Nozzle flowmeters are widely used in daily life, and nozzle flowmeters are mainly used to measure the flow of liquid, steam and gas, and are mainly used in the measurement of petroleum, chemical, metallurgy, electric power, light industry and other departments. Then let’s talk about the installation structure of the nozzle flowmeter.
The nozzle flowmeter has two structures of split installation and integrated installation.
1. The split installation of the nozzle flowmeter is composed of independent nozzle device, differential pressure, pressure, temperature transmitter, flow calculator, globe valve and other parts. The connection of the impulse pipe between the nozzle flow sensor and the differential pressure transmitter is done by the user.
The nozzle flow sensor only provides the nozzle part of the differential pressure signal, and does not provide the differential pressure transmitter and the flow calculation display part. The output signal is the pressure difference formed by the fluid before and after the throttling part. The nozzle flow sensor and the differential pressure transmitter together form the nozzle flow transmitter, which outputs a 4-20mA electrical signal representing the magnitude of the differential pressure signal. The flow calculation and temperature and pressure compensation are configured by the user.
2. One-piece installation means that the differential pressure transmitter and the nozzle have been connected into one body when the product leaves the factory. After the user purchases the one-piece nozzle, there is no need to connect the pressure pipe when using it. The integrated installation of the nozzle flowmeter is composed of an intelligent display instrument and a nozzle device. One-piece installation comes with high-quality differential pressure sensor, pressure sensor, thermal resistance temperature sensor.
Using a large-screen LCD to display the cumulative flow, instantaneous flow, instantaneous pressure, and instantaneous temperature values on the same screen, no manual switching is required. 4-20mA two-wire instantaneous flow output. The intelligent display instrument not only automatically adapts to the range of the differential pressure sensor, but also has various compensation coefficients.
The above is the installation structure of the nozzle flowmeter, which can help play a certain role in the installation of the nozzle flowmeter.
