Hangzhou Chunlai Technology CO., Ltd. products

The FLW-300 is based on the principle of the ultrasonic time difference method for gas flow rate measurement. The product adopts the innovative structure design of temperature, pressure and flow integration with simple installation and disassembly. It is used for flow rate measurement of boiler flue and chimney flue gas and is particularly suitable in the cases of a short straight pipe section, a low-speed flue of less than 5m/s, and a flue where it is not possible to increase the number of openings.

The FLW-100 uses a pair of ultrasonic transducers that alternately (or at the same time) send and receive ultrasonic waves. Velocity can be measured indirectly through the observation of ultrasonic wave propagation time difference between downstream and countercurrent in the medium. The flow meter meets the requirements of relevant national standards and can be used for real-time continuous measurement of flue gas temperature, pressure, velocity and flow rate in flue gas emission monitoring systems (CEMS).

PT-500 Split-type Temperature, Pressure & Velocity Monitor is designed for working condition of low flowrate (1m/s~5m/s). It employs high-precision micro differential pressure/static pressure sensor and special structure design of pitot tube. Combined with automatic calibration and purge technology, it can be widely applied in real-time and continuous flue gas measurement of temperature, pressure, velocity and flow.
