Description of the characteristics of the throttle type differential pressure flowmeter

Main features of throttling differential pressure flowmeter
The most common throttling standard orifice plate structure is easy to copy, simple, firm, stable and reliable, long service life and low price.
The throttling DPF has a wide range of applications, and no flow meter has been compared to it. All single-phase fluids, including liquid, gas and steam, can be measured. Some mixed phase flows, such as gas-solid, gas-liquid, liquid-solid, etc. can also be applied. Generally, the pipe diameter and working state (pressure, temperature) of the production process are all products. .
The detection and differential pressure display instruments can be separated from different production plants for easy specialization to form economies of scale, and their combination is very flexible and convenient.
Test pieces, especially standard ones, are used worldwide and are recognized by international standards organizations. The experimental research conducted on 尉 standard type test pieces is international. Other flow meters generally rely on individual manufacturers or research groups, so the depth and breadth of their research are not the same. From the time point of view, the standard type of test piece has not changed since it was determined by the International Organization for Standardization in the 1930s. The accumulation of research data and production practices is extremely rich, and its application range is not comparable to that of a type of flow meter.
For the above reasons, the standard throttle DPF can be used without real-flow calibration, and it is also the only one in the flowmeter.
One.
It is currently the most widely used in both types of throttling and dynamic heads. Throttle has developed more than 20 varieties, and there are still new varieties developed, more mature to standard development, ISO has a technical committee responsible for this work. The dynamic pressure head type is represented by a constant velocity tube flowmeter. It has developed rapidly in recent years. It is the main type of plug-in electromagnetic flowmeter, and its dosage is increasing rapidly.
