How much does a thermal mass flowmeter cost?
2. What kind of flowmeter is a steam flowmeter orifice plate and what are its advantages?
The steam flow meter orifice plate is a type of differential pressure flow meter that is mainly used for gas and steam flow measurement. It has the advantages of high accuracy and good stability. In the process of steam seepage flow measurement, maintenance is not required, greatly improving the efficiency of on-site use..
3. Boiler steam flowmeter, consult experts to determine the problem
Water evaporates into steam, and its expansion ratio is 1860 times under normal pressure.
. Under different pressures, its density also changes accordingly. Below are the answers to your questions one by one:1. The steam flowmeter consists of two broad trace parts. The first part is the sensor part, which is commonly known as the flowmeter. The equipment installed on the pipeline includes vortex street, orifice plate, Annubar, pulse and other forms. The second part is the integrated computing device, which includes functions such as calculation and display. It calculates the instantaneous flow rate and cumulative flow rate based on the pulse signal transmitted by the sensor, combined with the pressure signal and positive signal, and also has a recording function. This pressure signal is actually the density corresponding value that has already been set. So, you dont have to worry about density changes affecting accuracy.
2、 The second question has already been clarified in the above answer. The density and enthalpy of water vapor at different pressures are different. You can find it on the soda characteristics table.
3、 Regarding the third
4. Introduction to Steam Flowmeters
Steam is mainly measured using orifice plates, vortex flowmeters, etc. Among them, vortex flowmeters are more common and are mainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, vapors, and other media.
. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can be stable for a long time. The vortex flowmeter adopts a piezoelectric stress sensor with high reliability and can operate within a temperature range of -20 ℃ to+250 ℃. There are analog standard signals and digital pulse signals output for excavating beams, which can be easily matched with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.
