What is the meaning of the fan flow unit CMF?
This refers to the fact that the Coriolis Mass Flow Meter (CMF) is a novel instrument that directly and precisely measures the mass flow rate of fluids, and its unit is; It is ft3/min, 1m3/s=2119ft3/min
2. What is the unit of cmf
1. cmf is the Coriolis Mass Flow Meter CMF, which is a novel instrument for directly and accurately measuring fluid mass flow. 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.
2、 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, 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.
3、 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
4、 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, metallurgical, building materials, papermaking, pharmaceuticals, food, biotechnology, energy, and aerospace. Its emergence has brought about a profound change in fluid measurement technology and is praised by experts as the mainstream flowmeter of the 21st century.
3. What are the functions and classifications of flow meters?
Classification by medium: Liquid flow meters and gas flow meters are classified by measurement method: velocity type (such as vortex flow meters, swirl vortex flow meters, turbine flow meters, ultrasonic flow meters, etc.); Differential pressure flowmeter (orifice flowmeter, V-cone flowmeter, etc.); Volumetric flow meters (elliptical gear flow meters, Roots flow meters, membrane gas meters, etc.); Mass flow meters (Coriolis mass flow meters, calorimetric mass flow meters, etc.); Open channel flow meters (Bacher troughs, triangular weirs, etc.
