Level-Pro Tank Gauging System

The LEVEL-PRO Tank Gauging System was designed to offer the oil and gas industry a rugged, reliable and economical solution for the monitoring and management of stationary, mobile and, pressurized tanks and vessels. The durable and dependable design of the LEVEL-PRO entrusts proven positive contact with the fluid for accuracy and reliability.  Patented measurement technology closely monitors movement of the float to produce highly accurate readings. The Level-Pro system can be installed in virtually any tank. Various mounting methods can be utilized to exit the tank or vessel and systems can be installed while the tank is in service without the need for modification.  The system is available as a wired, wireless or mesh network solution for application flexibility. 


  • The wired controller coupled with the Multi-Tank Display can accept up to 20 gauges.
  • The wireless controller coupled with the wireless SMART display can support up to 4 gauges in the most remote of locations.
  • The wireless controller when coupled with the Wireless Tank Card (WTC) establishes a mesh network and provides a Modbus/Slave communications port for direct use by a PLC/SCADA system to wirelessly access tank data. The WTC supports up to 20 gauges.



  • Totally sealed gauge
  • High-Level Alarm/Shutdown
  • Easy, innovative installation
  • Connects to any control system
  • Optional satellite communication on all models via QMI
  • Emulsion measurement. Varying SG has no effect on function
  • Oilfield tested; Oilfield approved – compatible with wide array of oil field fluids
