Common Affecting Factors of Gas Mass Flow Meters

Common factors affecting gas mass flowmeters Mass flowmeters are based on the principle of thermal diffusion, that is, when a fluid flows through a heating object, the amount of heat lost by the heating object is proportional to the flow rate of the fluid. Specifically, the sensor of the flowmeter has two standard and RTDs, which have been used as a heat source and used to measure the temperature of the fluid. When the fluid flows through, the heat loss of the heat source has a nonlinear relationship with the flow rate, and the quality of the thermal gas The flow meter can convert this relationship into a linear output of the measured flow signal. The gas mass flowmeter is designed and produced based on the principle of thermal diffusion. This product is widely used in steel mills, coking plants, petroleum, chemical, thermal, medical, thermal power plants, environmental protection and other industries. The gas mass flowmeter is a real direct mass flowmeter, and the user does not need to compensate the pressure and temperature. The instrument has no moving parts, small pressure loss, wide range ratio, high precision, high reliability, simple installation and convenient operation. So what are the common influencing factors of gas mass flowmeters? There are many factors that affect the flowmeter. Briefly talk about the common influencing factors: (1) Pressure The pressure of the gas measured by the CMF used in the dispenser is not lower than 20MPa, and the pressure is far greater than the atmospheric pressure. The high pressure changes the internal stress of the vibrating tube and increases the equivalent stiffness of the elastic tube, thereby increasing the vibration frequency of the vibrating tube and reducing the phase difference between the two tubes; when the gas flows through the vibrating tube, there is a pressure drop, which makes the vibrating tube The force is asymmetrical, which also affects the phase difference. (2) Temperature The working temperature of the CMF used in the dispenser is much lower than the room temperature, and the influence of temperature must be considered; changes in the medium temperature or ambient temperature will change the Young's modulus of the measuring vibrating tube and affect the structure of the zero drift and other factors. (3) Flow rate Compressed gas has low density and fast flow rate, and its influence cannot be ignored. Ideally, as the flow rate increases, the vibration frequency of the vibrating tube decreases. Generally, the change of fluid density is small, and it can be considered that the flow rate is proportional to the mass flow rate of the fluid. Therefore, the compensation of flow rate can be converted into a nonlinear factor of flow rate change for compensation.
