Supported Applications
The Dwyer Series LPG3 Low Pressure Gauges are designed for the measurement of low pressures in compatible gases and liquids. The series utilizes an elastic element that expands and contracts with very small changes in pressure to achieve ASME Grade 1A accuracy. Documented applications include air flow indicators, liquid level indicators, and draft gages.
Operating Conditions & Performance
The Series LPG3 operates within ambient temperature limits of -40 to 150°F (-40 to 65°C). Accuracy is specified as 1.6% FS; ANSI B40.1 Grade 1A, with a pressure limit rated at 110%. The gauges feature a 2-1/2" (63 mm) dial size and weigh 6.5 oz (184 g). Wetted materials are brass, while the housing is constructed of steel with a black finish and includes a polycarbonate lens.
Configuration Options
The series offers multiple measurement ranges configured for either bottom or back process connections. All models utilize 1/4" NPT fittings.
- Dial Size: 2-1/2" (63 mm)
- Housing Material: Steel with black finish
- Lens Material: Polycarbonate
- Wetted Materials: Brass
- Process Connections: 1/4" NPT, available in bottom or back orientation
- Measurement Ranges (Water Column): 0 to 15 w.c. (0 to 8.6 oz/in²), 0 to 32 w.c. (0 to 18.5 oz/in²), 0 to 55 w.c. (0 to 32.0 oz/in²), 0 to 100 w.c. (0 to 58.0 oz/in²), and 0 to 200 w.c. (0 to 116 oz/in²)
- Measurement Ranges (PSI): 0 to 5 psi (0 to 35 kPa) and 0 to 10 psi (0 to 70 kPa)
Key Product Differences
Variants within the Series LPG3 are distinguished by their pressure range and connection orientation. Model numbers follow a specific guide where suffixes indicate configuration; for example, models ending in 'N' denote bottom or back connections depending on the preceding digits (e.g., LPG3-D8122N vs. LPG3-D8142N). The series provides identical ranges across both mounting styles:
- Bottom Connection Models: Include LPG3-D8122N through LPG3-D9922N covering water column and psi ranges.
- Back Connection Models: Include LPG3-D8142N through LPG3-D0042N, offering the same range options with a 2-1/2" back connection offset.
