3.2 Mechanical installation
Warning: Do not alter the adjustment nut at the back of the TVA flowmeter shaft, as
this will affect the flowmeters calibration.
Orientation
The TVA flowmeter can be installed in any orientation when used on saturated steam
applications and when the pressure is below 7 bar g (101 psi g), see Figures 7, 8 and 9.
When the pressure is above 7 bar g (101 psi g) or used on a superheated steam application
the TVA flowmeter must be installed in a horizontal pipe, with the electronics housing below
the body, see Figure 9.
Note:
The TVA flowmeter operates with flow in one direction only. It is not intended for use
with bi-directional flow. The TVA flowmeter is clearly marked with a direction of flow arrow.
Caution: If the electronic housing is
mounted at an angle of 45° (or more) 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.
