The nozzle flow meter is a differential pressure generation device for measuring flow, with a variety of differential pressure meters or differential pressure transmitters can measure the flow of various fluids in the pipeline.
Standard nozzle throttling device with differential pressure transmitter can measure the flow of liquid, steam, and gas, widely used in petroleum, chemical, metallurgy, electric power, light industry, and other sectors.
So what is the “difference between the nozzle flow meter and orifice flow meter”?
1. Nozzle flowmeter
Nozzle flowmeter is a differential pressure generation device for measuring flow, with a variety of differential pressure meter or differential pressure transmitter can measure the flow of various fluids in the pipeline.
Standard nozzle throttling device with differential pressure transmitter, can measure the flow of liquid, steam, gas, widely used in petroleum, chemical, metallurgy, electric power, light industry and other sectors.
Nozzle flowmeter advantages.
1. The standard nozzle has a long history, with a large number of various test data.
2. Nozzle flowmeter structure is simple and solid, no moving parts, long-term use of stable and reliable
3. A wealth of design and manufacturing and application experience, a high degree of standardization, can be without the need for real flow calibration.
4. The standard nozzle has reliable experimental data and perfect international and national standards. True and reliable measurement data, can be used as a trade settlement measurement meter.
Disadvantages of nozzle flowmeter.
1. More complex production and manufacturing, higher unit prices.
2. Nozzle flowmeter flow when the nozzle before and after the pressure difference is greater than a certain value, the flow through the nozzle is a fixed value, the measurement of high accuracy level.
3. Generally used as a standard instrument is more.
2. The orifice plate flowmeter
Orifice plate flowmeter is the standard orifice plate and multi-reference differential pressure transmitter (or differential pressure transmitter, temperature transmitter, and pressure transmitter) supporting the composition of the high range ratio differential pressure flow device, which can measure the flow of gas, steam, liquid, and natural gas.
Orifice flowmeter advantages.
1. High-cost performance. Standard orifice plate has a long history of international and national standards and calibration procedures and a large number of test data, without real flow calibration.
2. Orifice plate flowmeter flow measurement has a certain range, no moving parts, and the price is more affordable.
3. Measurement data true and credible, can be used as a trade settlement measurement table.
Disadvantages of the orifice plate flowmeter.
1. Orifice plate sharp edges of wear, dirt, and other factors will affect the accuracy of measurement.
2. The calibration cycle is shorter 6-12 months.
3. The pressure loss is large, and large diameter due to the orifice plate before and after the pressure difference is difficult to measure, resulting in the accuracy of the orifice plate flowmeter level will not be very high.
