Step One - Tank Level Measurement

For accurate level monitoring, the battery operated TankScan^® monitor is situated on top of the tank and a thin wave guide (probe) is immersed in the fluid. In operation, a very short, very low energy electromagnetic impulse is generated through MIR (Mircopower Impulse Radar) technology from the top mounted sensor down the thin probe that is immersed in the liquid/fluid. The sudden change in the dielectic at the fluid surface causes some of the impulse energy to be reflected back up the probe towards the MIR Monitor.

As different substances have different modulation effects on the impulse signal – air has little effect while liquids have a relatively large effect - the TankScan monitor can accurately sense the time delay between the impulse generated and the modulated reflection. The time difference between pulse reflections and the maximum calibrated time delay is proportional to the level of the liquid. The wave guide is Teflon coated stainless steel ensuring accurate measurements (+/- 0.3” or 0.5% of probe length) in non-corrosive liquids such as fuels and oils. The monitor then sends a wireless signal to the fluid level controller with the relevant information.

The TankScan Monitor is capable of performing tank level measurements on tanks up to 20 feet high and no limitations on volume or width. With an intrinsically safe design, the TankScan monitor is a safe and effective product for tank level monitoring.
