Gas turbine high pressure air flow meters for natural gas flow meter,Pipe size DN15-300
Introduction:
The Gas Turbine Flowmeter is a precision flow meter that can be used to measure fluid flow and total volume with the appropriate Flow Totalizer.Widely used in petroleum, chemical, metallurgy, scientific research and other fields of gas, natural gas, gas and other gas measurement and control systems.
The integrated Turbine Metering structure is explosion proof and shows the total amount of flow, the instantaneous flow and the percentage of full flow.
Battery with long-lasting lithium battery, single-function totalizer battery life of up to 5 years, multi-function display battery life of up to 24 months. Integrated header can display a large number of flow units, cubic meters, gallons, liters, standard cubic meters, standard liters, you can set a fixed pressure, temperature parameters to compensate for the gas, the pressure and temperature parameters change little occasion., You can use the meter for fixed compensation totalizer.
