Measuring points
13.1
Pressure measuring point
There is a pressure measuring point (1) on the housing of the MQMe Quantometer for
measuring the reference pressure. It is designed for a straight steel tube fitting according
to DIN 2353 with a diameter of 6 mm.
The material used for the tube should be selected according to DIN EN 10305-1. Only
seamless tubes made out of stainless steel according to DIN EN 10216-5:2014-03 may be
used. Tubes made out of non-stainless steel or non-metallic materials are not permitted.

Temperature measuring point
There is a temperature measuring point (2) on the housing of the MQMe Quantometer for
measuring the gas temperature. The temperature pick-up is closed off with a safety screw
(G ¼”). If you intend to use the temperature measuring point, remove the safety screw and
replace it with a temperature pocket with a G ¼’’ thread. The temperature pocket should
be designed for use with temperature sensors with a diameter of 6 mm.
Note:
If the temperature measuring point on the meter is not used, the temperature
should be measured in the pipeline 1–3 DN downstream of the MQMe Quantometer.
