WiFi Fluid Level Monitor: Remote Water and Oil Tank Sensor with 4m Range

This wireless fluid level monitor provides a digital solution for tracking the contents of water and oil tanks remotely, removing the uncertainty and inconvenience of manual checks. Designed for integration into modern home automation systems, it uses WiFi connectivity to send real-time data to your smartphone or tablet. You can view current levels and configure custom alerts directly through the dedicated Tuya SmartLife application, which is available for both Android and iOS devices. The sensor’s broad operating temperature range of -20℃ to 70℃ ensures reliable performance in a variety of indoor and protected outdoor environments where tanks are commonly located. With a measuring capability from 0.1 metres up to 4.0 metres and an accuracy of ±0.02 metres, it delivers precise information for better resource management and planning.

Features and Construction

This monitor is built around core functionalities that enable remote, accurate tank management without complex wiring or installation.

Material and Build

The main sensor housing is constructed from PC (Polycarbonate), a material chosen for its durability and ability to protect the internal electronics. This construction provides a robust enclosure suitable for the environments near water and oil storage tanks. The product’s design supports custom OEM, ODM, and OBM configurations, meaning it can be adapted or rebranded for specific professional or integration projects, offering flexibility beyond standard consumer use.

Size and Practical Fit

The key operational specifications centre on its sensing performance rather than physical dimensions. With a measuring range of 0.1 metres to 4.0 metres, it is capable of monitoring tanks with a significant depth, suitable for everything from smaller domestic water tanks to larger storage units. The high accuracy of ±0.02 metres provides trustworthy data, allowing users to make informed decisions about refilling or usage. The device is powered by a standard 100-240VAC to DC 5V adapter, making it compatible with common household and commercial power supplies worldwide.

Uses and Placement

The monitor is specifically intended for liquid storage scenarios, bringing digital convenience to a traditionally manual task.

Event or Professional Use

For settings beyond the typical home, such as agricultural holdings, small workshops, or rental properties with separate water tanks, this device offers a professional monitoring solution. The support for software reengineering and custom configurations (OEM/ODM/OBM) means it can be tailored for specific commercial applications, integrated into broader building management systems, or rebranded for resale. The wide operating temperature tolerance ensures it functions consistently through seasonal changes in unheated outbuildings or garages.

Everyday Home Use

In a residential context, it solves the common problem of not knowing how much water is left in a rainwater harvesting tank, a domestic oil tank for heating, or even a large water storage container. Homeowners can check levels from inside the house via the app, receiving alerts when the tank is getting low, which helps prevent unexpected run-outs. This integrates seamlessly into a smart home ecosystem managed through the Tuya SmartLife platform, allowing for potential automation with other smart devices.

Benefits and Buying Value

The value of this monitor lies in the practical advantages of remote monitoring, accuracy, and system integration.

Reuse and Low Maintenance

As a digital sensor with no moving parts that contact the fluid, it requires minimal ongoing maintenance once installed. The wireless design means it can be easily relocated or repurposed for different tanks if needs change, offering long-term utility. The use of a stable mobile app for control avoids the need for proprietary, disposable hardware controllers, extending the system's usable life through smartphone updates.

Why Choose This Product

This product is a considered choice for anyone seeking to modernise their tank management with a specific, measurable solution. It distinguishes itself through its stated 4.0-metre measuring range and ±0.02m accuracy, providing concrete data rather than simple full/empty indicators. The direct compatibility with the widely-used Tuya SmartLife app offers a user-friendly interface and avoids being locked into a niche, unsupported software platform. The option for custom configuration also presents a clear advantage for installers or businesses looking for a adaptable solution they can tailor to their clients' needs.
