5. Installing Impulse Piping
5.1
Impulse Piping Installation Precautions
The impulse piping that connects the process outputs to the XS530 must
convey the process pressure accurately. If, for example, gas collects in a
liquid filled impulse line, or the drain for a gas-filled impulse line becomes
plugged, it will not convey the pressure accurately. Since this will cause errors
in the measurement output, select the proper piping method for the process
fluid (gas, liquid, or steam). Pay careful attention to the following points when
routing the impulse piping and connecting the impulse piping to XS530.
5.1.1
Routing the Impulse Piping
(1) Process Pressure Tap Angles
If condensate, gas, sediment or other extraneous material in the process
piping gets into the impulse piping, pressure measurement errors may
result. To prevent such problems, the process pressure taps must
be angled as shown in figure 5-1 according to the kind of fluid being
measured.
NOTE
• If the process fluid is a gas, the taps must be vertical or within 45° either
side of vertical.
• If the process fluid is a liquid, the taps must be horizontal or below
horizontal, but not more than 45° below horizontal.
• If the process fluid is steam or other condensing vapor, the taps
must be horizontal or above horizontal, but not more than 45° above
