Ultrasonic Liquid Level Sensor with Display - Detection up to 8 Meters with App

The Tuya Smart WiFi Water Level Meter with Display is the ideal solution for monitoring tanks, cisterns and basins reliably and professionally , eliminating manual checks, waste and the risk of overflow or lack of water. Thanks to the high-precision ultrasonic sensor , the liquid level is measured in real time with an accuracy of up to 0.01 m , over a detection distance of 40 cm up to 8 meters , making it suitable for both domestic tanks and technical and industrial systems. All data is visible both on the included LCD display , which can be mounted in a convenient position, and directly from your smartphone via the Tuya Smart or Smart Life apps. The 2.4GHz WiFi connection allows remote control from anywhere , while the local display allows immediate consultation even without opening the app. The kit includes a 15-meter RS485 extension cable , ideal for installations where the tank is far from the reading point or the technical room. With customizable alarm thresholds , you can receive automatic notifications when the level is too low or when the tank is full, preventing emergencies and optimizing water management. The system also supports Tuya scenes and automations , allowing you to connect the sensor to smart plugs, relays, or actuators to automatically start pumps, motors, or solenoid valves based on the set level. Also compatible with Amazon Alexa and Google Assistant , the meter integrates seamlessly into your smart ecosystem, offering even simpler and more intuitive control. Installation is quick: simply attach the sensor to the top of the tank, keeping it perpendicular to the liquid, and complete the guided setup via the app. More control, less waste, maximum peace of mind. Choose the Tuya Smart Water Level Meter with Display and transform your tank management into a modern, automatic, and always-on system.

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 wide detection range from 40cm up to 8 meters , making it suitable for deep tanks and cisterns. Additionally, the display is powered via a dedicated power cable (1.5m), 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 system of customizable alarms 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 annual history for complete control. Thanks to long-distance measurement technology, the sensor covers an effective range from 40 cm up to 8 meters , making it ideal for deep 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.

Manage multiple tanks together

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.

Professional Applications: tanks, cisterns and industrial plants

This meter is designed for level control in technical and professional settings, where liquids need to be monitored in tanks and basins of various sizes. It is ideal for water tanks and reservoirs , storage tanks , industrial process tanks , and liquid containers in general. It can also be used on tanks for chemical solutions (such as acids or alkalis ) and on heating/storage systems (e.g., heaters/boilers and storage systems), offering a clear reading and continuous level control via app and display, thus preventing shortages, overfills, and unscheduled shutdowns.

Frequently Asked Questions

1. What exactly does the device measure?

It measures the liquid level in the tank and displays it as a percentage and height/depth, both on the Tuya / Smart Life app and on the LCD display.

2. What is the detection distance?

The maximum detection distance is up to 8 meters. The blind zone is 40 cm (0.4 m), so it cannot measure distances less than 0.4 m.

3. What is “installation height” and why is it important?

This is the distance between the sensor and the bottom of the tank (sensor → tank bottom). It's the main parameter for correctly calibrating the reading in the app/display.

4. Can I set high and low level alarms?

Yes. You can set the Max (full alarm) and Min (low alarm) from the app. You can also manage additional settings directly from the LCD display.

5. Do apps and displays sync with each other?

Yes: When you change a setting on the app or LCD, the other side automatically syncs.

6. How should the sensor be positioned for correct readings?

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.

7. How long does standard shipping take to Italy?

Standard deliveries to Italy generally take 24-48 hours from the time the package leaves the warehouse.

8. When will the order be shipped?

Orders confirmed by 3:30 PM on weekdays (Monday-Friday) are processed and shipped the same day.
