Summary 1:
throttling device, also known as differential pressure flowmeter, Orifice flowmeter contains (integrated orifice flow meter, standard orifice, annular orifice flow meter, integrated annular orifice flow meter)
Nozzle flow meter (integrated nozzle flow meter)can be divided according to function name gas flow meter, flue gas meter, steam flow meter, gas flow meter, compressed air flow meter, liquid flow meter.
Throttling coffret - nozzle flowmeter has many advantages, but generally feel pressure pipeline installation on site work is large, also easy to leak, congestion and other issues. Differential pressure transducer made by leaps and bounds in recent years of development, not only the small size, and stable performance, easy to adjust, in use process basically don't need to adjust the zero point. These advantages contribute to a body orifice flowmeter (including orifice plate, the annular orifice, nozzle, etc.) in the development and application. Nozzle flow meter is to measure flow differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes. Standard nozzle throttling device with differential pressure transmitter, can measure the rate of flow of liquid, steam, gas, nozzle flowmeter has a long history background, all kinds of test data is complete. Simple structure, no moving parts, stable and reliable long-term use, rich experience in design and manufacture and application. Doesn't need a high degree of standardization, solid flow calibration. Standard orifice has reliable experimental data and improve the international and national standards. In foreign countries and has its inherent in the huge domestic market, users are familiar with, data; Follow the international standard calculation and processing, use agile and convenient; According to relevant data of estimate of flow meter between 60% and 70% of the total consumption. It is widely used in petroleum, chemical, metallurgical, power, light industry and other departments.
