3. Installation
Note: Before actioning any installation observe the 'Safety information' in Section 1.
To meet its specified accuracy and performance it is essential that the following installation
guidelines are followed carefully. For steam applications sound steam engineering practices
should be followed, including the use of separators. The installation must conform to all
relevant construction and electrical codes.

A bypass line will enable safe removal of the TVA owmeter for maintenance or calibration.
Closing valves V1 and V2 and opening valve V3 will allow the T VA owmeter to be isolated
for re-zeroing (temperature to be <20 °C).

CAUTION:
If the electronic housing is mounted
at an angle of more than 45° from the
vertically downward position the PMO
(maximum operating pressure) must
be limited to 7 bar g (101 psi g) and
saturated steam applications only.
The electronic housing must be
mounted vertically downward for all
superheated applications.
