Low Liquid Level Alarm & Monitor
Product Description
This low liquid level monitoring system is available as a low-cost option and can be retro-fitted to almost any plastic or metal tank between 0.5m and 3m in height where you need warnings when the liquid is close to running out e.g. water, process chemicals.
This is a superb, cost-effective way of monitoring and receiving audible warnings of LOW liquid levels without having to repeatedly visit the tank, open its inspection hatch(es) and physically check.
Let the technology do the work for you by using ultrasonic waves to measure liquid height in the tank and wireless technology to show you the liquid levels electronically.
TECHNICAL DATA
Minimum depth: 0.5m / Maximum depth: 3m
- Transmitter = 145 mm tall x 70 mm wide.
- Vertically-mounted on top of tank. Ultrasonic beam points down at liquid and bounces back into receiver to record level.
- Clearance of 130 mm required above tank.
- Receiver = same size and appearance as a standard 3-pin plug (55 mm tall x 50 mm wide). Antenna projects 140 mm above unit.
- Both transmitter and receiver have LCD displays showing level.
- Receiver also includes a red flashing lamp and audible alarm

HOW DOES IT WORK?
- When the equipment (transmitter and receiver) are paired, the transmitter generates a unique RF (radio-frequency) code tying it to the monitor / receiver (which stores in internally and indefinitely). Upon powering up the monitor will associate with the appropriate RF code. This means that equipment can be prepared before shipment to site, particularly relevant for the hire industry.
- A visual scale is displayed on the receiver unit and warning tones sound (from the receiver unit) when the tank is close to empty: typically at the 20% level.
This will be the time to make the call to your service provider for a refill. - In the event of power failure, when the power is restored the two units will find each other but it may take 1-2 hours for correct levels to be recorded. Therefore, it is recommended that the monitor is left on where possible.
- Should equipment become mixed up (e.g. if hire equipment is moved from site to site many times during its lifetime) then it is suggested that transmitter and monitor are paired again to make doubly sure that the local equipment is matched.
- You can avoid the situation where the first time you're aware your tank is empty is when the toilets won't flush!
Those emergency call-outs tend to be most expensive.
WARNING: As with all wireless devices, actual performance may be affected by thick walls / heavy machinery / Faraday cage scenarios between transmitter and receiver.
Features and Benefits
- Remotely monitor your liquid levels and ensure you never run out again with this reliable, accurate and secure gauge
- The transmitter can be fitted easily to most tanks: the receiver can be connected to any standard domestic power socket in your home or site office (within 200 m range - in line of sight, optimum conditions)
- Available with a 3 pin UK / Ireland plug/receiver unit
- The monitor removes the need for a physical, visual check and particularly helps where your tank is difficult to access
