Why does vortex flowmeter have no flow display?

Vortex flowmeter is a velocity flowmeter, which measures the volume flow rate in the working state. If you choose the table according to the volume flow rate, the mass flow rate provided by the customer should be converted into the volume flow rate under the working state, and then determine the diameter of the selected instrument against the volume flow parameter.

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.

The vapor flowmeter has no moving parts, strong reliability, high precision, long life, and can measure the instantaneous flow and cumulative flow of liquid in a wide flow range.

Vortex flowmeter is also known as Karman vortex flowmeter. It is a separation flowmeter made of the principle of natural oscillation of fluid. When a fluid flows at a sufficiently large velocity through an object perpendicular to the direction of the fluid, if the object is of appropriate size, it will produce a neatly aligned and reversed vortex train behind the object along two parallel lines.

Vortex flowmeter is mainly used for the flow measurement of industrial pipeline medium fluids, such as gas, liquid, steam and other media. There are special phenomena and problems in the process of measurement. One of the key problems is that the vapor density value deviates too much from the design value, which brings significant measurement errors to the measurement results. At present, the density measurement instrument with mature technology has not been successfully applied, which brings certain difficulties to the steam flow measurement.
