Floating sensor

As part of its portfolio, Vega offers a level switch system capable of detecting the difference between rainwater and hydrocarbons in a bunded area around storage tanks.

This means there is no danger of hydrocarbons being pumped into the drainage/effluent system should the tank develop a leak.

The floating sensor arrangement always remains on the liquid surface, using two detection technologies.

One vibrating sensor can detect and notify any liquid, while a second conductivity sensor confirms whether it is hydrocarbon or water present.

The system works on a voting basis, so both have to signal that liquid is present to confirm rainwater.

If only the vibrating switch detects a liquid, it is a hydrocarbon. This can then trigger an alarm to stop any automated pumping process and initiate an intervention.
