Coriolis Mass Flow Transmitter RHE07/08

Multifunction Coriolis Mass  Flow Transmitter Series

The RHE08 Coriolis Mass Flow Transmitter is designed for field mounting. With a weatherproof exterior, the RHE08 can be wall or panel-front mounted. The UV resistant display window will not crack, craze or cloud over time. Externally mounted buttons provide convenient operator access to all process variables and setup information. Cable entries are adaptable for flex, armoured cable or conduit and all terminations are accessible through a separate cover plate.
The RHE08 Coriolis Mass Flow Transmitter can be used with an RHM sensor in a hazardous area (RHE08 in safe area or in Zone 2). CSA certified versions of the RHE08 can be mounted in a Class 1, Div 2 area.
The RHE07 Coriolis Mass Flow Transmitter is designed to sit in a standard 19″ Eurocard style rack. The transmitter has two Eurocard connectors on the back to allow the unit to be plugged into an integrated rack system directly. For standalone applications, the RHE07 is easily adapted to panel mount and has a screw terminal adapter accessory to allow field wiring to be connected directly to the rear of the unit.

The RHE07 transmitter can be used with an RHM sensor in a hazardous area (RHE07 in safe area).CSA certified versions of the RHE07 must be mounted in a safe area.

RHE07/08 General Specifications

Coriolis Flow Transmitter RHE

Inside the measuring sensor, there are precision tubes that are energized by an electromagnetic drive system, which itself is fed by the transmitter, to vibrate at their natural frequencies. When a liquid or gas flows through the vibrating tubes, it is subjected to additional deflection due to the degree of inertia that is generated. This deflection is recorded electronically by two velocity sensors and a high-precision electronic time delta. This measured quantity is proportional to the mass flow rate.

A further conversion into physical units is done in a purely digital manner using a signal processor in the transmitter. At the same time, all of the appliance’s functions are constantly monitored. Should any disruptions occur, all of the errors that have occurred are immediately reported in the display.

The transmitter has a 4 to 20 mA analogue output with programmable span, which is proportional either to the measured mass flow rate or the temperature; it also has an impulse output that supplies mass-proportional impulses. All of the outputs and measuring functions can be verified at any time by the user by using the diagnostic mode in the appliance. The maintenance or new calibration intervals can be monitored via a run-time counter. For service or repair purposes, the transmitter and flow sensor can be replaced independently of each other.

This significantly reduces the costs of spare parts for the installed flow sensor/transmitter. During the factory calibration, the mass flow sensor can be calibrated independently of the transmitter. All sensor-specific calibration data can be programmed using magnetic switches located on the front panel. To achieve this, the instrument does not need to be opened. All of the relevant data is buffered in a non-volatile semiconductor device (EEPROM).

The RHEONIK mass flow meter consists of one of the RHM series flow sensors and one RHE series transmitter. The remote unit RHE 07/08 is for installation in a safe non-Ex area and is connected to the sensor via a single multi-conductor cable. Please note, that the types RHE 07/08 and all sensor articles are available in non Ex-versions (without Exnameplate). The RHE 11 (Ex d) may be installed and operated in hazardous Ex-areas (Zone 1 or 2). Ex-series sensors RHM (with Ex-Label) are, when connected with an Ex- Transmitter, made for installation inside hazardous areas (Ex-zone 0, 1 or 2). The transmitter RHE includes seven printed boards which can be replaced during servicing. The remote electronic unit consists of two bent measuring loops in the shape of an omega.
