The OMEGA® LVAB-10 non-invasive air bubble and level detector provides continuous monitoring of fluid level, air bubbles or foam in chemical processing and infusion systems when connected to a capillary or other type of tube. The LVAB-10 will positively indicate the presence of any break in the flow of any liquid with a TTL output. The unit simply clamps onto the tube, it never comes in contact with the liquid, so there is no chance of contamination. The LVAB-10 consists of an ultrasonic sensor and integral electronics. The electronics sends an ultrasonic signal across the tube, the presence of a bubble, air or foam in the liquid will interrupt the transmission and generate an output. This output is a real-time indication of the disturbance in the liquid.

Temperature Range: 0 to 65°C (32 to 150°F)
Output Signal: TTL (5 Vdc = liquid, 0 Vdc = air bubble)
Response Time: 1 millisecond
Cable Length: 0.9 m (3')
Input Power: 6 to 24 Vdc
Tubing Size: 3/16, 1/4 or 3/8" OD
