6.6 Ambient Temperature
Given in Fig. . is the allowable process fluid
temperature relative to the ambient temperature.
Ensure that the ambient temperature is held
within the rating.
If there is a possibility that the ambient
temperature exceeds the allowable limit,
the following measures should be taken into
consideration.
●
Avoid exposure to the direct rays of the sun.
●
Separate from the piping and equipment of
elevated temperatures or provide a heat shield.
●
Thermally insulate the preamplifier (in a low
temperature environment).
6.7 Partially Filled Pipe
When making measurement of a liquid, make sure the piping remains full of fluid and contains no trapped
air or gases. In applications where the existing piping conditions potentially cause a partially filled
pipeline, a purge valve should be provided.
6.8 Working Stage and Hoist (hottap type)
To facilitate hottap type DELTA meter inspection and maintenance, we recommend that a working stage
and a hoisting device are provided.
