RCM Industries 1 2-73-VUL-3-N Flow Meter Gauge

RCM Industries' Flo-Gage Direct Reading Flow Meter, model 1/2-73-VUL-3-N, is a rugged differential-pressure flow meter for liquids and gases that provides a direct reading of flow rate across industrial processes. This 1/2-inch nominal size unit is rated to 180 PSIG and 212 F, and the 73 code indicates a stainless steel corrosive service variant (316 stainless) within the Flo-Gage line. The device operates by measuring the pressure drop across an orifice and deriving flow from the square root of that differential pressure, a foundational principle of RCM's direct-reading meters. The Flo-Gage family supports pipe sizes from 1/4" to 8" and offers various material and connection options, with the 1/2" size appearing in the 7000-series variants, including VUL and related configurations.
