Differential pressure transmitter with temperature / pressure compensation function EDR-N7C

We are proud to present the upgrades of the highly-regarded N6 series. Combining with the device that has the saturated vapor pressure compensation function (conventional device: EDR-N6B), it can perform saturated vapor pressure compensation and temperature / pressure compensation in just one equipment. Also, with an addition of 800 to the range code it has improved accuracy with regard to low flow range.

For settings / changes, version 1.30 and after of DCR intelligent communicator is needed.
