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)
Annubar flowmeter 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.
Annubar Flowmeter(also called flute velocity-equalizing tube flowmeter) output for the differential signal, and measuring the differential pressure instruments, can accurately measure the circular pipe, rectangular pipe in a variety of liquids, gases and steam (superheated steam and saturated steam). The size of the pipeline under test range from 3/4 "- 3000. The pig (including nuclear industry) in the power industry, chemical industry, petroleum chemical industry and metal smelting industry has been successfully used in departments and so on, it is suitable for:
(1) the gas and liquid transportation;
(2) energy research, steam boiler thermal efficiency, pump efficiency, gas compressor efficiency and fuel consumption.
(3) process control, input and output, ratio/balance, cooling water or air, steam heating.
(4) material in chemical industry;
(5) load balancing: pump, compressor and cooler, filter;
Features:
1. High accuracy, good stability
Pig of plus or minus 1% accuracy, stability is plus or minus 0.1%, can maintain long-term differential pressure signal of the output is very stable.
2. The reasonable design
Pig, light weight, easy installation and disassembly, without lifting tool.
3. Conducive to pipeline layout
Pig is not only suitable for round pipe, also apply to the rectangular pipe and buried depth of any of the following pipes.
4. The pressure loss is small, less energy consumption.
5. Stable hexagonal honeycomb structure is produced by the unique shape of the distribution of a beam to ensure the stability of the low voltage signal, the differential pressure is higher than similar products, improve the range ratio.
6. Measuring smudgy medium for the similar products in the inevitable congestion, there are online can be pulled up or provide manual and automatic purging methods and devices, not achieve production maintenance.
7. Velocity-equalizing tube + 3 + + transmitter temperature pressure compensation valve group, composed of integrated structure, easy to use.
8. No flow coefficient, the long-term stability.
