Yokogawa EJA115

Yokogawa EJA115 Low Flow Transmitter Transmitter with 4–20mA HART protocol  with LCD  display

The model EJA115 Low Flow Transmitter is a flowmeter comprised of a differential pressure transmitter 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. The orifice is available in six types with a bore ranging from 0.508 mm to 6.350 mm. The combination of the bore selection with the differential pressure measurement span
variation of the differential pressure transmitter enables a wide range of very small flow measurement.
The model EJA115 also features remote setup and monitoring through communications with the model BT200/100 BRAIN TERMINAL, CENTUM CS/XL system etc.
