1. Types and principles of mass flow meters
Types and principles of mass flow meters Mass flow meters are instruments that measure flow based on the mass of the spent fluid, and are widely used in industrial fields such as petrochemicals, pharmaceuticals, food processing, aerospace, etc. There are various types of them, and the working principles of each type are also different. Here are several common mass flow meters and their principles:
1. Thermal mass flow meter principle: Thermal mass flow meters use the heat of the measured fluid to determine its mass flow rate. It is used in conjunction with both heating and temperature sensors, with electronic instruments measuring the resistance at the sensor location and converting it into a flow signal. When the fluid flows through the sensor, it will take away some heat, causing the temperature of the sensor to drop and the resistance to change. By measuring this resistance change, the mass flow rate of the fluid can be calculated.
2. Principle of Ultrasonic Mass Flow Meter: Ultrasonic mass flow meters use the relationship between the propagation speed of ultrasonic waves at a certain frequency in the fluid and the flow rate to measure the mass flow rate.
. It usually uses 2 to 4 sound sources to record and receive, measuring parameters such as the time and velocity of sound waves propagating in the fluid. Due to the influence of factors such as fluid density and flow velocity on the propagation speed of ultrasound in fluids, the mass flow rate of the fluid can be calculated by measuring these parameters.III. Principle of Rotary Mass Flow Meter: Rotary mass flow meters use the force of fluid on the rotor to measure flow rate.
. When flui
4. Principle of Gravity Mass Flow Meter: Gravity mass flow meter measures flow rate by utilizing the gravity effect in the fluid inside the flow meter with a device hung on the pipeline.
. When fluid flows through the device, the device will experience a certain amount of tension or pressure due to the effect of gravity. By measuring the changes in tension or pressure, the mass flow rate of the fluid can be calculated. This type of flowmeter is commonly used to measure fluids in high temperature and high pressure environments.Fifth, Coriolis mass flowmeter (Coriolis force mass flowmeter) principle: Coriolis mass flowmeter uses the modulation effect of fluid mass flow on the oscillation of the vibrating tube, that is, the Coriolis force phenomenon as the principle to measure mass flow.
. When fluid flows through a vibrating tube, it generates a Coriolis force proportional to the flow velocity, causing a change in the vibration frequency or phase of the vibrating tube. By measuring this change, the mass flow rate of the fluid can be calculated. In addition, the Coriolis force mass flowmeter can also measure parameters such as the density and volumetric flow rate of the medium. Coriolis mass flowmeter has the advantages of high measurement accuracy, wide range, and good stability, and is widely used in industries such as petroleum, chemical, food, pharmaceutical manufacturing, pa
