How does Rain Alert work ?
Rain Alert is installed on top of the water tank and uses a
ultrasonic sound beam to sense how far the water surface is from it.
The vertical height from the sensor on top of the tank to the bottom
of the water tank is set on the Rain Alert display unit at time of
installation. This is accomplished by setting switches on the back
of the display unit. The depth of the water tank can be set in
increments of 50mm.
Once every hour, the Rain Alert transmitter senses the level of the
water in the tank by sending out a beam of ultrasonic sound. The
sound is reflected from the water surface and is detected by the
Rain Alert transmitter. The transmitter measures the time it takes
for the sound to travel to the water surface and back again. The
lower the water level, the longer it takes the sound to travel.
This measurement is then transmitted to the Rain Alert Display unit
which can be located up to 200m away (
line of sight). The Display Unit then
displays the water tank level on a 10 element LCD bar graph.
