Gas Roots flow Meter with pluse output or 4~20mA
Product description:
The KKQY Gas Roots Flow Meter is a meter that
accurately measures gas flow and is based on a
volumetric measurement principle for accurately
metering the flow of gas through a closed conduit.The
flowmeter consists of a Roots flow sensor and a display.
It can be used to measure non-corrosive gases such as
natural gas, city gas, propane, nitrogen, and industrial
inert gases.Mainly used in gas commercial settlement
of catering, hotel and other industries, gas distribution
of gas distribution pipelines, gas pressure regulating
station measurement, industrial and civil boilers, etc.,
can also be used as standard flowmeters.
Product Features:
1.High accuracy and repeatability. The inner rotor is
precision machined and balanced, non-contact rotating
and well lubricated to ensure accurate flow meter accuracy and long working life;
2.The starting flow is small, the range is wide, and the pressure loss is small;
3.Good versatility, all specifications of the Roots flow sensor can use a universal display
4.Anti-electromagnetic interference, can prevent theft;
5.The instrument is explosion-proof and the explosion-proof mark is ExibIIBT4Gb, which can work in hazardous area 0, 1 and 2;
