FlowTemp® M  is a very robust and high quality instrument for adjusting and optimizing tankless water heater.


  • Easy, fast determination of the temperature and water volume at water taps
  • Selection of measuring range for the volume flow by means of a disc with different holes

Application example: With a specified capacity of a tankless water heater and fluctuating water pressure, the flow rate may no longer be correct. The flow temperature can be measured simultaneously with the flow rate. This allows optimising the tankless water heater adjustments.
The adjustment options enable settings tuned to the individual tankless water heater. The clear scale ensures easy and precise readings.
