Sultan Non-Contact Acoustic Wave Series

Sultan Non-Contact Acoustic Wave Series

The Sultan is a powerful non-contact Acoustic Wave transmitter for level, flow, positioning, and collision protection. This self-cleaning sensor requires zero maintenance and is ideal for measuring level of liquids, slurries, and solids. The combination of low frequency, high power, and signal processing (Adaptive Gain Technology) creates one of the world's most reliable level devices available on the market.


Principle of Operation

The transmission of high-powered acoustic waves ensures minimal losses through the environment where the sensor is located. Due to the high-powered emitted pulse, any losses have far less effect than would be experienced by traditional ultrasonic devices. More energy is transmitted hence more energy is returned. Advanced receiver circuitry is designed to identify and monitor low-level return signals even when noise levels are high. The measured signal is temperature-compensated to provide maximum accuracy to the outputs and display.
