated stainless steel diaphragm and provides a 4-20mA DC signal to the display. The enclosure is IP67 / NEMA 4X rated which further enhances this models capability. Available in threaded or flanged connection and bronze or stainless steel construction.|
|REMOTE DIGITAL DISPLAY - RD-1|
|The digital display can be connected as a remote display (option DR-1) to our 4-wire transmitter output option W (4-20mA linear output signal), 2-wire loop powered transmitter option W2 or W3 (4-20mA loop powered signal) output is proportional to flow rate squared or our 2-wire loop powered transmitter option RW3 which is self-contained and complete.|
