Product Description:
Standard nozzle, also known as welding nozzle. The measurement principle is: when the fluid filled with the pipe flows through the throttling device in the pipe. The flow beam will form a local contraction at the throttling part of the throttling device, so that the flow rate increases, the static pressure is low, and the pressure drop is generated before and after the throttling part, that is, the pressure difference. The greater the flow rate of the medium flow, the greater the pressure difference generated before and after the throttle part, so the standard nozzle can measure the size of the fluid flow by measuring the pressure difference. Standard nozzle flow meter is based on the law of energy preservation and the law of flow continuity, and is used with the differential pressure transmitter to measure the flow of liquid, steam, gas, standard nozzle is widely used in petroleum, chemical industry, metallurgy, electric power, light…
