Gas Flowmeter

Gas Flowmeter mainly used in coke oven gas, blast furnace gas, the measured furnace gas, mixed gas and other gas media with such media containing impurities, dust, fouling, low pressure and low flow rates. Gas Flowmeter capacitive force sensor using the new sensor, dirt-resistant, high sensitivity, easy to install maintenance-free, accurate measurement of differential pressure to solve the shortcomings of traditional easy to plug the hole to take pressure, can completely replace the differential pressure flowmeter. Pressure loss is small for large pipes, special pipes, low pressure, vacuum pipe, plug-in structure, easy to install. Name the gas flow meter for medium coke oven gas, producer gas, blast furnace gas, water gas flow measurement diameter (DN) DN15 ~ DN6000mm to a larger nominal 0.6 ~ 4MPa (refer to the connection flange nominal, non-media work pressure) conditions Temperature -20 ~ +200 ℃ (higher temperatures please contact the factory) Accuracy ± 0.2 ~ ± 1.5% FS range 1:3 (± 0.2%), 1:10 (± 0.5%), 1:15 (± 1.5%) Housing Material Carbon Steel; stainless steel; 3.6VDC power supply built-in lithium battery (available for two years); external supply 24VDC; 4 ~ 20mA output signal wire; pulse 0 ~ 1000HZ; RS485 protection IP65 ; IP67 proof mark intrinsically safe ExiallCT4; flameproof ExdllCT4 first table shows the cumulative flow; instantaneous flow; percentage of full scale; pressure conditions; working temperature; fault detection pipe flange connection (DN15-300mm); insert Formula (DN100-N6000mm to greater). Installation requirements can be horizontal, vertical installation; straight pipe should meet before the previous 10D 5D (D DN) special connection thread type; wafer; Online removable; (please specify connection require special ordering) [Gas Flowmeter Features] · The whole instrument in the design with no moving parts, easy installation maintenance Adopting advanced third-generation capacitive force sensor, reliable performance, high precision, sensitivity; small · pressure loss of only one standard orifice / about 2 △ P · dirt-resistant, non-blocking, anti-vibration, electromagnetic interference, anti-impurity capacity particularly strong, alternative differential pressure flowmeter · can choose a variety of corrosion and high temperature resistance material (such as Hastelloy, Titanium etc.) · sake sealing machine can do no dead (welding), without any leaks, can withstand high pressure 42MPa · Meter features self-test procedure Symptom glance · sensor is not in contact with the measured medium, there is no spare parts wear, safety and reliability · may make use of dry calibration method which uses weights hanging weight method. · One Touch Calibration can be done with a variety of installation options, such as selecting the online plug-in, low installation costs · With integrated temperature and pressure compensation, direct output quality or standard side * with optional low-cut, linear correction , filtering time can accurately measure a variety of selectable · temperature, high temperature of 500 degrees, low of -200 degrees condition of gas, liquid flow · accurate measurement accuracy of 0.2%, repeatability, generally 0.05 to 0.08% Measuring fast · according to actual needs replacement baffles (target sheet) to change the flow range · Low power battery live shows, online direct reading indication, the display screen can be read simultaneously instantaneous and cumulative flow and percentage bar graph · Installation simple, easy to maintain * A variety of output forms, various parameters can be remote · strong anti-vibration, pulsation can be measured within a certain range of gas flow meter installed [Note] does not allow direct measurement of the flow meter before and after the installation of the pipe ends valves, elbows and other parts of fluid flow pattern changed dramatically, and the front and rear, if you need to install valves, elbows and other parts of the pipeline on the front should also try to ensure that the meter straight pipe length, straight pipe sections required before 10D, the 5D, the completion of the new technology pipeline, should be installed after the initial purge flowmeter. ◆ Gas Flowmeter due process requirements can be mounted vertically, the measured medium flow by the bottom, but also from top to bottom, but should the supplier when ordering; ◆ insert the flowmeter installation, the short tube and flange must ensure that the fluid force facing the target chip surface, welding short pipe height 100mm (the distance from the pipe wall to the flange sealing surfaces) ◆ completion of the process for the new pipeline, should be carried out when the initial purge welded to the pipe after re-installation of a gas meter; ◆ measuring tube outer wall of the arrow is the measured medium flow; ◆ Gas meter housing must be grounded, the factory should explain the absence of ground conditions;
