M201 Rotary Gas Meter Tester
Meriam’s M201 has new features to make drop testing Rotary (Natural) Gas Meters even easier! New hardware options protect the M201 from one sided overpressure. Options include a 1/4 turn valve manifold and an integral push-to-read cartridge valve in addition to the traditional push-to-read valve manifold. More importantly, new operating features provide users with a live pressure display and more automation to make field use easier than ever before.
The new Measure Mode lets the M201 be used as a conventional differential pressure measurement device. Users will appreciate the live pressure display as they check the handheld’s zero or observe DP across rotary gas meters. And when a drop test is made, the M201 uses an internal stop watch to measure the test length. The user only has to start and stop the test; the M201 reports both the test time and the average differential pressure measured during the test. Toggle the Min/Max key to see the minimum and maximum DP measured during the test.
