Turbine Gas Meter

TGM Gas Turbine Flow Meter is a kind of instrument for precisely measuring the gas flow, which is suitable for the measurement of all kind of gas in the fields of industry, such as natural gas, city gas, propane, butane, ethane, air and nitrogen, etc.

Pressure loss TGM

The average pressure loss of the TGM turbine meter using atmospheric natural gas with a density of 0.8 is measured at one (1) diameter upstream to one (1) diameter downstream of the meter on straight pipe of the same size as the meter. * according to diameter.
