Feature
- Coriolis flow meter principle is can directly measure the mass flow of fluid, wide measuring range, high accuracy.
- Coriolis flow meter installation requirements are low, no front and rear straight pipe section requirements.
- In addition to normal fluid measurement can also measure the general fluid measurement instrument is more difficult to measure the industrial media, such as high-viscosity fluids, slurries, suspensions and so on.
- On-line measurement of the measured medium density, temperature and other parameters, and thus derived from the measurement of the concentration of solutes in solution, reliable operation, low maintenance.

Drip Protection Schematic

Attention
- All housing screws, housing covers and cable entry glands must be tightened.
- The mass flow meter housing gasket must be clean and intact when inserted into the sealing groove. The gasket may be dried, cleaned and replaced if necessary.
- All wiring should be drip-protected, i.e. the cable inlet of the meter, the cable and the feed-through pipe should have a downward bend to avoid water ingress and short-circuiting.
- All cable inlets must not face upwards without protection.
- Unwanted cable inlets need to be sealed with plugs.
Application

Tips: What is a coriolis mass flow meter?
A coriolis mass flow meter is an instrument used to measure the flow of a fluid, based on the principle of the coriolis effect. Coriolis flow meter working principle that when a fluid flows through a pair of vibrating pipes, the flow of the fluid has an effect on the vibration of the pipes.
The mass flow rate of the fluid is directly proportional to the change in this vibration, so by detecting the change in vibration the mass flow rate of the fluid can be accurately calculated. Coriolis flow measurement is widely used for flow measurement of gases, liquids and steam.
