The Rain Alert features a TRANSMITTER that fits to the top of the tank and a RECEIVER which is plugged into a powerpoint at a convenient location.
The Rain Alert uses ultrasonic radio wave technology to measure the level of fluid in the tank. It then uses wireless transmission to send the measured level to the Receiver.
The Transmitter is fitted to the top of the tank (see Diagram 1) and uses 'ultrasonics' to measure the level of fluid in the tank/s.
It then transmits a reading to the Receiver (see Diagram 2) which is plugged into a powerpoint, located in a convenient place.
The level is continuously displayed on the small Liquid Crystal Display (LCD) panel of the Receiver (see Diagram 3).
EARLY WARNING. When the tank level gets below a pre-determined level, a Tank Fill picture flashes on the panel. This early warning means you can give plenty of notice if you need to order in supplies for your tank.
EMPTY. If the tank level decreases further then a red warning light turns on and begins to flash indicating the tank is almost empty. Note: If you have town water in your area, and your rainwater tank is fitted with a 'top-up' device or mains water 'switching' device, the red warning light indicates that it is likely that mains water is already being used.
