For general use wherever stem mounting is desirable and the pressure medium is non-corrosive to brass, phosphor bronze or beryllium copper. ir, oil, gas and water services are the most common applications. Generally used for hydraulic applications, such as presses, jacks and pumps, these specially designed 2-1/2 P500 heavy duty gauges can also withstand other rigorous pulsating and vibrating high pressure industrial applications. The ability of these gauges to withstand rugged service can be attributed to the unique GLSSTUF TM movement and to the high quality beryllium copper bourdon tube. GENERL PURPOSE GUGES/PRODUCTS 3

7 ir Volume Controls TYPE 300L TYPE 310WJ SHLLOW WELL OPERTION 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. ir 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. HOUSING: Die cast zinc, with 1-1/4 NPT male connection for tank installation, and 1/4 NPT female connection to accept a U.S. Gauge Model P500 pressure gauge, 1/4 NPT, LM connection. IR INLET VLVE: Schrader or Dill type valve is mounted in the hose connection. FLOT: Sturdy, plastic bulb, mounted on a solid brass rod. INTERNLS: 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. DEEP WELL OPERTION 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. s 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. HOUSING: Die cast zinc, with 1-1/4 NPT male connection for tank installation, and 1/4 NPT female connection to accept a U.S. Gauge Figure P500 pressure gauge, 1/4 NPT, LM connection. MIN VLVE: Brass stem with a neoprene seat, float actuated. RELIEF VLVE: Brass, spring loaded pressure actuated. Manually adjustable between 15 and 40 psi. Stock units preset at 25 psi. FLOT: Sturdy, plastic bulb, mounted on a solid brass rod. Water Level Measurement Gauges P503 and 566 SIZE: P503: 3-1/2, 4-1/2 ; 566: 4-1/2. CSE: Drawn steel, black corrosion-resistant paint. RING: Drawn steel, black corrosion-resistant paint. P503: friction fit; 566: slip with side screws. WINDOW: Flat glass. POINTER: luminum, black finish; 566: brass, black finish. P503 has red feet of water markings; 566 has a rotating dial. MOVEMENT: Brass. BOURDON TUBE: Phosphor bronze, soft soldered. CONNECTION: 1/4 NPT LM, brass. RNGES: P503: 0 to 100 psi/0 to 231 H 2 O; 566: H 2 O. CCURCY: ± 3-2-3%. Type P503 gauges are used for measuring head of water in an open tank, or the equivalent head in a pressurized tank. Type 566 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. U.S. Gauge ir 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. 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. SPECIL PPLICTION GUGES/PRODUCTS 7

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 medium being measured to escape from its container. Designed to withstand rugged conditions, this thermometer has an eccentrically mounted pointer actuated by a helical bi-metallic element enclosed in a metal shield. While normally used for domestic or commercial heating systems, this thermometer is rugged enough for many industrial applications.
