Why do flow meters need temperature and pressure compensation?

Abstract: Why do flowmeters need temperature and pressure compensation information is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. 1. When the flowmeter measures the gas, it needs to compensate the temperature and pressure at the same time; the gas is generally settled by the standard volume flow rate. Because the volume flow of the gas changes when the temperature or pressure changes, the flow will change. 2. When measuring superheated steam, the same temperature and pressure are required. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of why flowmeters need temperature and pressure compensation. 1. When the flowmeter measures the gas, it needs to compensate the temperature and pressure at the same time; the gas is generally settled by the standard volume flow rate. Because the volume flow of the gas changes when the temperature or pressure changes, the flow will change. 2. When measuring superheated steam, temperature and pressure need to be compensated at the same time; steam is generally settled by mass flow. Because there is a change in either temperature or pressure, the density of the steam will change and the mass flow will also change. 3. When the flowmeter measures saturated steam, single temperature compensation or single pressure compensation is required. The density of saturated steam has a fixed correspondence with temperature or pressure (saturated steam density table), knowing any of them, the density of saturated steam can be determined. 4. When measuring liquids, pressure compensation is generally not required. Below 5MPa, only the influence of temperature is generally considered, and temperature compensation is required for accurate measurement. In general measurement, no compensation can be used; when measuring some hydrocarbons (such as crude oil), temperature and pressure compensation is generally required. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Why do flow meters need temperature and pressure compensation'
