Ultimate Controller


Ultimate Controller

An integrated approach

Ultimate Controller

Ultimate Controller is a control system that combines ultrasonic level and flow measurement, RTU and advanced pump control in one economic, easily programmed, modular unit with dedicated web server remote control and touchscreen HMI - now with WITS Protocol.

Integrating the world's leading non-contacting ultrasonic advanced controller with patented functions that reduce energy costs, aid Asset Management, reduce installation and maintenance costs and improve Compliance.

Ultimate Controller is modular and expandable, with peripherals offering unlimited I/O, pump power monitoring and even a remote infra-red camera, allowing remote viewing of the well and the process.

One supplier, one number to ring for the complete control package


Ultimate Features - End to End Cost Savings

  • Operational Cost Saving by high energy cost avoidance, pre-blockage detection, automatic resets and the selection of the most efficient pump
