Natural gas turbine flowmeter
Description of natural gas turbine flowmeter :
Natural gas flowmeter is a kind of speed meter used to measure low viscosity the volume of a gas in a closed pipe flow and total amount. In petroleum, chemical industry, metallurgy, urban gas network industries has wide use value.
Features of natural gas turbine flowmeter :
1. Measurable flow rate is low, which is about a quarter of the vortex flowmeter, suitable for trade settlement
2. High accuracy, generally up to + / - 1.5%, plus or minus 1.0% R R
3. Repeatability, short-term repeatability of up to 0.05% - 0.2%
4. Can realize the integration of real-time temperature and pressure compensation, direct measurement standard flow state
5. Low pressure loss
6.The strong vibration resistance
