- Easier Well Monitoring System


Levelese Continuous Water Well Level Sensor, the simple, price, value and accuracy leader for well water level sensing and display, is an ideal soltution for aquifer level recording and underground pollution plume tracking.

Specified, patented and designed by engineers with half a century’s individual experience in level instrumentation, Levelese has been designed to operate in the most stringent environments ranging from marine oil storage, acidic material transportation vessels to pure well water. Levelese© is not affected by turbulence and the actual depth of the well.

Levelese continuous level monitors are:

  • Easy to install and maintain
  • Highly reliable
  • Without moving parts
  • Possess wide rageablitly from 0.5 ft to more than 100 ft
  • Demonstrate negligible sensing errors
  • Excellent with foam or turbulent applications
  • Independent of specific gravity

Using the principle of buoyancy the Levelese level measuring system weighs an inert chain, secured below the fluid surface and determines the inverse of liquid level and converts it to an analog or digital electronic signal for indication, alarming or continuous or on-demand transmission
