INSTALLATION
CONFIGURATION
The Orifice Flowmeter Assembly must be installed in the proper orientation
relative to the pipe and the fluid measured.
Gas Applications
Mount hardware upward to allow moisture to drain out and not fill the impulse
piping:
• Slope impulse piping at least one inch per foot (8 centimeters per
meter) downward from the transmitter toward the process connection.
Liquid Applications
Mount hardware downward to allow the escape of trapped vapor in the
impulse piping:
• Slope impulse piping at least one inch per foot (8 centimeters per
meter) upward from the transmitter toward the process connection.
• Vent all gas from the liquid piping legs.
• Prevent sediment deposits in the impulse piping.
• Keep the liquid head balanced on both legs of the impulse piping.
