The KSONIK III is an Ultrasonic Level Transmitter Capable of Measuring Two Separate Levels in Liquid or Solid Applications up to 195 ft. / 60 meters, or Flow Rates in all Types of Open Channel Flow Applications. The Unit is Available with Two 4-20 mADC Analog and Five (5) Relay Outputs. A System Can Consist of Up to Two Transducers and a Single Transmitter with the Transducer(s) Installed at the Top of a Silo or Tank, Facing Down Towards the material being Measured. The Transmitter's Microprocessor Simultaneously Fires an Electronic Pulse to the Transducer and Stars a Timer. The Transducer Converts this Electronic Pulse to an Acoustic Pulse, Which is Directed Toward the Surface of the Material Being Measured. When the Acoustic Pulse Contacts the Surface of the Material, Energy is Reflected Back to the Transducer, Which Converts This Reflected Energy Back to an Electronic Pulse. This Pulse is Sent Back to the Microprocessor, Which Stops the Timer and Determines the "Time of Flight" of the Signal. By Combining the Speed of Sound Through Air and the "Time of Flight" of the Pulse, the Microprocessor Accurately Determines the Level of the Product. Powerful Software Removes False Echoes From the Signal and Electronic Filters Remove Ambient Noise.
