1. Illustration of Electromechanical 2022- Pressure Measurement Method of Orifice Flow Meter

Illustration of Electromechanical 2022- Pressure Measurement Method of Orifice Flow Meter: Orifice flow meter is a commonly used flow measurement instrument, and its pressure measurement method is the key to ensuring measurement accuracy. The pressure measurement methods of orifice flowmeter mainly include corner connection pressure measurement, flange pressure measurement, and radial distance pressure measurement. The following is a detailed illustration of these three pressure measurement methods:

1. Corner pressure measurement includes drilling pressure measurement and ring chamber pressure measurement. This method is beneficial for shortening straight pipe sections and improving measurement accuracy. Drilling pressure measurement: Features: Suitable for pipe diameters of DN400-DN3000. Pressure requirements: The distance between the axis of the upstream and downstream pressure tapping holes and the upstream and downstream end faces of the orifice plate should be equal to 1/2 of the diameter of the pressure tapping hole. The diameter of the pressure tapping hole should be 4-10mm, and the diameters of the pressure tapping holes on the upstream and downstream sides should be equal. The axis of the pressure tapping hole should intersect perpendicularly with the axis of the pipeline. Diagram: Ring chamber pressure measurement: Features: Suitable for pipe diameters of DN50-DN400. Pressure tapping method: The pressure tapping is carried out through the ring chamber structure to ensure the uniformity and stability of the tapping hole. Diagram:

2. Characteristics of flange pressure tapping: It has the characteris

tics of easy processing, easy installation and cleaning, but the accuracy is lower than that of corner joint pressure tapping, suitable for pipe diameters of DN50-DN1000. Pressure requirements: The distance between the axis of the pressure tapping holes on the upstream and downstream sides and the end faces on the upstream and downstream sides should comply with the specifications. The axis of the pressure tapping hole should intersect perpendicular to the axis of the pipeline, and the diameters of the pressure tapping holes on the upstream and downstream sides should be equal. Diagram:

III. Characteristics of radial pressure measurement: The pressure measurement point is fixed and suitable for pipe diameters ranging from DN50 to DN1000. Pressure measurement method: The pressure is taken through a fixed position pressure hole to ensure the stability and accuracy of the measurement. Diagram: In summary, the pressure measurement method of orifice flowmeter can be selected based on the requirements of pipe diameter and measurement accuracy, including corner joint pressure measurement (including drilling and ring chamber pressure measurement), flange pressure measurement, or radial distance pressure measurement. In practical applications, appropriate pressure measurement methods should be selected based on specific working conditions and measurement requirements to ensure measurement accuracy and stability.

2. Types and principles of flow meters

Types and principles of flow meters Flow meters are instruments used to measure fluid flow in pipelines or open channels. There are many types of flow meters, which can be divided into multiple types according to different measurement principles and structures.『SILVER Official Website SERVICE』
