Orifice flowmeter is a high range ratio differential pressure flow device composed of a standard orifice plate and a multi parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter, and pressure transmitter), which can measure the flow of gases, steam, liquids, and other gases.
1. High precision to wide range ratio
① Orifice flowmeter has high measurement accuracy and can achieve relatively accurate flow measurement under conventional usage conditions. Its accuracy can generally reach ± 1% or higher (such as the high accuracy of intelligent orifice flowmeter can reach ± 0.075%).
② The range ratio of orifice flowmeter is wide, which can adapt to the measurement needs of different flow rates.
2. High reliability and stability
① The structure of orifice flowmeter is simple, without movable mechanical components, therefore it has high reliability and stability. It is not easily affected by changes in fluid media and external interference, and long-term use is not prone to mechanical failure.
② Orifice flowmeter can work stably for a long time and is suitable for occasions that require long-term monitoring of flow rate.
3. Easy installation and maintenance
① The installation of orifice flowmeter is relatively simple, just connect the orifice pipe fittings to the fluid pipeline. Due to the compact structure of the orifice flowmeter, it does not take up too much space and can be installed in smaller spaces,
② The maintenance cost of orifice flow meters is relatively low, generally only requiring regular cleaning and calibration. This reduces the operational costs for users.
4. Strong adaptability and wide measurement range
① Orifice flow meters are suitable for flow measurement of various fluid media, including liquids, gases, and vapors. According to different media, different materials of orifice flow meters can be selected to adapt to different working conditions.
② Orifice flowmeter can measure fluid flow at different temperatures, pressures, and flow rates, with a wide measurement range.
5. Intelligence and multifunctionality
① Modern orifice flow meters often have intelligent features, such as using imported monocrystalline silicon intelligent differential pressure sensors, high precision, and complete self diagnostic functions.
② The intelligent orifice flowmeter can also achieve programmable range adjustment and display functions such as cumulative flow rate, instantaneous flow rate, pressure, temperature, etc. In addition, it also has online and dynamic full compensation functions, as well as multiple communication interfaces.
6. Strong ability to withstand pressure
Orifice flowmeter can withstand a certain pressure within a certain range and is not prone to malfunction due to pressure changes. At the same time, its pressure bearing capacity can be enhanced by selecting orifice plates of different materials and increasing their thickness. This makes the orifice flowmeter suitable for flow measurement under high-pressure conditions.
In summary, orifice flowmeter has the characteristics of high precision, high reliability, easy installation, low maintenance cost, strong adaptability, small flow resistance, intelligence and multifunctionality, and strong pressure resistance. Widely used in process control and measurement in fields such as petroleum, chemical, metallurgy, electricity, heating, and water supply.
