3.5.2 Installing the pressure sensor
A three-way test valve is normally fitted to be able to test the pressure sensor also when
installed.
▸
Before installing a pressure sensor, check if there is a G 1/4" or NPT 1/4" thread on the
meter body.
▸
The thread type is marked on the meter body:
Fig. 30 Marking on meter body
▸
When the meter body has an NPT 1/4“ thread, screw in the adapter from NPT 1/4“ to G
1/4“ (Part No. 2075562) before using the accessory parts available from SICK.
Variant 1: Installation with test valve BDA04 (up to -20 °C dynamic, up to -30 °C static)
1 Remove the dummy plug on the pressure measuring port marked “P
m
”.
2 When the meter body has an NPT 1/4“ thread, first screw in the adapter from NPT 1/4“
to G 1/4“ (Part No. 2075562).
3 Fit the test valve BDA04.
Pay attention to the alignment of the connection for the pressure sensor.
NOTICE: Fitting information
It is recommended to connect the pressure sensor with the three-way test
valve or with the FLOWSIC500 so that there is a downward slope from the
pressure sensor to the connection point and from the three-way test valve to
the FLOWSIC500.
Thread G 1/4“ Thread 1/4“ NPT
NOTICE:
The thread on the meter body is damaged when a wrong thread type is screwed
in.
Observe the marking on the meter body!
For details on installation with test valve BDA04, see manufacturer Operating
Instructions.
