Transform Cisterns and Tanks into Smart: Detection up to 2.9 meters, alarms and automations
The Tuya Smart WiFi Liquid Level Meter with Display transforms the management of tanks and reservoirs into a modern, precise and automated system. Thanks to contactless ultrasonic measurement , the sensor works from above without touching the liquid: less scaling, less maintenance and greater reliability over time. In just a few seconds you can view the level in real time directly on your smartphone via the Tuya Smart / Smart Life app and on the LCD display , so you always have an immediate reading both locally and remotely. The biggest advantage? No more “eye checks” or surprises: from the app you can see the percentage , level and trend of variations, and you can set high and low level alarms to receive notifications when the tank is almost empty or close to full. This way you avoid waste, overflows and system downtime, improving the safety and efficiency of liquid management. Plus, since it's compatible with the Tuya ecosystem, you can create intelligent scenes and automations : for example, connect it to a smart socket or a relay to start or stop pumps, motors or solenoid valves based on the set level. It's the ideal solution for those seeking professional yet easy-to-use monitoring of water tanks, technical tanks, and systems where continuous monitoring really makes a difference. Choose it and make your tank "smart": more control, more safety, fewer problems.
Check the water level anytime, anywhere
The meter connects directly to the Tuya Smart / Smart Life apps via 2.4GHz Wi-Fi , allowing you to check the tank level anytime from your smartphone. The interface clearly displays the fill percentage , level in meters, and trend of changes, so you can monitor consumption and refills without being physically near the tank. The reading is accurate to 0.01 m , so even the remaining level is clearly visible: a concrete advantage for preventing sudden shortages or overfills and managing the system more safely and efficiently. Furthermore, integration with Amazon Alexa and Google Assistant allows the device to be included in the smart ecosystem, using it within scenes and voice automations for even simpler and more centralized management of the system. An ideal solution for those who want remote control, precision, and home automation integration in applications on tanks and technical systems.
Complete Kit with Display + 15m RS485 Extension Cable
This kit is designed for real-world installations where the sensor and reading point are not close together: it includes an LCD display and a 15-meter RS485 extension cable to conveniently connect the meter to the display even in utility rooms, control panels, tank rooms, or multi-level systems. The sensor reads the level from above with a detection range from 10 cmto 2.9 meters , making it suitable for tanks and cisterns. Additionally, the display is powered via a dedicated power cable (1.5 m), so you have a control station always ready, in addition to app monitoring.
Customizable Level Alarms: Instant alerts
The Tuya water level meter integrates an advanced customizable alarm system that allows you to monitor the tank continuously and automatically, without manual checks. From the Tuya Smart or Smart Life app, you can freely set the intervention thresholds based on the actual height of the liquid or the percentage of filling , choosing when to receive the maximum level (Full Alarm) or minimum level (Low Alarm) alert. When the water level exceeds or falls below the set values, you will receive immediate push notifications on your smartphone , allowing you to intervene promptly to avoid overflows, dry running of pumps, service interruptions or waste . The system clearly displays the status of the tank (Normal, Full, Low), the depth of the liquid in meters and the remaining percentage, with daily, monthly and yearly history for complete control. Thanks to long-distance measurement technology, the sensor covers an effective range from 10 cm up to 2.9 meters , making it ideal for tanks and technical installations. Smart alarm management makes this device a reliable solution for those who want security, prevention and automatic control , even remotely, integrable into the Tuya home automation ecosystem and usable in advanced professional and residential scenarios.
Intuitive Display: Real-time level
The integrated LCD display makes it easy to monitor the tank even without opening the app. At a glance, you can see the real-time water level with clear graphics and percentages, so you know how much water is available. In addition to the level, the display also shows the room temperature and time , helping you keep track of the system's key parameters. Thanks to the controls and free settings , you can easily manage the main functions directly from the panel, providing continuous and practical monitoring in any technical context where a quick and reliable reading is required.
Smart Automations and Tuya Scenes
With Tuya Automations, you can go beyond simply reading the level: the sensor becomes a real “control” for your system. In the Tuya Smart / Smart Life app, you can create intelligent scenes based on conditions such as fill percentage , level in meters , or status (Normal / Full Alarm / Low Alarm) . In practice, when the level reaches a threshold you decide, the app can automatically perform an action. Concrete example: you can connect a Tuya smart plug (or a compatible relay/actuator) to the pump or a motor and set scenes such as “ if low level → turn pump on ” or “ if high level → turn pump off ”, avoiding waste, overflows, and dry running. Similarly, you can start/stop solenoid valves, filling systems, or light/sound alerts connected to Tuya devices. The result is more automatic, safer, and more professional control, with notifications and centralized management directly from your smartphone.
Do you have multiple tanks to monitor? With the Group Control feature, you can manage multiple level gauges within the same Tuya Smart / Smart Life app, keeping everything organized on a single screen. You can assign a name to each tank (e.g. , Tank A, Tank B, Tank C ) and quickly check the percentage, level, and status of each, without confusion or switching between devices. This is a very useful feature in systems with multiple tanks or cisterns (storage, process, reserve, separate tanks), because it allows you to have an immediate overview and intervene immediately when a tank drops below the threshold or approaches full. Furthermore, by combining it with alarms and automations , you can create even more efficient management: each tank has its own thresholds and notifications, but control remains centralized and simple.
Easy 3-step installation
Installation is quick and designed for real-world systems: Step 1 – Drill the hole in the lid/top of the tank in the correct position. Step 2 – Insert and secure the sensor. Step 3 – Connect the system to the display (with an RS485 extension cable if needed) and the Tuya Smart/Smart Life app to start monitoring immediately. To obtain reliable measurements, it's important to follow a few rules: the sensor must be mounted perpendicular to the liquid surface, as tilts can cause incorrect readings. Avoid placing it too close to internal walls and away from water inlets/outlets or turbulence, this will reduce "false echoes" and achieve a more stable and accurate level. In practice: central mounting, facing downwards, and away from obstacles = better performance.
Areas of use: suitable for tanks, reservoirs and technical systems
This meter is designed for real-world applications on tanks and reservoirs where reliable liquid level control is required. It is ideal for water tanks (storage, distribution, reserve), plant tanks and basins , industrial process tanks , and liquid tanks in general. It can also be used on tanks for chemical solutions (e.g., acids/alkalis ) and on systems connected to heaters/boilers and storage systems, offering continuous monitoring to prevent shortages, overfills, and system downtime . In short, it's the right choice when you need to know "how much liquid is there" in a clear, controllable, and constantly updated way.
The meter is suitable for monitoring the level of liquids in tanks and cisterns, such as water, technical liquids, and non-foaming solutions. It is suitable for domestic, industrial, and process tanks.
Detection occurs via an ultrasonic sensor installed in the upper part of the tank. The sensor does not come into contact with the liquid, reducing wear and maintenance.
It should be mounted perpendicular to the liquid surface (straight down). Avoid installation near walls, inlets/outlets, or areas with turbulence to reduce false echoes and unstable readings.
