 ULTRASONIC LEVEL SENSORS

General

Shuttle® is an advanced microprocessor based ultrasonic level meter with a newly developed intelligent, precise measuring system utilizing the latest hardware and
software technology.

Shuttle® provides simple and logical operation, using advanced technology resulting in a high quality product at a competitive price.

Shuttle® is designed to measure water levels as well as other fluids and aggressive media, where the ultrasonic sensor is
not in contact with the media.

 

     Characteristics

  • Ultrasonic measuring system with measuring ranges from 10 cm to 15 metres.

  • Learning-function allows the Shuttle® Level Transmitter to learn how the tank is arranged with piping, pumps and other items that might disturb the measurement. The system also ignores turbulence and electrical interference, so even a slow moving mixer can pass through the ultrasonic beam without any influence on the measurement.

  • 2 output relays for level / system alarm or pump control with duty and standby cycles.

  • 4 - 20 mA output with zero and span adjustment.

  • Indication of the strength of the echo signal with a bargraph.

  • Very narrow ultrasonic pulse signal gives great signal strength and minimum sensitivity to foam and sludge on the surface of the liquid.

  • Easy to read LCD-display for both setup and indication. Actual level is indicated with both a bargraph and with digits in millimetres, centimetres, metres, feet and inches. The digital readout can be chosen as either relative level or absolute level.

  • 10 - 30 V DC or 230 / 115 V AC supply.

  • Intrinsically safe ultrasonic sensor (CENELEC Zone 2).
       Operation
 
Shuttle® needs no operation after initial setup. 9 function buttons behind the front panel are used to configure:
  • Unit selection in either metres, centimetres, millimetres, feet and inches.
  • Adjustment of zero level of the measurement and selection of relative or absolute reference.
  • Zero and span for the mA output.
  • Function for the two 2 output relays - off, level alarm, system alarm or pump control with alternation.
  • Learning function, so the level meter recognizes how the wetwell is arranged with pumps, piping and other disturbing elements. The measurement will not be affected by false echos.
       Application
 
Shuttle® is well suited for any ultrasonic level measurement. The level transmitter may also be used for measuring and control of levels in tanks with contaminated and/or aggressive media.

Typical applications is measurement and control in:

  • stormflow tanks
  • pump stations
  • tanks in sewage treatment plants
  • tanks in water plants
  • tanks and vessels in process- and
    provisions industries
