Brief introduction Differential pressure transmitter induction of flue gas dynamic pressure and static pressure, dynamic pressure and static pressure and pressure difference of gas flow velocity, flow large pressure difference is also large. When there is no velocity pressure 0. There fore, according to the calculated from the pressure difference, flue gas constant and the absolute temperature of flue gas, the pitot tube correction coefficient to calculate the velocity. In the flue gas velocity measurement method, using Pitot tube anemometer velocity measurement is a classical method of measuring; due to s type pitot pressure hole with a larger opening, not easy to be particulate clogging, easy to high pressure gas purge, maintain cleanliness of the pressure hole opening, so for the continuous measurement of effect is good. Features The flow rate, dynamic pressure, static pressure and temperature of the flue gas can be measured in real time, and the output of the signal is 4~20mA. Measurement accuracy, high reliability, can be long-term continuous work Automatic zero calibration function The integral structure can be quickly disassembled, which is convenient for packing, transportation and carrying. The surface of pitot tube are done in the special treatment, can effectively prevent corrosion of flue gas and reducing dust adhesion Imported high precision and high stability micro pressure sensor, can be measured as low as 2m/s flow rate RS485 interface can be used to debug software to facilitate the parameter configuration. Optional split type display control unit or ACL2020 hand operator, set the parameters Technical parameter Insert length: 1500mm or custom length Measurement range: (2 ~ 30) m/s Accuracy: ≤ 2% FS Check frequency: 12 months Power requirements: DC24V/5A Working environment: temperature (-20 ~ 45)℃ relative humidity ≤ 90% Medium temperature: (0 ~ 300)℃
