What is gas turbine flow meter?
Turbine flow meter gas is a kind of in line volumetric flow meter , this industry gas flow meter is a speed type flowmeter, it has small pressure loss, high accuracy, low starting flow, large turndown ratio, anti-vibration and resistance .
The turbine flowmeter for gas uses a turbine for measurement. Gas turbine flow sensor first converts the flow rate to the speed of the turbine, and then converts the speed into an electrical signal proportional to the gas flow. This kind of gas flow transmitter is used to detect instantaneous flow and total integrated gas flow. Its output signal is frequency or 4-20mA, which is easy to digitize in oil and gas industry.
Types of turbine flow meter are gas turbine flow meter and liquid turbine flow meter.
Applications for turbine flow meter gas
Turbine flow measurement can be used in below applications:
Non aggressive gases, air, volume of fuel gases, fuel gases, natural gas, natural gas turbine meter
,city gas, LPG gas, Liquified Natural Gas (LNG),biogas (Gas composition ratio: CH4, CO2, H2S, CO2 Gas phase) , ethylene, utility gas flow, methane, propane, butane, ethane, coke oven gas, town gas, acetylene, nitrogen, carbon- dioxide, air and all inert gases, nitrogen, noble gases, argon gas, helium gas,, hot air , To monitoring incoming LPG gas consumption or LPG gas through a pipe between bulk cylinders and consumer cylinders, Refrigerant RA 13 gas, pure hydrogen., cooking gas , air and gas flow to a burner system, blast furnace recycle gas (flammable gas),natural Gas (purge Gas) Flowmeter for Billing Purpose….

Gas turbine flow meter price
Gas turbine flow meter price is determined by many factors:
Gas flow meter size: The larger the size, the more expensive. For example, the price of 1" gas sensor is much cheaper than 8".
Whether it is high pressure gas turbine flow meter, such as natural gas turbine meter with ANSI, 300LB, 600LB, high pressure gas turbine is much more expensive
Whether temperature and pressure compensation and correction , EVC needed.
Turbine flow meter manufacturers and brands : Blancett, Elster gas flow meter , Halliburton turbine flow meter, Honeywell gas meter has high cost, while gas turbine flow meter from China flow meter factory are now cheap , also with reliable performance. it can be a good replacement or alternative.
