Realize direct and precise measurement of fluid mass flow without any conversion or correction of pressure, temperature, viscosity, density, etc. Its structure is composed of two parts: a sensor unit and a transmitter unit. Instruments are designed and manufactured in accordance with national standards for intrinsically safe and explosion-proof types. The mass flowmeter can directly measure the mass of the fluid, with low installation requirements (low requirements for the front and rear straight pipe sections of the instrument), reliable and stable operation, and low maintenance rate
進(jìn)口U型質(zhì)量流量計(jì) 科里奧利 科氏力質(zhì)量流量計(jì)原理 Coriolis mass flowmeter principle
科里奧利質(zhì)量流量計(jì)（Coriolis Mass Flowmeter）簡(jiǎn)稱科氏力質(zhì)量流量計(jì)，一個(gè)彎管道的兩端被固定，在兩個(gè)固定點(diǎn)的中間位置給管道施加振動(dòng)力（按管道的諧振頻率），使其以固定點(diǎn)為軸以其自然頻率u振動(dòng)，當(dāng)管道內(nèi)沒有流體流動(dòng)時(shí)，管道只受外加震動(dòng)力作用，管道兩個(gè)半段振動(dòng)方向相同，沒有相位差。當(dāng)有流體流動(dòng)時(shí)受管道內(nèi)流動(dòng)的介質(zhì)質(zhì)點(diǎn)科氏力Fc的影響，管道的兩個(gè)半段按相反的方向發(fā)生扭動(dòng)，產(chǎn)生相位差，這一相位差同質(zhì)量流量成正比，這就是科氏質(zhì)量流量計(jì)的工作原理.Coriolis Mass Flowmeter is referred to as Coriolis force mass flowmeter. Both ends of a curved pipe are fixed, and vibration force (based on the resonance frequency of the pipe) is applied to the pipe at the middle of the two fixed points, making it vibrate at its natural frequency u with the fixed point as the axis. When there is no fluid flow in the pipe, the pipe is only subjected to external vibration force, and the vibration directions of the two halves of the pipe are the same, without phase difference. When there is fluid flowing, influenced by the Coriolis force Fc of the medium particles flowing in the pipe, the two halves of the pipe twist in opposite directions, resulting in a phase difference that is proportional to the mass flow rate. This is the working principle of a Coriolis mass flowmeter
