3.3.2 Installation in a pocket

In case of new installations, MID heat meter or temperature sensors for
nominal sizes DN25 or smaller must only be installed directly immersed.
The objective of a symmetrical measure set-up with higher measuring
accuracy is thus supported.

3.4 Installing the integrator

Pay attention to sufficient distance between integrator and pos-
sible electromagnetic sources of interference (switches, electric
motors, fluorescent lamp, etc.) during installation.
At the flow sensor (see fig. VI-A)
ƒ
Installation at medium temperature < 90°C and at T
With spacer (see fig. VI-B)
ƒ
Installation at medium temperature > 90°C and at T

3.5 Functional testing

After installation of the meter, putting into operation and functional test-
ing can be performed.
Proceed as follows:
ƒ
Open the stop valves
ƒ
Check system for tightness
ƒ
Bleed the system till the flow indication is stable. Adjust the system by
means of the flow indication
ƒ
After a short while the message "E - 7" disappears in the display.
ƒ
Press the push button next to the display and check the displays for
temperature and flow for plausibility.
ƒ
Attach tampering protection at the integrator and the temperature
sensors.
ƒ
Read and note meter data for energy, volume and serial number.
