An electrical contractor in the Upper Midwest United States provides oilfield tank monitoring for several oil companies. They supply level measurement and control in nearly 400 barrel tanks containing crude oil and/or produced salt water.
The contractor had previously used competitive brands of non-contact radar, guided wave, and buoyancy level measurement devices. They had experienced constant reliability problems requiring multiple site visits to tune out false signals on the level measurement devices. The transmitters were mounted through existing tank openings, and the competitive units needed to be wrapped to insulate the electronics from the cold so they would continue to function.
