The integral orifice flow meter is a standard throttling device with the most specifications. It is widely used in various fluids, especially gas flow measurement. The structure of the orifice plate is different due to the pressure, diameter, and pressure taking method. The standard orifice plate can be divided into three types: corner connection pressure, flange pressure, and radial distance pressure.

Product features
The integral orifice flow meter has many advantages, but it is generally felt that the pressure taking line is laid in the field
Large volume, but also prone to leakage, blockage and other problems. In recent years, differential pressure transmitters have been made
Rapid development, not only compact size, and stable performance, convenient adjustment, so that
There is basically no need to adjust the zero point in the process of use. These advantages contribute to a body throttle type
Development and application of flowmeter (including orifice plate, annular orifice plate, nozzle, etc.).
Main technical parameters:
Nominal diameter (mm) : DN50 ~ DN1000
Nominal pressure (MPa) : ≤10
Ambient temperature: -20℃ ~ 55℃
Fluid medium temperature: -20℃ ~ +300℃
Function setting: it can be equipped with relevant instruments according to user’s requirements to realize signal remote transmission (with fieldbus function), intelligent compensation, display flow rate or mass flow rate, standard volume flow rate, etc.
Application:
Biotechnology
The 21st century will usher in the century of life sciences, and industries characterized by biotechnology will develop rapidly. There are many substances that need to be monitored and measured in biotechnology, such as blood and urine. The instrument development is extremely difficult, and there are many varieties.
Scientific experiments
The flowmeters required for scientific experiments are not only large in number, but also extremely diverse in variety. According to statistics, a large part of the more than 100 types of flowmeters are used for scientific research. They are not produced in batches and are sold in the market. Many scientific research institutions and large enterprises have set up special teams to develop special flowmeters.
Open the field
These areas are open flow channels, and generally need to detect the flow rate, and then calculate the flow rate. The physical principles and fluid mechanics foundations on which flow meters and flow meters are based are common, but the instrument principles, structures, and operating conditions are quite different.
Advantage:
(1) The most widely used orifice flowmeter has a solid structure, stable and reliable performance, and long service life;
(2) It has a wide range of applications, and there is no other type of flow meter comparable to it so far;
(3) The detection parts, transmitters, and display instruments are produced by different manufacturers, which is convenient for scale economic production.
