GAUGE SPECIFICATIONS
The armored design of the gauge offers maximum protection
for the sight tube from mechanical impact. Three sides of the
gauge are protected with a metal frame, while the face of the
gauge is protected with an impact resistant polycarbonate
shield. This shield can be custom calibrated to read tank
volume or any other desired calibration. Please see page 12 for
standard shield calibration options. A wide variety of wetted
materials and seals are available to ensure compatibility
with whatever uid is being used. For mounting purposes, a
mounting lug is welded to the back of the gauge.
The LG1-T-M50 has 1/2” MNPT x 3/8” FNPT threaded
process connections. 1/2” to 2” anged process connections
are also available. The standard sight tube is 5/8” O.D. glass.
Other sight tube options are also available upon request.
SPECIAL GAUGE APPLICATION - CHEMICAL
INJECTION SYSTEMS
Series LG1-T gauges are often used to calibrate chemical
injection systems. The injection rate of a chemical metering
pump is checked by closing a valve between the gauge and
the chemical storage tank and observing the change in uid
height in one minute. Using the rate scale on the front of the
polycarbonate shield, count the number of marks the uid
level passed during the one minute test period. This will give
you the actual chemical pump rate. If the rate is not the one
desired, make an adjustment to the chemical pump feed rate,
and conduct as many one minute tests as is necessary to set
the chemical pump to the rate desired. If a higher pump rate
is required, the test period can be shortened to 30 seconds
or 15 seconds.
LG1-T-M10 gauge are tted with 1” MNPT process connections
(anged process connections are also available). The standard
sight tube is 1” O.D. glass, which makes it ideal for viscous
liquids.
