2. Rotary turbine flow start stop Table steps?

① Close the exhaust valve and intake valve first. ② Slightly open the air outlet valve, then slowly open the inspection air inlet valve to slowly start the meter, and then slowly open the air outlet valve and alarm valve to achieve normal operation. It is necessary to prevent sudden start and damage to the meter core. ③ When carrying spring eggplant, the exhaust valve should be closed before closing the intake valve, and the above regulations should be followed every time it is started.

3. Working principle of intelligent vortex flowmeter

Working principle of intelligent vortex flowmeter: Intelligent vortex flowmeter is a flow measurement instrument based on fluid dynamics principles, and its working principle mainly depends on the vortex flow generated by the fluid in a specific structure and its precession phenomenon.

First, the structural characteristics of the flow sensor. The flow profile of the intelligent vortex flowmeter flow sensor is similar to the profile of the Wenqiu Li tube Qingzi rent, which helps the fluid to form a stable flow state inside the sensor.
