Shuttle Water Level Sensor

Applications

Multiple sensors with measuring ranges from 10 cm to 25 m.
Learns how the tank is arranged with piping, pumps and other items interfering with the measurement.
Ignores turbulence and electrical interference (even a slow moving mixer can pass through without influencing the measurement).
Two output relays for level/system alarm or alternating pump control with duty and standby cycles.
4-20 mA output with zero and span adjustment.
Indicates strength of echo signal with a bar graph.
Narrow ultrasonic pulse signal concentrates signal strength for minimum sensitivity to foam/sludge on the liquid surface.
Easy to read LCD-display for both setup and indication.
Actual level indicated with bar graph and digits in millimeters, centimeters, meters, feet and inches.
Readout can be chosen as relative or absolute level.
10-30 V DC or 230 V AC supply.
FM approved sensors for hazardous areas.
