What flow meter is used to measure superheated steam/saturated steam? Vortex flowmeters are generally used to measure superheated steam and saturated steam. To ensure measurement accuracy, appropriate temperature or pressure compensation should be selected based on the characteristics of both. Saturated steam: Water is heated at a certain pressure until it boils and vaporizes. At this point, the steam temperature is equal to the saturation temperature, which is called saturated steam. The saturation pressure and saturation temperature correspond to each other, and both pressure compensation and temperature compensation can be used during measurement. Due to the relatively easy pressure compensation and high measurement accuracy, pressure compensation methods are mostly used in practical applications, such as the use of LUB split vortex flowmeter embedded with HSYB pressure transmitter. Overheated steam: Saturated steam continues to be heated, and when the temperature rises and exceeds the saturation temperature at that pressure, it is called superheated steam. Superheated steam is a single-phase fluid with characteristics similar to gases. Its temperature and pressure are two independent variables, and its density is determined by both. When measuring, any change in temperature or pressure can cause a change in steam density, which in turn affects the mass flow rate. Therefore, temperature and pressure compensation must be performed simultaneously to ensure accuracy, such as when using a LUB split vortex flowmeter with HSYB pressure transmitter and WZPK platinum resistor. In addition, measuring the flow rate of high-temperature steam (superheated steam or saturated steam) can also use LUB integrated vortex flowmeter with temperature and pressure compensation function, which has relatively low cost.

2. What are the commonly used steam flow meters?

There are mainly two types of steam flow meters: differential pressure flow meters and vortex flow meters.. Differential pressure flowmeter: Overview: Differential pressure flowmeter is the most widely used type in steam flow measurement. It calculates the flow rate by measuring the differential pressure generated when the fluid flows through the throttling device. Classification: According to the different throttling devices, differential pressure flow meters can be divided into various types, such as orifice flow meters, nozzle flow meters, indicator Venturi flow meters, and averaging tube flow meters (including Annubar, Velbar, Probar, etc.). In addition, there is a special type of differential pressure flowmeter - balance flowmeter, which has unique advantages in certain specific situations. Characteristics: Differential pressure flow meters usually require temperature and pressure compensation when measuring steam flow to ensure the accuracy of the measurement results. In recent years, some advanced differential pressure flow meters, such as Frosts MVX100 multivariable integrated differential pressure flow meter, have achieved built-in temperature and pressure sensors, which can directly output mass flow without external compensation devices, greatly improving the convenience and accuracy of measurement. Vortex flowmeter: Overview: Vortex flowmeter is another commonly used steam flowmeter. It measures the flow rate by utilizing the proportional relationship between the vortex frequency generated by the fluid flowing through the vortex generator and the flow velocity
