GAS ROOTS FLOWMETER
KKQY Gas Roots Flowmeter is an instrument for accurately measuring gas
flow. Based on the principle of volumetric measurementit is used to accurate-
ly measure the gas flow through a closed pipeline.The flowmeter is composed
of two parts: a roots flow sensor and a display instrument It can be used to
measure non-corrosive aases such as naturalaas city aaspropane nitroaen.
and industrial inert gases.Gas metering in distribution networks gas pressure
requlating stations industrial and civil boilers etc. can also be used as stan-
dard flow meters.Technical Parameters
