This wireless, low liquid level monitoring system is available as a low-cost option and can be fitted to Above or Below Ground tanks, indeed, fitted to almost any plastic or metal tank between 0.5m and 3m in height. It is most often used to safely monitor low liquid levels in tanks positioned at height or positioned in inaccessible places e.g. underground.
This unit is effectively the same as our standard Apollo low level alarm except that the sensor and transmitter are separated into two distinct parts (see gallery and/or product sheet, below). The sensor is mounted in a robust 4cm diameter x 3cms plastic housing, which is fixed to the tank and which in turn connects by a 10m cable to the battery-powered transmitter.
The sensor is mounted on the tank (i.e. below ground, at height or in a hard to reach place) and emits ultrasonic waves to measure liquid height in the tank. This liquid height is transferred via the 10m cable to the transmitter, which is mounted in a safe, accessible place and which uses wireless technology to send tank levels to the plug in receiver unit for the user to view at their convenience.
The receiver plug unit is generally plugged in to a 230v power socket within 200m of the transmitter and gives audible and visual warnings of tank levels from about 80% full. The Apollo XT Low level unit makes the monitoring of inaccessible tanks simpler and safer, achieving Health & Safety requirements whilst also avoiding unnecessary call outs for refills.
WARNING: As with all wireless devices, actual performance may be affected by thick walls / heavy machinery / Faraday cage scenarios between transmitter and receiver.
