Wireless Water and Fuel Level Sensor Alarm Indicator for remote tank monitoring with 4.0m measuring range and ±0.02m accuracy using 2.4GHz WiFi connectivity compatible with Tuya SmartLife app via Android or iOS mobile devices
Wireless Fluid Level Monitor with 4.0 Metre Range and Smartphone App Control for Remote Tank Management

This wireless water and fuel level sensor provides a practical solution for remote monitoring of liquid storage containers in home automation systems. Manufactured in Shaanxi, China, by brand Moray under model ME201W, the device eliminates the need for physical tank checks by delivering real-time level data directly to your smartphone. Using 2.4GHz WiFi connectivity and compatible with both Android and iOS operating systems through the Tuya SmartLife app, this sensor offers convenience and accessibility for homeowners managing water tanks, oil reserves, or other liquid storage systems where regular monitoring is essential but manual checking is inconvenient or impractical.
Features and Construction

The Moray ME201W wireless level monitor combines measurement precision with practical remote access capabilities, designed specifically for residential tank management applications.
Material and Build
Constructed from PC (polycarbonate) material, this sensor housing provides durability while maintaining signal transparency for wireless communication. The PC construction ensures structural integrity across the specified operating temperature range from -20℃ to 70℃, making it suitable for both indoor installations and outdoor applications where temperature fluctuations occur. The housing protects the internal components while allowing for accurate fluid level detection through its sensor technology.
Size and Practical Fit
While specific physical dimensions aren't provided in the source data, the device is designed for tank installation with a measuring range extending from 0.1 metres to 4.0 metres of liquid depth. This range accommodates most residential water storage tanks and fuel containers. The ±0.02 metre accuracy specification ensures reliable monitoring that can help prevent overflow situations or alert you to low levels before they become problematic. Installation requires positioning within the tank to utilise this full measurement capability effectively.
Uses and Placement

This wireless sensor serves multiple monitoring applications where remote access to tank level information adds convenience and prevents potential issues.
Event or Professional Use
For professional applications or event setups requiring temporary liquid storage, this wireless monitor allows organisers to track water or fuel levels without physical inspection. The 2.4GHz WiFi connectivity means level data can be accessed from any location with internet access, useful for large properties, agricultural settings, or temporary installations. The operating temperature range supports use in various environments, while the Tuya SmartLife app compatibility provides straightforward monitoring without specialised software.
Everyday Home Use
In residential settings, this sensor offers practical monitoring for rainwater collection tanks, heating oil reserves, or emergency water storage. Homeowners can check levels remotely while away from the property or receive alerts when levels reach predetermined thresholds. The Android and iOS compatibility ensures most smartphone users can access the monitoring functions without additional equipment. The device's application specifically targets water and oil tanks, though installation specifics for different liquid types should be confirmed.
Benefits and Buying Value

This wireless monitoring solution provides specific advantages for users seeking to automate tank management without complex installation or ongoing maintenance requirements.
Reuse and Low Maintenance
The PC construction and specified operating parameters suggest a design intended for continued use rather than single applications. The wireless nature eliminates wiring maintenance concerns, while the power supply flexibility (100-240VAC to DC 5V) supports installation in various locations with standard power access. The manufacturer's support for software reengineering indicates potential for future updates or customisation, though specific upgrade paths would require direct consultation.
Why Choose This Product
This wireless fluid level monitor distinguishes itself through its combination of measurement precision (±0.02m accuracy), practical remote access via smartphone, and compatibility with common home automation platforms through the Tuya SmartLife ecosystem. The 4.0 metre measuring range addresses most residential tank requirements, while the temperature tolerance ensures reliable operation in varied conditions. The manufacturer's support for custom OEM, ODM, and OBM services provides additional flexibility for specific application requirements beyond standard configurations.
