Model UC-4000

World’s First Multi-Tank Ultrasonic Level Sensor

Smart Enough to Monitor up to 9 Tanks of Any Size Without Calibration.

Our Motto: Just install UC-4000 and turn power on. It will be working for you! It’s that simple to use.

  • Automatically scans all tanks.
  • Automatically displays level, volume or opt. weight of each tank in sequence.
  • No calibration, no programming.
  • Non-contact monitoring.
  • Easy installation – only one box. All transducer cables can be placed in a common conduit.
  • No maintenance.
  • Use for any liquids, slurries or suitable solids.
  • U.S. made.
UC-4000 Level Sensor can sense up to 9 tanks.
Call 941-964-1361 with any question.


  • Scans automatically up to 9 tanks of any size. Monitoring is non-contact with transducers mounted in the tanks above the highest level of fill.
  • Displays automatically level or volume in each tank in sequence.
  • Provides outputs for each tank, up to 3 set points and a 4 to 20 mA current.
  • Transmits level or volume for each tank via RS232C computer connectible output, up to 2000 feet distance.


  • Only one control box to install, only one power connection. The enclosure nominal size is 13 x 11 x 6 inches.
  • All transducer cables can be placed in a common conduit. This represents a substantial cost saving.
  • Very cost effective when compared with single units.
  • Easy system expansion due to modular construction.
  • UC-4000 is simple to use, representing the most modern technology available anywhere.
Tanl level monitor.


During regular operation, the controller automatically and continuously monitors all tanks. The level or volume (as selected) in each tank is displayed in sequence for approximately two seconds, starting with tank 1, then 2 and so on until the last monitored tank. The cycle continuously repeats. Large, alphanumeric LCD display shows level in inches, feet and meters or displays volume in US gallons, liters or other units for vertical as well as horizontal tanks. No strapping tables or programming required.

Scan of all nine tanks is completed approximately every second, independent of display. During each second all measurements, set points and current outputs have been updated. The outputs, including the 4-20 mA current, are independent and appear as if each were coming from an individual single unit.
