Classification of measurement principles 1. Mechanics principles: instruments that belong to this type of principle include differential pressure type and rotor type using Bernoulli theorem; impulse type and movable tube type using momentum theorem;

​1. The transmitter of the vortex flowmeter stops the abnormal whistling sound: (1) The flow rate is too high, causing the generator or detection element to vibrate; (2) Cavitation occurs in the pipeline; (3) The generating body or detecting element is loose. Solution: In order to avoid damage to the generating body or detection components, the valve should be adjusted first to reduce the flow rate and the flow rate, and then further investigate the cause.
