SPECIAL APPLICATION GAUGES
How to Order
1. Basic Model Number—(example: P500, P733, etc.).
2. Dial Size—found under the SPECIFICATIONS section
for each gauge. (example: 2-1/2”, 3-1/2”, etc.).
3. Pressure Range—from the various ranges shown in
the SPECIFICATIONS section on each product. The
graduation details for each of the different ranges is
shown on page 12. (example: 0 to 30”Hg VAC, 0 to
100 psi, etc.).
4. Connection Size and Location—This data is also
listed under SPECIFICATIONS section and cross
referenced with the general dimensional data below.
See the abbreviations at left for describing connection
location. (example: 1/4” CBM, 1/8” LM, etc.).

Once you have completely specified the instrument you need
(example: P500 General Purpose Gauge, 2” dial, 0 to 60 psi, 1/4”
ANPT LM (low male); simply call your local U.S. Gauge
distributor and they will give you price and delivery information.
If you need assistance in specifying the proper instrument for
your applications, simply call your distributor. They are an
instrument specialist, trained to help you find the appropriate
product for your pressure measurement problems.

cases, the model number of the gauge specifies the
bourdon tube/connection material. However, if you
would like to specify a gauge with special materials
you must specify each.

For general use wherever
stem mounting is desirable
and the pressure medium is
non-corrosive to brass,
phosphor bronze or beryllium
copper. Air, oil, gas and water
services are the most
common applications.

specially designed 2-1/2”
P500 heavy duty gauges can
also withstand other rigorous
pulsating and vibrating high

applications. The ability of
these gauges to withstand
rugged service can be
attributed to the unique
GLASSTUFTM movement and
to the high quality beryllium
copper bourdon tube.

Air Volume Controls
TYPE 300L
TYPE 310WJ
When the water level is high, the float, secured to a
float rod extending through a flexible dividing wall,
opens an air inlet valve in the body of the control. The
air inlet valve is connected through 48” long
polyethylene tubing to a snifter valve on the pump and
has no direct connection into the tank. The snifter
valve admits air into the pump but prevents the water
in the pump from escaping back through it. Air is
drawn into the pump through the air inlet valve,
connecting tubing and snifter valve and carried out
with the water into the tank. This operation continues
until the volume of air increases to the proper amount,
at which time the float closes the air inlet valve,
shutting off the supply of air to the pump. The
optimum relationship between the volume of air and
water in the tank is thus maintained.
DEEP WELL OPERATION
When there is an excess of air and the water level is
low, the float opens the main valve of the control,
permitting air to be vented to a chamber within the
control. This chamber contains an adjustable pressure
relief valve which exhausts the excess air to the
atmosphere, providing the pressure in the tank is
higher than the relief valve setting. As the float rises
with the increase in water level the main valve closes,
trapping the remaining volume of air in the tank. The
optimum relationship between the volume of air and
water in the tank is thus maintained.

connection for tank installation, and 1/4” ANPT female
connection to accept a U.S. Gauge Model P500
pressure gauge, 1/4” ANPT, LM connection.
AIR INLET VALVE: Schrader or Dill type valve is

rod.
INTERNALS: A flexible, molded neoprene plug of
unique design acts as both dividing wall and fulcrum
through which float action is transmitted to the air inlet
valve.

Water Level Measurement Gauges
PA503 and A566
SPECIFICATIONS
SIZE: PA503: 3-1/2”, 4-1/2”; A566: 4-1/2”.
RING: Drawn steel, black corrosion-resistant paint.
PA503: friction fit; A566: slip with side screws.
WINDOW: Flat glass.
POINTER: Aluminum, black finish; A566: brass, black
finish.
PA503 has red feet of water markings; A566 has a
rotating dial.
MOVEMENT: Brass.
BOURDON TUBE: Phosphor bronze, soft soldered.
CONNECTION: 1/4” ANPT LM, brass.
RANGES: PA503: 0 to 100 psi/0 to 231’ H2O;
A566: 0-390’ H2O.
ACCURACY: ± 3-2-3%.
Type PA503 gauges are used for measuring
head of water in an open tank, or the
equivalent head in a pressurized tank. Type
A566 is used to indicate depth of water in a
well. Gauge and air line to well bottom are
charged with air. The pressure required to
permit air to escape from the end of the air line
is a measure of the head of water above the
end of the air line. The length of air line may be
set on the adjustable dial to permit reading
water level in feet below the ground surface.
Too much air in the pressure
tank will permit large bubbles
to be carried into the piping
system. This causes a
disagreeable noise and
sputtering at the faucets.
It is the function of U.S.
Gauge air volume controls to
maintain the correct
relationship between the
volume of air and the quantity
of water in the pressure tank.
SPECIAL APPLICATION GAUGES/PRODUCTS
SHALLOW WELL OPERATION
U.S. Gauge Air Volume
Controls are designed for
domestic water supply
systems which deliver a
quantity of air to the pressure
tank with each cycle of pump
operation. Insufficient air in
the pressure tank causes
frequent operation of the
pump.

Glass Tube Thermometers
T571 and T572
SPECIFICATIONS
The U.S. Gauge 5” industrial thermometer is a
small, compact instrument of sturdy steel
construction. It combines the advantages of
easy readability, small size and adaptability to a
variety of installations requiring an economical
thermometer. Careful consideration must be
given to the material of the bulb shield. Failure
of the bulb shield by corrosion will allow the

enamel. Case fits directly on the metal bulb shield
forming an integral assembly.
INDICATION: Magnifying glass tube filled with red
liquid. Black temperature scale printed on white case
shell.
BULB SHIELD: Steel zinc plated or brass.
T571, Low connection only, scale may be oriented by
rotation of the bulb within its shield. Insertion length
is 1-3/8”.
