Nozzle flow meter is to measure flow differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes. Standard nozzle throttling device with differential pressure transmitter, can measure the rate of flow of liquid, steam, gas, widely used in petroleum, chemical, metallurgical, power, light industry and other departments.

General situation of

When the throttle device in the piping of the fluid flowing through a pipe, the beam will be local contraction at the throttling of the throttle device, so that the flow velocity increases, the static pressure is low, so the throttling parts before and after the pressure drop is produced, the pressure difference, the greater the flow of medium flow, in the front and rear of the throttling parts the greater the pressure difference, so the standard nozzle can be measured by the size of the pressure difference to measure fluid flow. This kind of measurement method based on the energy conservation law and the law of flow continuity as a benchmark. Intelligent throttling device (standard nozzle) is integrating flow, temperature and pressure detection, temperature, pressure, and can automatically compensate a new generation of flowmeter, the orifice meter adopts the new technology of advanced computer technology and micro power consumption, strong function, compact structure, simple operation, easy to use.
