The principal of the Rotary Gas Meter is well known.This product 
totally meet European requirement and passed NMI EN12480 & R137-1 
test It is a positive displacement type of meter , passing 
pre-determined volumes of gas by means of two counter-rotating 
impellers. Four times per each revolution a fixed unit of volume is 
displaced through the measurement chambers. The flowing gas volume is 
proportional with the number of revolutions of the output. The output of
 this model Rotary Gas Meter is a special designed magnetic coupling 
where one part is fitted inside the meter body and the associated part 
is in the read-out unit. The read-out unit can either be a mechanical 
index or an electronic index with or without volume conversion and 
communication functions.
 
The typical a-symmetric design of the impeller tips allows considerable increased turn down ratios
