AquaViser Wireless Tank Monitoring System
The AquaViser System is a 12V-powered, wireless tank monitoring and pump control solution designed for caravans, campervans, and mobile or off-grid water systems. It provides real-time visibility of tank levels and water temperature, with the ability to control a water pump remotely — without requiring any signal cabling between components.
System architecture
The system consists of two or three modules:
- AquaViser (LCD Display)
User interface for monitoring and control. Requires only a 12V power connection. - AquaCast Module
Powered by 12V and interfaces with sensors and controls a 12V pump. A second AquaCast module can add another tank to display on the screen (4 total).
All communication is wireless, simplifying installation in existing or pre-fabricated setups.
Key features
- Wireless tank level monitoring and pump control
- No signal wiring required between display and sensing unit (display can be placed anywhere with 12V – even on a different battery).
- 12V installation
- Real-time data transmission between AquaCast and AquaViser
Sensor support
The AquaCast module supports:
- Up to 3 tank level sensors (e.g. drinking, tap or grey water tanks, as well as petrol or diesel tanks)
- Optional water temperature sensor – uses one sensor input (tank 3)
- to show 4 channels (4 tanks, or 3 tanks and 1 temperature) a second AquaCast module is required.
Configuration and control
The system allows:
- Custom tank names and capacities
- 12V water pump control
- Sensor calibration (empty/full voltage thresholds)
- ‘Water low’ as well as ‘waste-water near-full’ custom alarms
- LCD backlight brightness adjustment
- Configurable display dimming timer
- Temperature gauge display (temp probe sold separately)
