Rheonik RHE42 Coriolis Mass Flow Transmitter for Field Mount



 RHE42 Rheonik Corioliss Mass Flow Display for Field Mount is available with a range of firmware options, including Assurance Factor diagnostics to provide an optimal flow measurement solution.

General Information

Connectivity includes a full suite of communications buses including Foundation Fieldbus and Modbus TCP/IP. The RHE42 is a well specified transmitter relevant for large scale plant and project opportunities.

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. RHE42 include batch and PID controller that make suitable for filling, batching, mixed and blending.

Program Packages and Features

The RHE42 is available with six different programming packages, each with specific features and
functions suited to typical user applications

Mass Flow Measurement Package (Part Number Code SO)

The RHE42 Mass Flow Measurement package provides all the basic measurement functions and
features for accurate mass flow measurement:

Direct Mass Flow Measurement

Mass flow is calculated using the Coriolis principle to provide a high accuracy Mass Flow
measurement of the fluid or gas flowing through an Omega Tube Coriolis sensor.

Temperature Measurement

Each Omega Tube Coriolis sensor provides a temperature measurement from built in sensors.

Density and Volumetric Flow Functions

Density and volumetric flow rate can be calculated, displayed and output from a transmitter by initiating one of several options for indirect density measurement:

  1. Fix or Norm Density value entry. A fix or Norm Density value is entered into the transmitter either through the keypad or via Modbus. This value is used to calculate a volumetric flow rate in addition to the live mass flow measurement. The density value could be updated as needed; via Modbus continuously if wanted. This particular function is often used to display a gas flow in normalized or standard gas volume units such as Nm³/h or SCF/h.
  2. Calculated density based upon temperature. A flowing density value is calculated based upon a reference density value, a change per unit temperature coefficient and measured tube temperature in the sensor. Based upon the tube temperature, the reference value is modified with the entered change coefficient to generate a calculated density value. This calculated density value can be used to provide a volumetric flow rate of the fluid in the sensor
