3.3 Fitting the pressure sensor for superheated steam applications
To operate the TVA flowmeter on superheated steam the pressure sensor must be installed
upstream of the actual flowmeter. This is to give full density compensation and allow the
amount of superheat to be calculated.
A ¼" NPSM boss will be required on the pipe for the connection of the 'U' syphon and pressure
sensor. It should be sited as close to the upstream flange as practicably possible (see Figure
19, and take into account dimension 'X' in Section 2.8).
Note: The TVA must only be used for superheated steam application, when the pipe is in a
horizontal plane.
