Impulse piping is the piping to be connected to the sensor’s process connection(s). For suggested flow and level
measurement piping arrangements, refer to Figures 4, 5, and 6. If additional information is needed, order UM340-
1, User’s Manual for XTC Transmitters, Series 340 Pressure Transmitter-Controllers. UM340-1 from either your
local Moore representative or the factory.
Note the following when planning and installing piping.
· Install impulse piping in accordance with ANSI Code B31.1.0.
· Make impulse piping length as short as possible to reduce frictional loss and temperature-induced pressure
variations. However, when using impulse lines on a high temperature process, locate the Model 348 far enoughaway from the heat source to keep it within temperature specifications [10°C (50ºF) per foot cooling to a
normal ambient is assumed for uninsulated impulse lines].
· For lines between the process and sensor, use impulse piping of 3/8" OD or larger to avoid friction effects
(causes lagging) and blockage.
· Use the least number of fittings and valves possible to minimize leakage problems. Teflon®
 tape is the
recommended thread sealant for process connections at the sensor.
· Valves used in pressure service should be either globe or gate type. Valves used in gas service should be of a
type that does not permit condensate to build up behind the valve.
· Install sediment chambers with drain valves to collect solids suspended in process liquids or moisture carried
with non-condensing gases.
· Install air chambers with vent valves at high point in piping to vent gas entrained in process liquid.
· Remote diaphragm seals can be used to keep corrosive liquid or gas from the sensor’s pressure inlets and
isolation diaphragm [see ITT Conoflow Diaphragm Seals (PI34-6) for details].
Alternatively, use sealing fluid to isolate the process from the sensor. Sealing fluid must be of greater density
than process fluid and non-miscible.
· For a sensor located above the process, slope piping from the FIELDPAC at least 1 inch/foot (83 mm/M) down
toward process. For a sensor below the process, slope piping at least 1 inch/foot (83 mm/M) up to process.
· Protect pressure lines (by shielding if necessary) from objects or equipment that may bend or kink the line
causing fluid flow restriction.
· Protect the pressure lines from extreme temperature ranges. Lines should be protected from freezing by
installing a heat trace.
