Can We Help You?
Our product experts are here to help you find the right solution for your application!The M201 Rotary Gas Meter Tester is specially programmed to measure the differential pressure, and display the true average of those measurements. The amount of time over which the averaging occurs is controlled by the user. This feature addresses the flow surge and pulsation concerns.
The M201 Rotary Gas Meter Tester has an accuracy of 0.1% FS (28 in H2O range) or 0.05% FS (200 in H2O range). This provides better accuracy in the low DP ranges as compared to mechanical gauges or manometers. The M201 Rotary Gas Meter Tester is well suited for use in the field, its accuracy is not affected by temperature over its calibrated range of 23ºF - 122º F. This temperature effect on mechanical gauges, liquid manometers and some digital indicators can result in serious accuracy errors.
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 in 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.
All models include a protective red boot, four (4) AA alkaline batteries, and a hard copy user's manual. N.I.S.T. Certificate with Data (Z1065) is also included with all models. Intrinsically safe certification is available.
Two equalizing valve / manifold options are available:
• PRT: Push-to-Read valve equalizing manifold, normally open, brass, 1/8 in NPT (female) connections (for 2-port pressure manifold only)
• QTV: 1/4 Turn Valve equalizing manifold, manually equalize and isolate, brass, copper, 1/8 in NPT (female) connections (for 2-port pressure manifold only)
• Digital display
• Push-to-read valve
• Min/Max capture
• Field recalibration (for zero, span, and linearity)
• Auto shut-off programmable at 10, 20, 30, 45, and 60 min
