The Coriolis mass flowmeter is an instrument that measures the mass flow rate of fluids by utilizing the Coriolis effect. The Coriolis effect refers to the fact that when a fluid passes through a laterally constrained pipe, due to the fluid’s own rotation and the collisions between fluid molecules, a lateral temperature difference perpendicular to the fluid flow direction and the magnetic field direction will be generated. The Coriolis effect is caused by the interaction between the magnetic field induced by the current passing through a laterally constrained wire and the electrons and ions in the fluid.

How to quickly solve faults encountered during the use of air vortex flowmeters

Vortex flowmeter is a new flowmeter successfully developed on the basis of Karman vortex principle. Vortex flowmeter is suitable for measuring the mass flow and volume flow of superheated steam, saturated steam, compressed air, general gas, water and low corrosive liquid. How to ensure the accuracy of vortex flowmeter measurement during installation?

Vortex flowmeter is one of the commonly used instruments in daily production, therefore, failure will occur from time to time, the main reasons for the inaccurate flow accuracy of the vortex include: the influence of temperature on the measurement, the influence of the accumulation of the vortex generating body on the flow surface, the influence caused by the inconsistency between the distribution tube and the inner flow meter.

Electromagnetic flowmeter is composed of two parts: sensor and converter. It is based on Faraday’s law of electromagnetic induction, used to measure the volume flow of conductive liquid with an electrical conductivity greater than 5μS/cm, is a kind of induction instrument to measure the volume flow of conductive medium.

Thermal gas mass flowmeter based on the principle of thermal diffusion, using constant temperature difference method designed, is a gas measurement instrument.

The reason why the measurement error is large is that the amount of oil and suspended matter in the water from the sewage station is high, and the treated sewage has a small amount of oil and suspended matter in the water, and the error of electromagnetic flowmeter measurement is also small.

1. Vibration effect

Compressed air is generated by air compressor or high pressure fan. When these devices are in operation, they all have varying degrees of vibration, and sometimes the vibration is relatively strong, and this vibration is transmitted through the connecting pipe. When selecting and determining the position of the vortex flowmeter, this influencing factor should be fully considered. In various detection methods, the anti-vibration performance of the instrument is not the same due to different detection components. For the vortex street of the detection element, the vibration resistance can reach 0.5~1G. When determining the installation position of the vortex flowmeter, it should be as far away from the power equipment such as air compressors and fans as possible.
