Figure 3-5: Location of pressure and temperature transmitters
1 Install pressure transmitters on body of flowmeter at Pr point
2 Install temperature transmitter at 2...5 DN downstream of flowmeter
3 Install temperature transmitter under 45 degrees
4 Install temperature transmitter with an insertion depth between 0.1 and 0.33 of nominal pipe diameter.
INFORMATION!
• See ISO 17089 for further details.
• Use a PT 100 element with thermowell and transmitter as temperature transmitter.
Preferably use tapered thermowells to avoid vibrations.
• Connect the pressure transmitter to the Pr-point in the meter body using an intermediate
isolation valve and/or valve manifold.
CAUTION!
Either use a suitable blind plug or blind flange (and sealing as required) to blind the pressure
port, or a sense line should be connected in an appropriate way.
A sense line should be properly supported to avoid vibrations and to prevent the weight of the
sense line to apply a load on the connection at the pressure port.
