Brief introduction
ACF-1-PZ integrated smart nozzle flow meter is differential pressure generator to measure the flow, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes. ACF -1PZ integrated nozzle flow meter has the features of high temperature and high pressure resistance, impact resistance, long service life, large measuring range, high measuring accuracy, low pressure loss, etc. These features all can be used for trade settlement. Compound use with differential pressure transmitter, it can measure the flow rate of liquid, steam and gas. It is widely used in petroleum, chemical industry, metallurgy, power, light industry, etc.
Measure theory
When fluid filled with pipe flow through the nozzle, the flow will form local contraction at the throttling area of the nozzle to accelerate the flow and reduce the static pressure, then there will be pressure drop also called differential pressure before and after the nozzle. The bigger of the medium flow rate, the bigger of the differential pressure, so we can measure the flow rate by measuring the differential pressure.

Features
- nozzle pressure loss is less than orifice, straight pipe length is short;
- circular arc form design, good abrasion resistance, flow stability, can measure liquid, gas, steam and smudgy medium;
- corrosion resistant performance is good, more suitable to measure single well natural gas and coal bed gas and other raw gas than the orifice plate;
- replace the nozzle, the measurement range can be adjusted within wide range, meet the changes needs of different stages of the single well production capacity;
- no real flow calibration, high precision, stable outflow coefficient;
- simple structure, convenient installation, safe and reliable, maintenance cycle is long, long service life;
- show the cumulative flow and transient flow, pressure, temperature at the same time
