1. How to use vortex flowmeter correctly?
Vortex flowmeter, also known as Karman vortex flowmeter. It is a separated flowmeter made using the principle of natural fluid oscillation. When a fluid flows through an object perpendicular to its flow direction at a sufficiently high velocity, if the size of the object is appropriate, a neatly arranged and opposite turning vortex column will be generated behind the object along two parallel straight lines. Among them, S is the Strouhal number, V is the average flow velocity inside the pipeline, and d is the width of the upstream face of the cylindrical body. Therefore, by measuring the frequency of the vortex, the flow velocity of the fluid can be determined, and the flow rate of the fluid can be measured. Precautions for sensor installation
(1) The sensor should be installed horizontally or vertically (the flow direction of the fluid should be from bottom to top) on the pipeline corresponding to the nominal diameter.
(2) When using a vortex flowmeter for flow regulation, special attention should be paid to installing the flow regulating valve behind the sensor, otherwise it is easy to generate jets at low flow rates, resulting in a fault phenomenon where the medium flow rate is inversely proportional to the valve opening during flow regulation.
(3) When installing the flowmeter, a certain length of straight pipe section should be configured for the upstream and downstream virtual stools.
(4) Flow meters should not be installed on pipelines with strong vibrations to avoid affecting measurement accuracy. Precautions for use
(1) In the water supply system, flow meters are generally installed in the instrument well. To prevent damage to

(2) When there is a high-power motor near the flowmeter, in order to avoid power frequency interference, in addition to adding shielding to the signal transmission cable, the signal transmission method should use DC signal as much as possible.
(3) The technical parameters of the flowmeter should be well documented and managed, such as the KQ coefficient and full frequency of the flowmeter. The loss of these data will cause great difficulties for the maintenance of the instrument in the future.
.(4) When using explosion-proof flow sensors, it is absolutely not allowed to open the instrument equipment casing on site while it is powered on. During maintenance, attention should be paid to protecting the casing, especially the explosion-proof joint surface, which cannot be damaged.
(5) The detection element should be regularly removed from the pipeline and cleaned with alcohol or gasoline.
