Key benefits — why you need this ultrasonic tank level meter Monitor tank water level and temperature from inside your home: transmitter mounts on top of the tank and sends level and temperature data to the indoor receiver up to 100 metres away. Prevent supply interruptions and equipment damage: set high/low level alarms and an empty-tank alert so you are notified before problems occur. Fast, easy-to-read status at a glance: 3.3 inch LCD with a 10-segment bar chart and clear numeric readouts for quick decisions. What it does (functions and performance) Accurate ultrasonic level measurement: the rooftop transmitter uses an ultrasonic sensor to continuously measure liquid depth in the tank. Temperature monitoring: a thermal sensor on the transmitter reports tank temperature; the indoor receiver also displays indoor temperature. Transmission range: reliable wireless communication from transmitter to receiver up to 100 metres. Display and recording: 3.3 inch LCD shows tank level as a 10-element bar chart, tank temperature, and indoor temperature. Records and displays minimum and maximum tank levels. Temperature ranges and accuracy: indoor temperature range 0 to 60°C; outdoor (tank) temperature range -40 to 60°C; temperature accuracy ±1°C. Time and units: displays time in 12/24-hour format and supports both °C and °F. Key features that make it stand out Remote, non-contact measurement — ultrasonic sensor avoids floats or probes inside the tank that can foul or fail. Clear visual level indicator — 10-element bar chart provides an immediate sense of remaining volume without interpreting complex data. Alerts and history — high/low and empty-tank alarms plus min/max level recording help you manage refills and maintenance proactively. Flexible placement — indoor receiver can be wall mounted or positioned on a tabletop using an extendable stand to fit your home or office layout. Installation and compatibility Transmitter mounts at the top of the water tank and transmits data wirelessly to the receiver up to 100 metres away. Receiver offers two placement options: wall mounting or free-standing on a worktop, table, or desk using the extendable stand. Display options: choose °C or °F and 12/24-hour time format to match your preference. Practical use scenarios 1) Residential rainwater storage: monitor backyard or rooftop cistern water levels and tank temperature from the house to avoid running out of water for gardening or household use. 2) Remote livestock or irrigation tanks: place the transmitter on an outdoor tank and receive level and temperature updates inside your home or farm office to plan refills and prevent pump dry-run. 3) Seasonal freeze protection: track tank temperature and receive alerts when levels are low so you can take action during freezing weather or when supply lines are vulnerable.
