Detailed Product Description: | Flue gas flow parameters, specifications: DN50-DN5000 (mm); plug-in: DN500-DN5000 (mm); 2, measurement accuracy: ± 6.0%; Repeatability: ± 0.1%; range of degrees: volume flow : 10:1; mass flow: 8:1; 4, working pressure: average rate pipe to propose functional: ≤ 20MPa; average rate of the proposed type: ≤ 10MPa; to 5 fluid temperature: ≤ 450 ° C; 6, medium Viscosity: ≤ 30CP (heavy oil equivalent); 7, Material: rate of three valves: various grades of stainless steel (optional); main pipe flange: stainless steel or carbon steel (optional); flue gas flowmeter The details; flue gas flow meter, also known as the average rate of flow and ideal alternative orifice its installation is simple, small pressure loss, high strength against wear affect no leakage characteristics. Flue gas flowmeters can be widely used in industrial and mining enterprises, blast furnace gas, compressed air, steam and other liquids, gas flow measurement. The unique internal secondary average structure, provides high accuracy (of reading ± 1%) and high repetition (± 0.1%). 2 outer layer of shock tube with a single piece of material manufacture made no welding, highest intensity compared to similar products by the dual structure welded naturally, but also to facilitate the selection of high temperature, corrosion-resistant materials. a honeycomb hexagonal stable structure, and the resulting stream of unique distribution shape, to ensure the stability of the low-voltage signal, the differential pressure is higher than the similar products, to improve the turndown ratio. b suitable for square or rectangular pipes. c For similar products in measuring the dirty media inevitably clogging problems online can pull out the type or provide manual and automatic purge program and device implementation does not shutdown maintenance. d were speed tube + three valves + temperature and pressure compensation + transmitter, composed of integrated structure, easy to use. e flow coefficient drift, long-term stability. f exclusive intuitive resonance checking to ensure long-term stable operation. g pressure loss, low consumption, energy saving effect is remarkable supporting the use of flue gas flowmeter output differential signal, and the measurement of differential pressure instrumentation can accurately measuring He-shaped pipe, rectangular pipe of a variety of liquids, gases and vapor (superheated steam and saturated steam). Test pipe size ranges from 20MM-3000MM. Flue gas flow meter in the power industry (nuclear industry) chemical industry, petrochemical and metal smelting industries sector Bank of China to the successful use of it applies to: 1, gas transportation and liquids transportation, energy research, steam boiler heat rate pump efficiency, gas compressor efficiency and fuel consumption, process control: input and output, ratios, balance; cooling water or air, steam heating. 4, the chemical industry in the feed: flue gas flowmeter working principle when the fluid flow through the flue gas flow meter probe in the front portion thereof slightly above generates a high pressure distribution, the pressure of the high-pressure distribution pipe hydrostatic. According to the principle of Bernoulli's equation, the fluid flow through the probe speed, the rear of the probe to generate a low-voltage distribution, a low-pressure distribution of the pressure slightly lower than the static pressure of the pipeline. Fluid from the rear of the probe after the probe flow partial vacuum is generated vortices appear on both sides of the probe. The average rate of the cross-sectional shape of the flow probe, a rough surface condition and the low-pressure to take the position of the press hole is to determine the key factors of the performance of the probe. Stable and accurate low voltage signal to play a decisive role in the accuracy and performance of the average rate of the probe. Flue gas flowmeter average rate of flow probe can be accurately detected by the average velocity of the fluid produced by the average differential pressure. Flue gas flow meter speed flow probe, multi arranged according to certain criteria to take pressure hole area of ??low pressure, it possible to accurately measure the average flow rate. Flue gas flow meter advantage of high accuracy (compared with the orifice plate) stability of the flue gas flow meter accuracy ± 1%, the stability of ± 0.1%, it is able to maintain a very stable long-term output of the differential pressure signal to ensure that the output differential signal of pipeline flow mapping relationship. This is because of the wear and tear during use, corrosion and oil adhered dust or the like factors have little influence on the flue gas flowmeter coefficient, but these factors make the flow coefficient of the orifice plate is increased, and will be increased to more than 20% by This generated error will also reached above 20%. We can see the long-term stability of the accuracy of the flue gas flow meter. Reasonable design, easy installation, economic flue gas flow meter light weight, easy installation and removal, without lifting tools product line, continuous flow can be measured pipeline installation or removal - No, no parking due to the flue gas flowmeter, light weight, easy installation and removal, so this can save you a considerable installation costs. For example: 200mm diameter pipeline installed flowmeter flowmeter only a length of 150mm flue gas weld, orifice plate 2 Total length 1200mm length of the weld. In terms of working hours, the installation of a flue gas flowmeter only 1.5 man-hours, while installing an orifice needs 12 hours of work is conducive to the piping layout flue flowmeter is applicable not only to the circular pipes, is also applicable to the rectangular pipe and embedded in the any depth below the surface of the pipe. Flue gas flowmeter downstream straight pipe length requirement is much lower than the orifice plate, when installed in the elbow behind can still get close to two times the diameter at a stable, high accuracy, which is a flue gas flowmeter unique advantages to the pipeline, especially large diameter pipe layout design brings a great deal of flexibility, saving the cost of a small pressure loss, less energy loss, permanent pressure loss is a loss of power, the flue gas flow meter permanent pressure loss accounted for only differential pressure of 2 to 15%, while the permanent loss of the orifice in general have to be accounted for 40 to 80% of the differential pressure, can be seen from the permanent pressure loss of the flue gas flowmeter pressure loss is much smaller than the orifice, with The significant increase of the diameter of the flue gas flow meter permanent pressure loss is negligible. For example: the use of flue gas flow meter 1000mm diameter pipeline, only a few hundred dollars a year of energy loss, when the use of orifice plate, the energy losses of up to 2 million yuan a year, which today is striving to conserve energy, strong views.
