Comparison of advantages and disadvantages between nozzle flow meters and orifice flow meters

Abstract: The comparative information on the advantages and disadvantages of nozzle flow meter and orifice flow meter is provided by excellent flow meter and flow meter manufacturers and quotation manufacturers. A nozzle flowmeter: The nozzle flowmeter is a differential pressure generating device for measuring flow. It can measure the flow of various fluids in the pipeline with various differential pressure gauges or differential pressure transmitters. The standard nozzle throttling device is used together with the differential pressure transmitter to measure liquid and steam. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the advantages and disadvantages of nozzle flowmeters and orifice flowmeters. 1. Nozzle flowmeter: The nozzle flowmeter is a differential pressure generating device for measuring flow. It can measure the flow of various fluids in the pipeline with various differential pressure gauges or differential pressure transmitters. The standard nozzle throttling device is used in conjunction with the differential pressure transmitter to measure the flow of liquid, steam and gas. It is widely used in petroleum, chemical, metallurgy, electric power, light industry and other departments. The advantages of the nozzle flowmeter: 1. The standard nozzle has a long history and has a large number of various test data. 2. The nozzle flowmeter has a simple and firm structure, no moving parts, and is stable and reliable for long-term use. 3. Rich experience in design, manufacture and application, The degree of standardization is high, and real flow calibration is not necessary. 4. Standard nozzles have reliable experimental data and perfect international and national standards. The measurement data is authentic and reliable, and can be used as a meter for trade settlement. Disadvantages of nozzle flowmeter: 1. The production and manufacture are more complicated, and the unit price is high. 2. When the flow rate of the nozzle flowmeter is greater than a certain value, the flow rate through the nozzle is a fixed value, and the measurement accuracy level is high; 3. It is generally used as a standard device. 2. Orifice flowmeter: Orifice flowmeter is a high-range ratio differential pressure flow composed of standard orifice and multi-parameter differential pressure transmitter (or differential pressure transmission, temperature transmitter and pressure transmitter). A device that measures the flow of gas, steam, liquid and natural gas. Advantages of orifice flowmeter: 1. High cost performance. Standard orifice plate has a long history, with international and national standards and verification regulations and a large number of test data, without real-flow calibration. 2. The flow measurement of the orifice flowmeter has a certain range, no moving parts, and the price is more affordable; 3. The measurement data is authentic and reliable, and can be used as a meter for trade settlement. Disadvantages of orifice flowmeter: 1. Factors such as wear and dirt on the acute edge of the orifice will affect the measurement accuracy. 2. The verification period is shorter than 6-12 months. 3. The pressure loss is large. When the diameter is large, it is difficult to accurately measure the pressure difference before and after the orifice plate, so the accuracy level of the orifice plate flowmeter will not be very high. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
