Safety notes for commissioning with differential pressure and flow rate

WARNING
Incorrect or improper operation
If the lock screws are missing or are not sufficiently tight, and/or if the valves are operated incorrectly or improperly, it could
lead to serious physical injuries or considerable damage to property.
Measure
● Take care that the locking screw and/or the vent valve are screwed in and tightened.
● Ensure that the valves are operated correctly and properly.
WARNING
Hot mediums
In the case of hot mediums, the individual operational steps should be carried out one after the other. Otherwise, it could
lead to excessive heating, thus causing damage to the valves and the transmitter.
