Analysis of Orifice Plate Flowmeter Application 

      In the field of industrial flow measurement, the orifice plate flowmeter, as one of the long-standing differential pressure flowmeters, still holds an important position in industries such as petroleum, chemical engineering, and power due to its simple structure, stability, reliability, and wide applicability. This article delves into its core application scenarios and technical advantages to assist users in making informed selections.

 1. Oil and Gas Industry: A Reliable Choice for High-Pressure and High-Temperature Environments

    In the processes of oil and gas extraction, transportation, and refining, the orifice plate flowmeter demonstrates unique advantages:

✔ Long-distance pipeline natural gas measurement (compliant with AGA/ISO standards)

✔ Crude oil trade handover measurement (high-precision grade up to 0.5)

✔ High-temperature oil measurement in refineries (pressure resistance up to 42 MPa, temperature resistance over 400°C)

2. Chemical Industry: An Economical Solution for Corrosive Media

   For complex media such as acids, alkalis, and organic solvents:

✔ Use of Hastelloy/tantalum orifice plates to resist corrosion

✔ Integrated wedge design to prevent clogging by viscous liquids

✔ No power requirement, suitable for explosion-proof areas

Advantage: Maintenance cost is only 1/3 of that of electromagnetic flowmeters, especially suitable for large pipe diameters.

3. Power Industry: The Classic Choice for Steam Measurement

   In the thermal systems of thermal power plants: 

✔ Main steam/reheat steam flow monitoring

✔ Feedwater flow control (used in conjunction with condensate tanks)

✔ Compliant with ASME PTC6 performance testing standards

Technical highlights: A specially designed nozzle orifice plate can reduce pressure loss to less than 1.5%.

4. Municipal and environmental fields: Large pipe diameter water metering

   ✔ Inflow and outflow metering of wastewater treatment plants (pipe diameters above DN3000)

✔ Heating network water flow monitoring

✔ Water conservancy project water diversion metering

Innovative application: Equipped with an intelligent differential pressure transmitter to achieve 4-20mA + HART digital output.

5. Selection and application points

    Medium adaptability: Not suitable for slurries with solid particles exceeding 5%

Installation requirements: Ensure a straight pipe section of 10D before and 5D after

Economic analysis: Higher cost for small diameters, significant cost-effectiveness for DN200 and above
