SLDL2525 Split type ultrasonic level gauge

Working Principle
SonicScan ultrasonic level meter emits ultrasonic pulse, the ultrasonic signal is reflected back from the surface of the measured medium. Some of the transmitted echoes are received by SonicScan and converted into electrical signals. The ultrasonic pulse is propagated by sound wave velocity, and the time interval from transmitting to receiving ultrasonic wave pulse is proportional to the distance from the sensor to the surface of the measured medium. The relationship of this distance value S, sound velocity C and transmission time T can be expressed by a formula£ºS=C×T/2.
Product Feature
  • Due to the use of advanced microprocessors and unique SonicSmart echo processing technology, ultrasonic level meter can be used in a variety of complex conditions.
  • The sensor has a built-in temperature sensor which can realize real-time temperature compensation of the measured value.
  • The ultrasonic sensor adopts the patented technology of the best acoustic matching so that its transmit power can be radiated more efficiently and the signal strength can be increased to achieve accurate measurement.
  • The false echo learning function enables the meter to correctly confirm the true echo and obtain the accurate measurement results under the condition of multiple false echoes.
  • Multi-language support (including Chinese), echo, false echo visual display, easy to analyze and debug by maintenance personnel.
  • Protection grade IP68
  • Support Hart,Modbus, Profibus PA, Foundation Fieldbus¡¢GPRS/CDMA remote, Bluetooth, etc.
