TECHNOLOGY
Introtek air bubble detectors and liquid level sensors
utilize high-frequency acoustic energy to monitor tubing
or vessels for the presence of air, air bubbles, foam or
liquid. The sensor’s piezoelectric crystals are placed in
direct contact with the desired point of detection. Air
detection sensors and electronics emit pulses of ultrasonic energy which are sent through tubing and
returned within a specified “window” of time. If air is
present, the ultrasonic signal does not arrive within
this “window” of time and a warning or dry signal is
immediately transmitted.
