Rheonik RHE42 Ex de Field Mount Flow Transmitter

Description

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.

Brand

Rheonik

With highly accurate measurement performance and extreme capabilities, Rheonik meters are a natural choice for many applications and quickly provide payback through improved product quality and greatly reduced maintenance. Whether used for transfer, batching, process feed or control, Rheonik meters can provide online flow and density measurement.

Since our start in 1984 we are one of the innovation leading manufacturers worldwide of coriolis mass flowmeters in precision, function and design – and we want to deliver more.
