6 Service and Maintenance
6.1 Maintenance and Calibration
RHE2X mass flow transmitters and their associated RHM flow sensor do not require any regular
maintenance.
Under normal circumstances, RHE2X transmitters and their associated RHM flow sensor should
not require flow calibration. If flow calibration is required, either as a one off check or at
prescribed intervals to meet statutory or operational requirements, it can be carried out in one
of two ways:
1) In the field calibration against reference meter or prover
2) At a calibration laboratory
Local regulations or contractual/operational requirements will determine the type and interval
of such calibrations. Refer to the RHE2X Desktop Reference for full details on calibrating flow
meters using RHE2X transmitters.
Regular checks of the zero point calibration according to point 6 of section 2 and section 4.3 are
recommended to ensure a consistent measurement accuracy within the allowed deviations.
Density measurement in a RHE2X transmitter can be calibrated in the field. Please refer to the
relevant section in the RHE2X Desktop Reference for instructions.
6.2 Troubleshooting
Each status window shows a code e.g. ‘0x00000000’. By pressing the ENTER button, the cursor
walks through this code from right to left. The respective error or warning bit is explained at the
bottom of the display.
For detailed assistance, please refer to the troubleshooting section (Chapter 6) of the RHE2x
Desktop Reference. This chapter contains comprehensive information on understanding and
troubleshooting errors, warnings and connection issues with the flow meter.
The RHECom software can also be used to read out error codes, please refer to the RHECom quick
guide.
