Signal Tube Installation
The tubing between the tank downpipe and indicator. Tubing
may be copper, nylon or polyo of the appropriate diameter
as recommended to convey the air ow to the downpipe and
resulting pressure back to the indicator.
D-1. Route tubing to avoid sharp bends and minimize exposure
to damage or high trafc areas. Recommended minimum
tubing diameters –
1/4” O.D. for distances up to 125 feet/38 m
3/8” O.D. for distances up to 550 feet/170 m
7/16” O.D. for distances greater than above
D-2. Install tube tting and connect signal tubing at indicator.
Tubing must be leak-tight for its entire run. Do not tee into
the signal tube for any equipement that consumes air.
Compressed Air Supply
Compressed air supply must be clean, dry and oil-free to ensure trouble free operation. Under normal operating conditions,
supply pressure should be 55-60 psig (380-420 kPa).
E-1. Install supply line at the Compressed Air Inlet connection
of the indicator.
E-2. Adjust the rotameter control so that the small internal oat
rests between the horizontal marks.
