  • Page 10: About The Ultra 4

    The Ultra 4 does not offer a multiple range of functions blended together which leads to complicated calibration and a compromise to the specification. The Ultra 4 is the first ever system to offer the ability to dedicate the functionality of the unit to any of three specific duties i.e., level or volume measurement, pump control, or flow measurement.

  • Page 11: Functional Description

    Ultra 4 can measure from zero to 40m from the face of the transducer to the surface being monitored, dependent on the application chosen and transducer used.
