HX-J seriesorifice plate flowmeterYesStandard orifice plateWith multiple parametersDifferential pressure transmitter(or differential pressure transmitter, temperature transmitter, etc.)Pressure transmitterA high range ratio differential pressure flow device composed of a pressure transmitter can measure the flow of gases, vapors, liquids, and induced gases. It is widely used in process control in fields such as petroleum, chemical, metallurgical, power, heating, and water supply.

1、 Advantages
1. Standard throttling components are fully functional and have been recognized by international standard organizations, and can be put into use without the need for actual flow calibration;
2. The structure is easy to replicate, simple, sturdy, stable and reliable in performance, and inexpensive;
3. Widely applicable, including all single-phase fluids (liquid, gas, steam) and some mixed phase flows;
4. The detection components and differential pressure display instruments can be produced separately by different manufacturers, facilitating specialized scale production.
2、 Technical parameters
1. Nominal diameter: 15 mm ≤ DN ≤ 3000mm 2, nominal pressure: PN ≤ 40MPa
3. Working temperature: -50 ℃ ≤ t ≤ 550 ℃ 4. Range ratio: 1:10 5. Accuracy: Level 0.5, Level 1
3、 Selection of required parameters
1. The diameter of the pipeline (diameter * wall thickness); 2. The medium measured by the orifice flowmeter; 3. The working temperature of the tested medium; 4. The working pressure of the tested medium (maximum pressure, minimum pressure, normal pressure); 5. The working flow rate of the tested medium (maximum flow rate, minimum flow rate, normal flow rate); 6. Viscosity of the measured medium
4、 Installation requirements
The installation and application of the throttling device are related to the following pipe sections and fittings: the first and second resistance pieces on the upstream side of the throttling element, the first resistance piece on the right side below the throttling element, the pipe section between the second resistance piece upstream and the first resistance piece downstream of the throttling element, and the differential pressure signal pipeline.
