Orifice plate 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). It can measure the flow of gas, steam, liquid, and lead, and is widely used in process control and measurement in the fields of petroleum, chemical, metallurgy, power, heating, water supply, etc. The throttling device, also known as the differential pressure flowmeter, consists of a primary detection element (throttling element) and a secondary device (differential pressure transmitter and flow display instrument), which are widely used in gas applications. Flow measurement of steam and liquid. It has a simple structure, easy maintenance, and stable performance.
Manufacturer of intelligent orifice flowmeter
Applicable occasions: This orifice flowmeter is suitable for a wide range of measured media, and can be used for flow measurement of almost all gases, vapors, and liquids, with a wide range of pipe diameters; Can withstand high temperature and high pressure. The flow range can be changed on site by setting the range of the differential pressure transmitter. It is easy to use, operate, and master, and requires minimal daily maintenance.
Throttling components: standard orifice plate, standard nozzle, long diameter nozzle, 1/4 circular orifice plate, double orifice plate, eccentric orifice plate, circular orifice plate, conical inlet orifice plate, etc. Pressure tapping devices: ring chamber, pressure tapping flange, clamping ring, pressure pipe and other connecting flanges (national standards, various standards and flanges of other design departments), fasteners. Measurement tube.
Installation requirements for orifice flow meters: The requirements for straight pipe sections are generally 10D in the front and 5D in the back. Therefore, when selecting an orifice flow meter, it is necessary to choose a flow meter suitable for on-site industrial and mining conditions.
The fluid filled in the pipeline, when passing through the throttling device inside the pipeline, will cause local contraction of the flow beam at the throttling element of the throttling device, thereby increasing the flow velocity.
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 gas, steam, liquid, and natural gas. Widely used in process control and measurement in fields such as petroleum, chemical, metallurgy, electricity, heating, and water supply. Orifice flow meters are widely used in various fields of the national economy, such as coal, chemical, transportation, construction, textile, food, medicine, agriculture, environmental protection, and people’s daily lives. They are an important tool for developing industrial and agricultural production, saving energy, improving product quality, enhancing economic efficiency, and management level. They occupy an important position in the national economy. In process automation instruments and devices, flow meters have two main functions: as detection instruments for process automation control systems and as total quantity meters for measuring material quantities.
advantage
- 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;
- The structure is easy to replicate, simple, sturdy, stable and reliable in performance, and inexpensive;
- Widely applicable, including all single-phase fluids (liquid, gas, steam) and some mixed phase flows. The diameter and working state (temperature, pressure) of the general production process can be measured;
- The detection components and differential pressure display instruments can be produced separately by different manufacturers, facilitating specialized scale production.
