Smart Ultrasonic Liquid & Water Tank Level Sensor Tuya WiFi - High/Low Alarm

An advanced non-contact liquid level monitoring system engineered for overhead and underground storage tanks, delivering 0.1% measurement accuracy via the global Tuya Smart and Smart Life IoT platforms. It eliminates routine roof climbs, prevents tank overflows, and safeguards lift pumps against destructive dry-running when tanks run empty. Operating via an active ultrasonic echo beam housed in an IP67 weatherproof chassis, it features an integrated 3-meter probe cable with a threaded waterproof female connector. It offers hybrid deployment flexibility through two power options: a UK 3-pin household AC adapter or an autonomous 3.3W solar panel system.

Key Features:

• Real-Time Cloud Tracking: Monitor percentage volume and remaining depth in centimeters from anywhere via 2.4GHz Wi-Fi.
• High-Precision 0.1% Accuracy: Ultrasonic time-of-flight sensor tracks minor level shifts without mechanical contact.
• Multi-Liquid Compatibility: Reliably monitors water, diesel fuel, heating oils, and non-corrosive chemical solutions.
• Smart High/Low Level Alerts: Instant mobile push notifications trigger upon approaching overflow limits or empty thresholds.
• Robust Weatherproof Wiring: 3-meter probe cable equipped with a threaded, silicone-sealed female waterproof connector.
• Hybrid Power Flexibility: Choose between direct household AC power or fully off-grid solar-powered operation.
• Standard G2" (DN50) Thread: 60mm outer diameter threaded mount ensures a rigid, air-tight fit on tank lids.

💡 Technology (Simply Explained):

The sensor utilizes non-invasive Ultrasonic Time-of-Flight (ToF) technology. The acoustic head emits high-frequency sound pulses down toward the liquid surface and captures the reflected return echo. By calculating the microsecond time delta at the speed of sound, the onboard microchip determines the exact distance to the liquid. It compares this against your configured tank depth to calculate real-time volume percentage, avoiding mechanical float jams and chemical scaling.

Supported Measuring Medium:

• Water Systems: Potable drinking water, municipal storage, well water, rainwater catchments, and greywater tanks.
• Fuel & Petroleum: Diesel fuel, industrial lubricants, kerosene, and heating oil tanks.
• Mild Chemical Solutions: Aqueous liquids and chemical blends that do not degrade sealed industrial polypropylene.

Measuring Range & Blind Zone:

• Effective Measurement Range: 10cm to 3.0 meters (0.1m – 3.0m).
• Blind Zone (Dead Band): 0 to 10cm directly below the acoustic transducer face. The sensor must be mounted at least 10cm above the maximum liquid filling line to maintain reliable echo reception.

Tuya Smart & Smart Life Ecosystem Integration:

Connected directly to the Tuya global AI cloud infrastructure—supported by 6 redundant worldwide data centers for secure data synchronization—this device integrates with the Tuya Smart and Smart Life mobile apps:

• Family Device Sharing: Grant immediate viewing and administrative rights to family members or building facility managers.
• Voice Assistant Commands: Check tank level status and receive alert updates via Amazon Alexa and Google Assistant.

App Settings & Advanced Automation Routines:

• Tank Geometry Calibration: Input custom total depth, shape parameters, and volume capacities for precise liter readouts.
• Pump Dry-Run Protection Routine: Automatically shut down a Tuya-connected smart pump relay when tank capacity drops below 15% to prevent motor burnout.
• Auto-Refill & Overflow Prevention: Trigger a smart motorized ball valve to open at 25% capacity and shut off at 95% to stop water waste.
• Consumption Analytics: Review daily and weekly historical level charts to detect plumbing leaks or abnormal usage spikes.

Weatherproofing & Environmental Protection:

The external sensor head and ultrasonic transducer face are sealed to IP67 standards. This construction withstands continuous internal condensation, chlorine fumes, hydrocarbon vapors, direct driving rain, and intense solar UV exposure in demanding climates.

Frequently Asked Questions (FAQs):

Q: Can this ultrasonic sensor monitor diesel fuel and oil tanks?

A: Yes. Because the sensing method is completely non-contact and the outer casing is molded from chemical-resistant polymer, it safely measures diesel fuel, heating oil, and industrial lubricants without liquid degradation.

Q: Why is Tuya/Smart Life integration better than standalone level gauges?

A: True home automation. Beyond simply reading tank percentages on your phone, you can automate external smart relays and water valves to refill tanks and shut off pumps without manual oversight.

Q: Why is a 60mm hole opener drill bit recommended for installation?

A: The G2" (DN50) thread has an outer diameter of approximately 60mm. Using a precise 60mm bit creates an exact circular aperture that allows the rubber sealing ring to lock tight, preventing rain ingress or vapor loss.

Q: Does the solar version run out of power during cloudy weather?

A: No. The 3.3W solar panel recharges the internal 18650 lithium cells during daylight, providing sustained reserve power to keep the Wi-Fi sensor reporting 24/7 through overcast conditions.

Q: How long can the solar battery pack power the sensor during overcast days?

A: Equipped with a 6-cell 18,000mAh reserve, the SP-2417 system powers the Wi-Fi sensor for weeks of total cloud cover. A full recharge cycle takes 16–18 sunlight hours, with real-time capacity monitored directly via four rear LED status lights.

Installation & Wiring:

1. Select a flat, level position on the highest point of the tank lid (away from turbulent inlet fill pipes).
2. Drill a clean 60mm circular opening using the recommended hole opener bit.
3. Insert the G2" threaded neck through the opening and secure the locking nut and rubber gasket firmly underneath.
4. Mate the 3-meter sensor probe cable to the chosen power cable (AC adapter or solar panel lead) and hand-tighten the waterproof threaded collar.
5. Open the Tuya Smart or Smart Life app, tap (+) to add the device, and connect to your local 2.4GHz Wi-Fi network.
6. Enter the total tank height and dead-band offset within device settings to activate live monitoring and custom high/low alarms.

⚠️ Safety Precautions:

1. Avoid placing the sensor directly beneath incoming water streams to prevent false echo reflection from surface turbulence.
2. Maintain at least 10cm of clearance between the sensor face and the maximum liquid fill line to stay clear of the acoustic dead band.
3. Tighten the waterproof cable connector collar firmly to prevent rainwater penetration into the electrical contacts.
