WT series gas turbine flowmeter is a high-precision, high-reliability precision measuring instrument. It is suitable for the measurement of various single-phase
gases and the measurement of gas in urban gas, petroleum, chemical, electric power, metallurgy and other industries.
WT series gas turbine flowmeters have excellent low-pressure and high-pressure measurement performance, suitable for accurate measurement of large flow gas.
According to user needs, our company can provide turbine flowmeters with different accuracy levels and different performances.
Note: ①The flow range listed in the table is the flow range of the product at the factory inspection (the medium is air at normal temperature and normal pressure);
②As the pressure increases, the flow range also expands.

2.1.1 Product type test verification number 2019F305-33.
2.1.2 Accuracy class
a.Use the high repeatability of the turbine flow sensor to linearly correct the meter coefficients (normally no correction is required). The accuracy level within the range is: Level 1.0 and 1.5. Ifno linear correction is performed, according to the IS09951
1.0 level: 0.2Qmax ~ Qmax: +1.0%; Qmin ~ 0.2Qmax: +2.0%
1.5 level: 0.2Qmax ~ Qmax: +1.5%; Qmin ~ 0.2Qmax: +3.0%
b. Temperature indication error: s +0.5%
C. Pressure indication error:≤+0.2% (220%Pmax) (upper limit of pressure sensor range Pmax: 0.2, 0.5,1.0,5.0,10(ab Mpa))
