Overview
Product Features
1. Simple structure, easy to install;
2. The pressure loss of nozzle is smaller than orifice, with no effusion, requires a short length of straight pipe;
3. No need for real flow verification, stable performance;
4. High temperature, high pressure, impact and corrosion resistance;
5. Long life;
6. High accuracy, excellent repeatability, stable flow coefficient;
7. Measurable for liquid, gas, vapor and various dirty mediums;
8. Uses forging processing technology, the size of the throttle part is customized and produced by single piece, with higher manufacturing costs.
Operating Principle
Based on the throttling principles of fluid mechanics, fluid in pipeline flowing through the nozzle in pipes, the flow rate forms a local contraction in the nozzle, and accelerate the flow speed, reduce the static pressure, so in front and back of the nozzle will be a pressure drop or differential pressure, the greater flow of medium flowing, the larger pressure around the nozzle will be, so the size of the fluid flow can be measured by measuring the differential pressure.
