Orfice meter history
WitrynaHISTORY Samuel Clegg made the first practical gas meter in Eng-land in 1815. It was a water-sealed rotating drum meter that was improved in 1825; however, it was still very costly ... There are several different types of inferential meters, but the most common are the orifice, the turbine and the ultra-sonic meters. Every meter must have a way ... WitrynaMetering orifice systems can be used to balance flows to burners and monitor air/gas ratios. Through careful use of orifice meters, combustion systems can be adjusted for maximum fuel economy. 3/4" through 2" metering orifice assemblies include an orifice plate, two pressure tap plates, gaskets, pipe flanges, and bolts. Larger sizes consist of ...

WitrynaOMG can be installed at each burner’s air and gas connection and in the main air header or gas manifold for the furnace. The rugged construction of theOMG series orifice meters allow pressure up to 25 psig (172kPa) for the 3/8" to4" size (DN 10 to 100). The 6" through 28" (DN 150 to 700) sizes are suitable for 10 psig (69 kPa) service.
