Rotary Positive Displacement (Delta) Gas Meter allow extremely accurate flow measurement of Gases & Gas Mixture. The volumes (Under the Given temperature & pressure conditions at the time of measurement are displayed by direct read index.

The volumetric principle gives a high level of metrology for accuracy, dynamic measurement and reliability.

Description :

• A casing (or Body )
• A measuring chamber between the housing and two end plates
• Two pistons (or impellers) rotating in opposite direction, precisely correlated by the set of the timing gear
• Two lubrication end covers
• An index displays displaced volume translated from the rotation of the impeller

Measurement Principle :

Two pistons (or impellers), in the measuring chamber are designed in an <<8>> configuration .The flow of Gas Moves the pistons, each rotation traps & transfer a specific volume of gas.

This movement is mechanically transmitted to index which integrates the number of revolutions & directly displays the displayed volume (in M3 Or ft3).

Diaphragm Type Gas Meter features a robust design and exact measurement of volume flow rates with low-pressure losses. It is manufactured according to DIN EN ISO 9001.

Measuring accuracy of Diaphragm Gas Meter is secured by a plastic diaphragm which guarantees long-term stability, a proven control mechanism & low-pressure losses.
