1. Introduction to Orifice Flow Meter: It can only be beneficial. Orifice flow meter 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 gas, steam, liquid, and natural gas. The following introduces the relevant characteristics of orifice flow meters for your reference.

1. Scope of application of orifice flowmeter: 1. nominal diameter: 15 mm ≤ DN ≤ 1200mm

2. nominal pressure: PN ≤ 10MPa

3. working temperature: -50 ℃ ≤ t ≤ 550 ℃

4. range ratio: 1:10, 1:15

5. accuracy: level 0.5, level 1

2. Characteristics of orifice flowmeter: ▲ The throttling device structure is easy to replicate, simple and firm, with stable and reliable performance, long service life, and low price.

. ▲ Orifice plate calculation adopts international standards and processing ▲ It has a wide range of applications, all single-phase flows can be measured, and some mixed phase flows can also be applied. The standard throttling device does not require real flow calibration and can be put into use. The installation of the integrated orifice plate is easier, without the need for pressure pipes, and can be directly connected to differential pressure transmitters and pressure transmitters. Intelligent features ▲ Adopting imported monocrystalline silicon intelligent differential pressure sensor ▲ High precision, perfect self diagnostic function ▲ Intelligent orifice flowmeter with programmable range adjustment. ▲ It can display cumulative flow rate, instantaneous flow rate, pressure, and temperature simultaneously. ▲ In addition to online and dynamic full compensation functions, it also has self diagnosis, self setting of quantities and instructions. ▲ Equipped with multiple communication interfaces ▲ High stability ▲ Wide range, greater than 10:1 intelligent technical indicators ▲ High precision: ± 0.075% ▲ High stability: better than 0.1% FS/year ▲ High static pressure: 40MPa ▲ Continuous operation for 5 years without calibration ▲ Neglected temperature and static pressure effects ▲ Anti high overpressure

III. Orifice flowmeter design style: The fluid flows through the throttling device in the pipeline, causing local contraction near the throttling element, increasing the flow rate, and generating static pressure difference on both sides upstream and downstream. Under the condition of known parameters, the relationship between differential pressure and flow rate can be derived purely based on the principle of flow continuity and Bernoulli equation, and the flow rate can be obtained. The throttling device of the orifice flowmeter has a simple and sturdy structure, stable and reliable performance, long service life, and low price. It is a commonly used flow measurement instrument in industry. The entire processing process adopts international standards and undergoes strict inspection and testing. Users can use it with confidence after purchase. This flowmeter has a wide range of applications. All single-phase flow rates can be measured, and some mixed phase flows can also be measured using this product. The orifice flowmeter increases the flow rate and reduces the static pressure, resulting in a pressure drop before and after the throttling element, that is, a pressure difference. The larger the flow rate of the med
