Product Data LIQUID FILLED GAUGES – OPEN FRONT STYLE Model 656 2-1/2" (63mm), 4" (100mm) and 6" (160mm) Open Front Stainless Steel Gauges DESCRIPTION The 656 Series are suitable for corrosive environments in chemical, petrochemical, refining, power, marine, and food and pharmaceutical processing applications. Liquid filled pressure gauges provide users with a number of advantages in certain measurement applications. They are ideally suited for uses on equipment where excessive vibration and pulsation are encountered, such as pumps, compressors, machine tools, etc. The liquid fill minimizes the effect of these severe environments, protects the gauge internals, and provides continuous lubrication on the mechanism, all adding up to extended service life. Liquid filling also provides greater protection of the gauge internals from corrosive atmospheres. All Model 656 gauges are made with seamless 316L SST Bourdon tubes, which reduces concerns about tube fatigue and stress corrosion cracking. AMETEK liquid filled gauges can be used with a variety of fill fluids including glycerin, mineral oil, and silicone oil. These gauges are available in 63mm (2-1/2"), 100mm (4"), and 160mm (6") sizes.

If gauges are to be used in such hazardous service, consult factory for other liquid filling and product alternatives. In order to correctly use these gauges, it is recommended that users of pressure gauges become familiar with American National Standard ASME B40.100 entitled “Pressure Gauges and Gauge Attachments.” This specification is available from the American Society of Mechanical Engineers, United Engineering Center, 345 East 47th Street, New York, NY 10017.
