rotary displacement gas meter

APPLICATION AND FEATURES

LYQ series gas rotary displacement meter is a volume type flow meter, because the measuring accuracy of this series meter is not affected by gas gravity, pressure and the changing of the flowrate, it is suitable for measuring the flowrates of non-corrosion gas such as natural gas, coal-made gas, inert gas and air etc. it is widely used in the fields of trade measurement and scientific researching because of its advantages of high accuracy, high reliability, wide rangability and long service life etc. It has compact and sturdy structure, there doesn't  need to have a straight pipe on the entrance of the meter, it is specially suitable for being installed in narrow occasions and it is widely applied to trade measurement for town gas and it is an ideal measuring device for petroleum, chemistry-industry, industry, domestic boiler, gas pressure regulating case, hotel, restaurant and the scientific and researching Dept.

1. Executing standard: JB/T 7385-1994 gas rotary displacement meter, JJG633-2005 gas volume type flow meter.
