Installation RHM XX
Wiring
RHM XX - RHE XX
Bubble Free
filling of RHM XX
Zeroing
procedure
Start with
measurement
This is a short version, please read also our Field Manual
- proper support at both sides of
the sensor required - see manual
- avoid installation at locations with
high levels of vibrations or strong
electrical fields
- wiring of RHE XX according to
our manual - attention :
digital outputs optocoupler ( passive )
connect external power supply with
pull-up resistor. Observe maximal
allowed power supply
- power on and allow RHE XX 30 min. warming-up.
- fill the sensor completely and bubble free with medium,
flush sensor RHM through with relatively high flowrate
for at least 15 minutes
- attention : avoid any temperature shock
( read manual in detail )
- shut off the flow with a ball valve properly
For small meter sizes ( RHM 015 - 03 )
two valves are recommended
- press the zero button and watch the
indication ( see manual )
- open valves, start pump etc. - meter is ready for measurement
- if the installation conditions are changed significantly, please
perform a new "zeroing"

- remove transport fixation bold
( if applicable ) and re-seal the
housing before operating
- at least one ball valve recommended
for zeroing
- Check : No error message / indication for transmitter ?
- Check : No error message / indication for transmitter ?
- Check : stable indication ( zero flow ) without error indication available ?
