Yokogawa EJA115E Low Flow Pressure Transmitter

Yokogawa EJA115E -DH Low Flow Pressure Transmitter

The low flow transmitter EJA115E is a differential
pressure transmitter assembled with an integral
orifice and excellent for very low flow measurement.
It outputs a 4 to 20 mA DC signal corresponding to
the measured flow.
