Abstract
An apparatus for measuring a level of a fluid and detecting water in a storage container is provided. The apparatus comprises a signal-based fluid level measurement apparatus and a water detection device. The signal-based fluid level measurement apparatus has a first multistatic probe conveying a first signal and a second multistatic probe conveying a second signal. The first and second multistatic probes are electrically coupled by a float-coupler. The signal-based fluid level measurement apparatus determines the level of the fluid in the storage container based at least in part on a time delay between the first and second signals. The water detection device is operably coupled to the fluid level measurement apparatus. The water detection device monitors at least one of conduction and a dielectric constant between exposed ends of the first and second multistatic probes. As such, a presence of the water in the storage tank is detected.
