1. What is the unit of water vapor?

The unit of water vapor is kg/h or t/h, which is a type of mass flow unit. The mass of fluid passing through the effective cross-section of a closed pipeline or open slot per unit time. Corresponding to volumetric flow rate (the volume of fluid passing through per unit time), it can be expressed as the product of volumetric flow rate and fluid density. The mass flow method is mainly divided into direct method and indirect method. The entry provides a detailed introduction to mass and luminous flow meters, as well as the differences between mass flow meters and volumetric flow meters. The extended data quality flow meter can directly measure mass flow rate, density dynamic detection without compensation, and can also directly measure volumetric flow rate. However, volumetric flow meters can only directly measure volumetric flow rate. If a fixed density value is given to a canopy during configuration to measure mass flow rate, it will not be able to dynamically detect density and the accuracy will be slightly lower. Mass flow meters are expensive and provide accurate measurements, while volumetric flow meters are cheaper. However, they can be converted between the two. If the unit does not have money, try to choose volumetric flow rate and convert it to mass flow rate representation in software. The quality flowmeter measures gases without being affected by temperature and pressure. The quality flow meter detects density values in real-time, so it is independent of material temperature and pressure. Reference source: Baidu Baike - Mass Flow

2. Does the measurement of steam flow meter have a relationship with steam pressure and temperature

1. The measurement metho

d of steam flow meter is closely related to the pressure and temperature of steam. For water, due to its relatively stable density, it can be directly measured. However, for steam, its density changes with pressure and temperature, so compensation is needed. There are two main compensation methods for steam flow meters. The first type of Kaicong search is temperature compensation. The flow meter first accumulates the volume of steam, and then loads the pre stored density value at the corresponding temperature into the accumulator through a control unit (such as RCU), thereby calculating the weight flow rate of steam. The second compensation method is pressure compensation. This is because the pressure of saturated steam is directly proportional to its temperature. In the pressure compensation method, accurate steam flow can be obtained by measuring and compensating for the pressure of steam. For superheated steam, temperature compensation is required. Unlike saturated steam, the temperature and pressure of superheated steam are not proportional. Therefore, in the flow measurement of superheated steam, temperature must be used as a compensating parameter.

5. In the flow measurement of superheated steam, volumetric flow is first measured like saturated steam. Then, the density value of the superheated steam is inputted into the memory in advance through the control unit (such as ECU), and multiplied by the volumetric flow rate to obtain the true weight flow rate value.
