Meriam ProcessTechnologies” M2 smart manometer, part of the MSeries line of test instruments and calibrators, is the first in a sequence of handheldinstruments that are designed to simplify pressure calibration andmonitoring. The manometer features a compact, ruggeddesign that makes it a good fit for field applications. Its accuracy allows itto serve as a pressure reference standard. Features include:• 11 selectable user units (consult factory for custom user units) • Expanded ranges to handle gauge, differential, absolute, or vacuum pressure• Min/Max feature to capture extremes of varying pressure signals • One-point or five-point field recalibration for zero, span, and linearity• Leak test procedure to calculate leak rate in units selected per minute • Flow function to display square-root flow rated in user-defined units• Custom-molded protective rubber boot• Polycarbonate enclosure with permanently static dissipative, ESD protection (6.5″ _ 3.6″ _ 2.25″)Applications include:• Calibration of field devices (pressure gauges, transmitters, recorders, and switches)• Pressure drop across filters and rotary vane meters• Open flow measurement of gas wells with a pitot tube or orifice plate• Verification of vacuum pumps and barometers• Pharmaceutical process monitoring (low pressure or vacuum)
