Rotary meter delta itron gas

Rotary meter delta itron gas

Delta meters are volumetric meters. The flow of gas moves the pistons and each rotation traps and transfers a specific volume of gas.
The movement is mechanically transmitted to the totaliser through the magnetic coupling.

Delta meters are designed to measure natural gas and various filtered, and noncorrosive gases. They are used when very accurate measurement is required, when the gas flow can be low or irregular.
Due to the volumetric principle of the Delta meter, its metrology is not influenced by installation conditions. Consequently, it can be used to build very compact stations without installing a straight pipe inlet before the meter. Delta meters are approved for fiscal use.


  • A Delta meter is made of 5 main parts:
    A measuring chamber that is limited by the body and the 2 base plates
  • 2 pistons, which are synchronised by 2 gears and which rotate in opposite directions
  • 2 lubrificant covers
  • A magnetic coupling to transmit the movement of the pistons to the totaliser
  • A totaliser to register the measured gas
