Danger
Protect the turbine meter from damage caused by high pressure changes
fluctuations in the flow, e.g. if the downstream pipeline system is filled or
blown off.
Danger
Welding on the line must only take place at a safe distance from the meter.
Extreme temperatures in the line near the meter can cause permanent dam-
age to the meter.
Danger
Establish all electrical connections between meters and amplifiers or flow
computers as specified in the installation manual. Ensure that the connec-
tions are intrinsically safe.
Caution
Liquids remaining in the line after hydrostatic testing can damage internal
parts of the meter.
If hydrostatic testing is not possible, the turbine meter must be replaced with
a pipe section. Ensure that there is no liquid remaining in the line above the
meter after the hydrostatic testing.

Threshold values
The following threshold values are recommended for maximum durability and the
highest measuring accuracy:
