Washdown Alarms

The Aquasentry washdown tank alarm is used to monitor silt and liquid levels in underwater washdown areas.

The unit allows the user to set a high level probe at a pre-determined level to ensure that the washdown area does not overflow in the event of a heavy rainfall or usage.

With the GSM capability, in the event of a high level event, the site is protected 24/7 and reduces the risk of a pollution incident, whilst reducing waste management costs.

General operation

An alarm system with up to 3 probe sensors is installed within the washdown tank to automatically detect the water and silt levels of within.

If excessive levels are reached, the alarm activates a klaxon or beacon (sold separately) to provide an audible or visual notification of excessive liquid levels, as well as sending a text message to up to 16 designated numbers.
