Measured values
How accurately is the heat quantity determined?
The heat quantity is determined with a level of accuracy of +/-10%. The calculation is based on the recorded volume flow and the recorded delta of the fluid temperature.
How accurately is the cooling quantity determined?
The cooling quantity is determined with a level of accuracy of +/-25%. The calculation is based on the recorded volume flow and the recorded delta of the fluid temperature.
How accurately is the volume flow measured?
The volume flow is measured with a level of accuracy of +/-5%. In the partial load range, the deviation is up to +/-3% of QMax. (valid for heating water without additives). The level of accuracy decreases when using a water-glycol mixture.
Is the viscosity of the fluid taken into account when measuring the volume flow?
No. The viscosity of water is always assumed. These parameters cannot be changed either.
What sensors are integrated in the pump?
The pump only has one integrated temperature sensor. It is a digital temperature sensor. The fluid temperature sensor communicates via CAN bus to the electronic module.
Is the temperature sensor available as a spare part?
Yes, the temperature sensor is available as a spare part.
