1. What is the unit of CMF? CMF is not a unit, but an abbreviation for Coriolis Mass Flowmeter. The working principle of Coriolis mass flowmeter: vibrating tube structure: The main structure of Coriolis mass flowmeter is usually composed of two U-shaped tubes arranged side by side. The bent parts of these two pipes will vibrate towards each other, and the straight pipes on both sides will also vibrate accordingly. Fluid Introduction: When fluid is introduced into a pipe and flows forward along it, the pipe forces the fluid to vibrate up and down together with it. This vibration generates a Coriolis force proportional to the mass flow rate of the fluid. Characteristics of Coriolis mass flowmeter: Direct measurement: Coriolis mass flowmeter can directly measure the mass flow rate of fluid without the need for correction of parameters such as density, temperature, or pressure. High precision: Due to its unique working principle, Coriolis mass flowmeter can provide high-precision measurement results, suitable for various fluid media and flow ranges. Wide applicability: Coriolis mass flowmeter can be used to measure the mass flow rate of various fluid media such as gas and liquid, and is widely used in fields such as petroleum, chemical, power, metallurgy, etc. In summary, CMF, as an abbreviation for Coriolis mass flowmeter, plays an important role in the field of fluid measurement. Its high precision and wide applicability make it an indispensable tool in industrial measurement.

2. How is the mass of a mass flowmeter calculated? The mass flow meter directly or indirectly measures the mass flow rate of a fluid, and the specific calculation method depends on its working principle. The following are several main types of mass flow meters and their calculation methods for mass flow rate

1. * * Coriolis Mass Flowmeter * *: The Coriolis flow meter directly determines the mass flow rate by measuring the Coriolis force of the fluid inside the vibrating tube. When fluid flows through a U-shaped or spiral vibrating tube, it will cause distortion of the tube, and the degree of distortion is proportional to the mass flow rate flowing through it. By monitoring the vibration frequency and phase difference, the instrument can calculate the mass flow rate without the need for separate measurements of density, temperature, or pressure compensation.

2. * * Thermal Mass Flowmeter * *: A thermal mass flowmeter determines the mass flow rate by heating the fluid with a heating element and measuring the speed at which the fluid carries away heat due to its flow. The faster the flow rate, the more heat is carried away, resulting in a larger temperature difference between the two ends of the sensor. By combining the thermal properties of the fluid, such as thermal conductivity and specific heat capacity, the mass flow rate can be calculated. 3. Differential pressure mass flow meters (such as Delta P Flowmeters) indirectly calculate the mass flow rate by measuring the pressure difference generated before and after the fluid flows through the throttling device. When calculating, it is necessary to consider the density, flow velocity, and geometric dimensions of the throttling device of the fluid. Specific calculations usually follow the Bernoulli equation and related principles of fluid mechanics, and may require temperature and pressure compensation to determine the actual density of the fluid under working conditions.
