Wireless Level Alarm Systems for Sewage, Septic and Water Tanks

Wireless Level Alarm Receiver
Wireless Level Alarm Transmitter
  The ANG40 wireless level alarm kit is suitable for applications where a remote float switch is required to monitor liquid levels. The system can be configured to monitor a high or low level alarm condition.
The range of the wireless link is 1.6 km* line of sight (3km with larger antenna option).  

The ANG28 transmitter uses a narrow angle float switch to monitor the level of the liquid and will control the Level Alarm in the ANG36 via a wireless link.  

The communication link between the ANG28 and the ANG36 is monitored by a heart beat signal transmitted from the ANG28.  In the event that the heart beat signal is disrupted, the ANG36 will activate the Remote Fault flashing Led. At the same time, the buzzer will emit a beeping signal.

The buzzer can be muted using the switch at the bottom of the ANG36.  

All communication between the ANG28 and the ANG39 is 128-bit AES encrypted which ensures a very high level of system security. This encryption makes it extremely difficult for a 3rd party to interfere with the wireless link.

How to select the right type of float switch


How does the AQUAMETA work ?
AQUAMETA uses a differential pressure sensor,  suspended into the water tank. This pressure sensor measures the depth of water in the water tank. The deeper the water, the higher the pressure reading.
This pressure sensor is connected to the wall mounted AQUAMETA AN5000 Tank Unit. At time of installation the Tank Unit is calibrated using a meter in the Tank Unit so that it knows the maximum water depth to monitor. Using this technique ensures that a reading, accurate to within a couple of mm, can be achieved.  When measuring the level of water in the tank, the Tank Unit takes a pressure reading.  This pressure reading is converted and compared to the maximum depth.  A % reading is calculated and then transmitted to the AQUAMETA display unit which can be located at a remote location. The water level is displayed on a 10 element LED bar graph.
