一、进口夹套保温质量流量计概述

夹套质量流量计是在流量计外侧加一层保温夹套，在夹套内注入蒸汽、导热油等高温介质，通过热传递，使流量计内的介质保持一定温度，从而计量流经管道内的液体的质量流量，实现精准测量。

夹套保温质量流量计在工业过程中具有重要的应用，特别适用于需要同时进行质量流量测量和保温的场合。它可以广泛用于化工、石油、制药、食品等行业，以确保流体流量和温度的准确控制和监测。

A jacketed mass flowmeter is a device that adds a layer of insulation jacket on the outside of the flowmeter, and injects high-temperature media such as steam and thermal oil into the jacket. Through heat transfer, the medium inside the flowmeter maintains a certain temperature, thereby measuring the mass flow rate of the liquid flowing through the pipeline and achieving accurate measurement.

The jacketed insulation quality flowmeter has important applications in industrial processes, especially suitable for situations where mass flow measurement and insulation need to be carried out simultaneously. It can be widely used in industries such as chemical, petroleum, pharmaceutical, and food to ensure accurate control and monitoring of fluid flow and temperature.

二、进口夹套保温质量流量计工作原理

科里奥利力(Coriolis effect)，简称：科氏力，是对旋转体系中进行直线运动的质点由于惯性相对于旋转体系产生的直线运动的偏移的一种描述。  

质量流量计是科里奥利力的典型应用，它让被测量的流体通过一个振动中的测量管，流体在管道中的流动相当于直线运动，测量管的振动会产生一个角速度，由于振动是受到外加电磁场驱动的，有着固定的频率，因而流体在管道中受到的科里奥利力仅与其质量和运动速度有关，而质量和运动速度即流速的乘积就是需要测量的质量流量，因而通过测量流体在管道中受到的科里奥利力，便可以测量其质量流量。

The Coriolis effect, abbreviated as Coriolis force, is a description of the displacement of a particle undergoing linear motion in a rotating system due to inertia relative to the linear motion of the rotating system.

A mass flowmeter is a typical application of Coriolis force, which allows the fluid being measured to pass through a vibrating measuring tube. The flow of the fluid in the pipeline is equivalent to linear motion, and the vibration of the measuring tube produces an angular velocity. Since the vibration is driven by an external electromagnetic field and has a fixed frequency, the Coriolis force that the fluid experiences in the pipeline is only related to its mass and velocity. The product of mass and velocity, that is, the flow velocity, is the mass flow rate that needs to be measured. Therefore, by measuring the Coriolis force that the fluid experiences in the pipeline, its mass flow rate can be measured.
