Working principle: Nozzle throttling principle of measuring principle is based on fluid mechanics, fluid-filled with pipes, when they flow through the pipe nozzle, the velocity of flow in the nozzle to form local contraction, accelerated to flow, static pressure is reduced, and the pressure drop is produced before and after the nozzle or differential pressure, the greater the flow medium traffic, in the greater the nozzle pressure difference of before and after, So the fluid flow can be measured by measuring the pressure difference.
Working characteristics: (1) simple structure, convenient installation; (2) The pressure loss of the nozzle is smaller than that of the orifice plate, and the length of the straight pipe is also short; ③ No real flow verification, stable performance; (4) high temperature and high-pressure resistance, impact resistance; The corrosion resistance is better than the hole plate, long life; High precision, good repeatability, stable outflow coefficient; The circular arc structure design can measure all kinds of liquid, gas, steam and all kinds of dirty media; ⑧ Overall forging processing technology, high cost.
