Nozzle flowmeter is a widely used differential pressure flowmeter, which is mainly used to measure the flow of various fluids in pipelines. It has the advantages of long history of use, high degree of standardization, authentic measurement data, and simple and firm structure. The manufacturing cost of the nozzle flowmeter is relatively high, so there are generally more standard devices. Nozzle flowmeters and orifice flowmeters are both differential pressure flowmeters, with similar principles and uses, the main difference being energy saving and accuracy levels. Let’s take a look at the nozzle flow meter.
1. Characteristics of Nozzle Flow Meter
Nozzle flowmeter is a differential pressure generating device for measuring flow. It is mainly used to cooperate with various differential pressure gauges or differential pressure transmitters to measure the flow of various fluids in pipelines. It is widely used in petroleum, chemical industry, metallurgy, electric power, and light industry. and other departments.
1. Advantages of nozzle flowmeter
The nozzle flowmeter has a long history of use, has a large amount of test data and perfect international and national standards, has rich experience in design, manufacture and application, and has a high degree of standardization. It does not need to perform real-flow calibration, and the measurement data is true and credible; in addition, the nozzle flowmeter Simple and solid structure, no moving parts, stable and reliable for long-term use.
2. Disadvantages of nozzle flowmeter
The main disadvantage of the nozzle flowmeter is that the production is more complicated and the cost is higher; in addition, in the process of use, when the pressure difference before and after the nozzle is greater than a certain value, the flow through the nozzle is a fixed value, and the measurement accuracy level is high, so the general It is often used as a standard device.
