2.6 Installation Procedures
If the Model 230 is supplied with an optional 3-Valve Manifold assembly, refer
to section 2.8, Optional 3-Valve Manifold Assembly Procedure, for further
installation procedures. If the Model 230 is not supplied with a Setra 3-Valve
manifold, the following installation procedure is recommended.
For differential pressure
measurements at high
line pressure (250 psig max.),
it is recommended that the
pressure sensor be installed
with a valve in each line, plus
a shunt valve across the high
and low (reference) pressure
ports, as shown.
2.7 BLEEDING THE PRESSURE PORTS
3 bleed screws are on the side of the unit (2 for low pressure port, 1 for high
pressure port). Install the transducer in its intended location and pressurize the
ports. Back off the first bleed screw mounted on the flat side of the sensor
body (2 turns max.) until liquid begins to flow out. After only bubble-free liquid
flows out, retighten the bleed screw. Repeat same procedure for the second set
of bleed screws located on the round section of the low pressure fitting.
