The Ultrasonic Point Level System 5600 Series is designed to non-invasively detect the presence or absence of liquid in a tube using Ultrasonic Technology to transmit and receive sound.  This could also be viewed as detecting the presence of bubbles in a tube or an Air Bubble Detector. There are no moving parts to the sensors. It is not dependent on the color, dielectric constant, density, viscosity of the liquid or the color, opacity and material of the tube.

The miniaturized electronics are built in the sensor. The sensors can be built to any type of tube to detect the presence of bubbles or Air-In-Line that range in size from 1mm to 19mm. Consult Sensaras for sensors requiring a larger tube size. There is no calibration or adjustment as each sensor is designed for the specific size tube, flow rate of the liquid, input and output of the user's specifications and reqirements.
