RHE 42
Ex c Field Mount
With its advanced digital signal processing capability and in conjunction with our sensors, the RHE 42 can achieve an ultimate mass flow measurement uncertainty of 0.05 %, making it ideal for both filling and bottling or any kind of high accuracy/reliability plant flow or density measurement. Connectivity includes a full suite of communications buses including Foundation Fieldbus and Modbus TCP/IP. The RHE 42 is a well specified transmitter relevant for large scale plant and project opportunities.
