Venturi meter is used to measure the flow of single-phase stabilized fluid in closed pipelines. It is often used to measure the flow of air, gas, gas, water and other fluids.

1. Nominal diameter: 50mm is less than or equal to 1200mm, and coarse casting shrinkage section: 100mm is less than or equal to 800mm; Machining contraction section: 50mm is less than or equal to 50mm; Coarse welded iron plate contraction section: 200mm is less than or equal to 1200mm;

2。 The diameter of the throttle is greater than that of beta: 0。3 is less than or equal to 0。75 coarse casting shrinkage segment: 0。3 is less than or equal to 0。75; The machining shrinkage section 0。4 is less than or equal to 0。75; Coarse welded iron plate contraction section: 0。4 is less than or equal to beta;

3. Reynolds number range: 2 x 105 is less than or equal to 2 x 106, and the contraction section of coarse casting: 2 times 105 is less than or equal to 2 times 106; Machining contraction section: 2 x 105 is less than or equal to ReD or 106; Coarse welded iron plate contraction section: 2 x 105 is less than or equal to 2 x 106;
