15. Pressure Measuring Point
There is a pressure test point within the MQM Quantometer as shown in figure 8. The pressure
tap is marked with “pm”. The pressure test point is designed for a connection of steel tubing
with a diameter of 6 mm. The steel tubing should be according DIN EN 10305-1. The pipe
connection or fitting should be in accordance to DIN 2353. It may only be used seamless
drawn stainless steel tubes according to DIN EN 10216-5:2014-03. Pipes not made of stainless
steel
or made out of non-metallic materials are not allowed.

16. Temperature Measuring Point
There is one temperature test point as shown in figure 9. The temperature tap is marked with
“tm”. The temperature tap is locked with a screw (G ¼”). In case of using the temperature tap
remove the plug screw and replace it by a temperature pocket with an integral thread of G ¼’’.
The temperature pocket is designed for a temperature sensor with a diameter of 6 mm.
Notice:
If the temperature tap of the Quantometer is not used the temperature measurement point
should be located 1-3 DN downstream of the meter.
