1. What is the unit of CMF? CMF is not a universal unit, but refers to the Coriolis Mass Flow Meter. This is a unique device for measuring fluid mass flow rate, and its working principle is very clever. The core of the Coriolis mass flowmeter lies in its design, which consists of two parallel U-shaped tubes. The bent parts of these two pipes vibrate with each other, and at the same time, when fluid is introduced into the pipe and flows forward along the pipe, it will follow the pipe to produce up and down vibrations. This design makes flow measurement direct and highly accurate, accurately capturing the mass flow information of the fluid. By observing and analyzing the influence of fluid on the vibration of U-shaped tubes, Coriolis mass flow meters can provide real-time measurement of fluid flow states and are commonly used mass flow measurement tools in contemporary industrial and scientific research fields. 2. What is the unit of cmf
Coriolis Mass Flow Meter (CMF) is a novel instrument that directly and precisely measures the mass flow rate of fluids. The main structure adopts two parallel U-shaped tubes, and the bent parts of the two tubes vibrate slightly towards each other. The straight tubes on both sides will vibrate accordingly, that is, they will approach or open at the same time, that is, the vibration of the two tubes is synchronous and symmetrical.
. If fluid is introduced into the pipe while synchronously vibrating, causing it to flow forward along the pipe, the pipe will force the fluid to vibrate up and down together with it. In order to resist this forced vibration, the fluid will give the tube a reaction force perpendicular to its flow direction, which is called the Coriolis effect force. Under this force, the vibration of the tube is not synchronized, and there will be a difference in the timing of vibration between the inlet and outlet sections of the tube (the difference is due to the opposite flow direction of the fluid in the inlet and outlet sections), which is called the phase time difference. This difference is directly proportional to the mass flow rate of the fluid flowing through the pipe. If the magnitude of this time difference can be detected through the circuit, then the size of the mass flow rate can be determined. This type of flowmeter is called the Coriolis direct mass flowmeter, and its biggest difference from dozens of conventional volumetric flowmeters currently in use in the world is the size of the mass it measures, measured in kg/h. A flow meter that uses mass (such as kilograms) as a unit is more accurate and constant than a volumetric flow meter that uses volume (such as liters or cubic meters) as a unit. Because quality follows the law of conservation. The invention of Coriolis mass flowmeter is the result of decades of hard work in the technology industry. It not only has accuracy, repeatability, and stability, but also has no flow blocking elements or movable parts in the fluid channel, so it has good reliability, long service life, and can measure the flow rate of high viscosity fluids and high-pressure gases. The measurement of clean fuel compressed natural gas (CNG) used in automobiles now relies on its accuracy, and its application is becoming increasingly widespread in industrial sectors such as petroleum, chemical, metallurgy, building materials, papermaking, pharmaceuticals, food, biotechnology, energy, and aerospace. Its emergence has brought about a profound c
