Meriam M201-DN0200

M2 Series Smart Manometer

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 ¼ 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.

With hundreds of original M201s at work in the field, Meriam recognizes that some customers will want to continue using the legacy software to stay consistent within their company. The new M201 includes a Mode Selection menu option for Legacy or Enhanced modes the users chooses which mode is best for them!

The digital display eliminates parallax errors, and depending on the range of the gauge, it can have a resolution of 0.01 or 0.001” H2O. A min/max feature also allows the user to see the minimum and maximum pressures recorded during the test. The unit is portable, and with the integral push to read manifold, the M201 Rotary Gas Meter Tester can safely be used with lines having a static pressure of up to 150 PSIG.
