Gas Roots Flow Meter Manufacturer, High Accuracy Gas Flow Meter

PRODUCT DISPLAY

Description

It is a positive displacement, rotary type gas meter designed for continuously measuring and indicating the accurate measurement of gas in a pipeline. Gas Roots flow meters are suitable for handling most types of clean, dry, common gases at either constant or varying flow rates. Meters of standard construction are not directly suitable for handling acetylene, biogas or sewage gas. Contact the factory for information on specially constructed meters made of materials directly compatible with these and other gases.

APPLICATION

For some gas industry business accounting which used in some fields,like, restaurant, hotels, gas pressure regulation station, civil
boiler, etc. Also available to measure some gases like, propane, nitrogen and others which have not corrosive mediums.
