A MICRO MANOMETER SYSTEM FOR MEASUREMENT OF ULTRA LOW GAUGE/DIFFERENTIAL PRESSURE

摘要

A micro manometer system for the measurement of ultra low gauge /differential pressure, which would achieve an accuracy of +/- 0.1mm. wc or better. Importantly, the micro manometer system of the invention is adapted to provide readings, which would be stable and repeatable and hence reliable for such measurements. Importantly, the micro manometer system of the includes a graduated and slidable scale, a dial-gauge mounted on the frame with a tube manometer preferably selected form glass U-tube and single tube manometer requiring multiplication factor equal to the ratio of cross sections of manometer tube limb and the liquid pot mounted on the frame above said scale and a plate means fixed to the scale adapted to pulse the plunger of the dial gauge adapted for desired readings. The system is adapted with user friendly features to favour wide scale acceptability and use as a micro manometer system for the measurement of ultra low gauge / differential pressure.
