Gas turbine flow meter is a new generation of high-precision, highly reliable gas precision instrument, with excellent low pressure and high pressure metering performance, a variety of signal output methods, and low sensitivity to fluid disturbance. It has been widely used in natural gas. Gas, liquefied gas, and light hydrocarbon gas is measured. Gas turbine flow meter requires a few important factors during the selection process, as they do not become loose due to measurement effects and stabilization.
The choice of gas turbomometer should be considered from the following aspects:
In general, the choice of turbomometer is mainly due to its high precision, the higher the accuracy of the flowmeter, and the more sensitive changes in the field conditions. Therefore, the accuracy of the meter should be selected. Be cautious should be considered from an economic perspective.
The choice of traffic range of turbine flows has a great influence on its accuracy and service life, and each mass flow meter has a certain measurement range. The selection of the flowmeter diameter also depends on the flow range. The principle of selecting a traffic range is that the smaller traffic during use should not be lower than the smaller traffic allowed by the flow meter, and the flow rate of larger traffic during use should not be higher than the greater flow allowed by the flow meter.
For gas turbine flow meter, the effect of fluid properties is mainly gas density, which has a great impact on the instrument factor, mainly in low flow regions. If the gas density is frequent, the flow coefficient of the flowmeter should be corrected.
Try using a low pressure loss turbine flow meter. Since the pressure loss of fluid through the turbomometer is less, the less energy consumed from the input to the output line, that is, the total power required will be reduced, thereby saving energy, reducing transportation cost, and improving utilization.
(1) The internal structure should adopt a reverse thrust turbine flowmeter. Since the anti-push structure can cause the impeller in a floating state within a certain flow rate, there is no contact point in the axial direction, no end surface friction and wear, can extend the life of the bearing.
(2) According to the pipe connection method, there are two horizontal and vertical installation methods. Horizontal mounting and pipe connection method is flange connection, thread connection and clamping.
