Microsensor MDM7000 Operation Manual page 20

For correct installation, it is recommended to follow:
The vent tube shall be kept as short as possible and avoid

sharp bends.
The slope of the vent tube shall not be less than 1:12 to

prevent sedimentation.
Before connecting to the transmitter, the vent tube must be

purged with compressed air. It is better to flush the vent tube
with the process medium.
If the medium is liquid, the vent tube shall be thoroughly

vented.
The layout of the vent tube shall allow for bubbles in the

measured liquid or condensate in the measured gas to flow
back into the process pipeline.
Ensure that the high and low-pressure side connections of

the vent tube are correct, secure, and free of any leaks.
Prior to the pressure process connection, confirm that the

relevant pipeline is clear and the construction components
are sufficiently robust.
When making the pressure process connection, confirm that

the relevant valves are closed.
After the connection is completed, confirm the good sealing

of the connected parts. Appropriate safety measures shall be
taken when venting or draining is necessary.
Avoid personal injury and property damage caused by high

pressure or corrosive medium.
