High temperature Coriolis flow meter

What is High temperature Coriolis flow meter?

High temperature Coriolis flow meter is a flowmeter that uses the principle of modulation of the fluid mass flow rate on the vibration of the vibrating tube to measure the mass flow rate, the max  fluids temperature for the high temperature Coriolis flow sensor is 350°C( 662). There is no need for temperature and pressure compensation, and the mass flow rate of the fluid is directly measured by high temperature

Coriolis force was discovered by French scientist Coriolis. When a mass point moves on an implicated coordinate system in a rotary motion, the absolute acceleration of the particle contains an additional acceleration in addition to the relative acceleration and the implicated acceleration. This additional acceleration is Coriolis acceleration, or Coriolis acceleration for short.
Considerations when buying a correct a high temperature Coriolis flow meter

There are many manufacturers of Coriolis mass flow meters, and the types, shapes and models are even more diverse. In the selection work, you can consult the technical engineer from Coriolis flow meter manufactures or you can also use special selection software to help you choose the correct type high temperature Coriolis flow sensor. In this section, the composition, specifications, functions and main technical indicators of some typical products will be selected and briefly introduced, so that readers have a further overview of the Coriolis mass flowmeter.
High temperature Coriolis mass flow meters are usually composed of high temperature flow sensors and Coriolis flow transmitters, the two parts are connected by the cable, remote version Coriolis flow meter is necessary for high temperature mass flow measurement ,because the high temperature fluids could cause damage on electronic parts of Coriolis flow transmitter. The following technical specifications should be considered to the high temperature Coriolis flow meter: flow range, working temperature, working pressure, accuracy and repeatability, as well as the installation, the wet parts material of mass flow sensor, and so on. The technical specifications of the mass flow transmitter should include: power supply, signal and output mode, signal transmission range and accuracy, signal display resolution, etc. and the most important part is high temperature Coriolis flow meter price.
