5. Compatibility of connectors
The piping connector of Manostar switch MS65, MS65F, WO81, and WO70 are not compatible with each
other.Make sure to use the dedicated connectors of Manostar switch MS65, MS65F.
6. Caution of piping
a)
Prohibition of common piping
Piping each of pressure detectors and pressure
receiving instruments tube exclusively dedicated
for it, and do not connect the piping commonly
with the adjacent system as shown in the right
fi gure.
Common piping causes measurement error because
the pressure of each system interferes.
b)
Prevention of clogged piping due to drain
・ If drain remains within the line, it causes measurement error. Be
sure to install the pressure receiving instrument above the pressure
outlet port of the pressure detector and arrange the line so that the
drain water should not remain in the slack piping.
・ If the arrangement mentioned above in not possible, install a drain
tank within the line as shown in the right fi gure and clean it once in
a while.
・ After the cleaning of the tank, check that the air tightness is fully
kept.
c)
Measurement of high temperature gases
In the pressure measurement of high temperature gas, use the pressure detector (pitot tube) made of
the heat-proof metal (such as stainless steel), and connect it with the pressure receiving instrument
through a metal tube which is long enough to cool down the high temperature gas.
d) Errors caused by long distance piping
The speed of response is delayed when the product is used for remote monitoring.
In such application, the I.D. of the connection tube should be as large as possible.
The time constant is almost inversely proportional to the inner cross sectional area of the piping.
If the piping conditions of the high and low pressure side are signifi cantly different, the difference in the
piping resistance between high and low puressure side causes the difference in pressure transmission
time, and the measurement becomes inaccurate.
