NOTE
The meter is operated with separately approved pair of Pt 100 or Pt 500 temperature
sensors. The type of sensor to be used is printed at the front of the calculator.
Ensure that the approved temperature range of the temperature sensors is the same
as the temperature range of the calculator! A temperature sensor is normally
installed in the flow sensor for nominal sizes from q
p
0.6 m³/h to 2.5 m³/h. Both
temperature sensors are installed free for nominal sizes
≥
q
p
3.5 m³/h.
Handle the temperature sensors carefully!
The sensor cables are fitted with coloured type labels:
