flow transmitter 2-wire


Our new two-wire, loop-powered differential pressure and flow transmitters offer users more flexibility. Because there is no need to bring external power to the transmitter unit, installation time and cost are reduced.

Our differential pressure and flow transmitters are offered on:

Our differential pressure and flow transmitters are available with a 4-20 mA (two wire) output for loop-powered installations, which offers the user the most savings in installation. A 0-5 VDC (three or four wire) output also is available as standard. The input voltage is 9-35 VDC.


These differential pressure and flow transmitters are built on the same pressure body as our high line pressure (to 5,000 psi) gauges and switches. Select from many different pressure ranges (0-5" H2O to 0-1000 psid) and flow ranges (0-1 GPM to 0-10 GPM).

Built for difficult industrial applications, a weatherproof enclosure protects the transmitter electronics with Class 1, Div. 1&2, Nema 4X and IP65 ratings. A 7/8" (22 mm) knockout is standard for 1/2" conduit connections.
