Uehling Instrument Company - Ultrasonic Digital Tank-O-Meter

Microprocessor Based Continuous Liquid Level Measurement Systems

Non-Contact Measurement for Tanks, Wells, Sumps, Lakes

Relay Outputs for High/Low Alarms Pump/Valve Control

How does is work? The sensor produces ultrasonic pulses. The liquid reflects the pulses. Reflected pulses are sampled and processed to determine the current level and simultaneously compensated for temperature fluctuation. A signal is subsequently sent to the digital display where it is converted and displayed in any single or dual engineering unit. (i.e. inches/Gallons; mm/Liters, etc.) Non-linear calibration for virtually any shape thank is optional.
