Kaidi KD KLSZ-G Liquid ultrasonic Flow Meter Flameproof for Thermal power plant
The wall-mounted ultrasonic flow meter uses the speed difference method as the principle to measure the liquid flow in the round pipe.
This series of meters adopts digital transmission, digital reception, digital analysis, digital output and other micro-power digital design technologies. The meters are accurate in measurement, reliable in operation, and more suitable for the needs of industrial sites.
The converter forms are: wall-mounted, panel-mounted, and integrated; the sensor forms are: plug-in, pipe segment, and external clamp.
Micro-power consumption and digital design: The whole machine adopts micro-power hardware and software design, and carries out digital transmission, digital reception and digital analysis of ultrasonic signals to achieve a comprehensive digital design. The power consumption of the whole machine is less than 0.3W. The power consumption of the battery-powered machine is only 0.2mW.
Excellent measurement and management functions: scientific analysis and calculation techniques are used in software design to ensure accurate measurement functions. In addition, a management function is designed. This series of instruments can check the operating data of the instruments at any time in the previous ten years at any time.
Flexible maintenance performance: The use of commutation adaptive technology enables this series of instruments to automatically eliminate the zero point error in the measurement process, and can replace the converter and sensor at will during the maintenance process, without affecting the measurement accuracy.
Chinese characterization technology: The data input and measurement process of the instrument display all Chinese characters, so that the operator can operate without using the manual.
Plug-in ultrasonic flow meter: can be installed and maintained without stopping production. Using ceramic sensors, use our company's special drilling device for non-stop production installation. Generally, it is a single channel measurement. In order to improve the measurement accuracy, three channels can be selected.
Pipe-segment ultrasonic flow meter: the pipeline needs to be cut and installed, but the production can be stopped for future maintenance. You can choose a single-channel or three-channel sensor.
Clamp-on ultrasonic flow meter: It can complete fixed and mobile measurement. Use special coupling agent (room temperature curing silicone rubber or high temperature long-chain polymer grease) to install, and the pipeline will not be damaged during installation.
