ULS‑03GW Indoor Household WiFi Ultrasonic Liquid Level Monitor: Make Every Drop of Water and Every Liter of Oil “Visible”

Non‑contact ultrasonic measurement + Tuya Smart Life app + real‑time alerts – say goodbye to dry‑run anxiety and overflow waste
To address the five major pain points in household liquid level monitoring, the ULS‑03GW Indoor Household WiFi Ultrasonic Liquid Level Monitor was born. Built around ultrasonic non‑contact measurement technology and deeply integrated into the Tuya Smart Life ecosystem, it provides a “visible and manageable” level management solution for home users.

Core 1: Ultrasonic Non‑Contact Measurement – Never Touch, Never Stick

The ULS‑03GW uses ultrasonic distance measurement. It emits ultrasonic pulses from the top of the container and receives the echo from the liquid surface to accurately calculate the liquid level height. The sensor never touches the liquid, completely eliminating float jamming, probe scaling, and liquid contamination. Moreover, it provides continuous level monitoring rather than a simple on/off switch signal, allowing users to see the complete capacity change from empty to full in real time.

Core 2: Tuya Smart Life App Ecosystem – One App for Everything

The ULS‑03GW seamlessly connects to the Tuya Smart / Smart Life app. Pairing takes only two steps – no complicated setup. Users can view the liquid level percentage and historical data curves on their phone. More importantly, it can be managed together with existing Tuya‑based devices (smart sockets, sensors, air conditioner controllers, etc.) in a single app – no more switching between multiple apps.

Core 3: Smart High/Low Level Alerts – Know When It’s Low, Prevent When It’s Full

Users can set custom high and low level alarm thresholds in the app. When the level drops below the lower limit, a push notification is sent – timely refilling prevents equipment dry‑run damage. When the level exceeds the upper limit, an immediate alarm prevents wasteful overflow. Paired with a smart socket, it can even control a water pump for automatic refilling – pump on when low, off when full – fully unattended.

Core 4: Wide Media Compatibility – Water, Oil, and Liquids

The ULS‑03GW is suitable for a variety of liquid media, including domestic water, cooking oil, fuel oil, diesel, chemical reagents, etc. One device serves multiple household storage needs.

Application Scenarios:

• Rooftop water tank – Remote real‑time viewing, low‑level app alert, automatic reminder to refill.
• Household oil container / fuel tank – Real‑time remaining oil display, plan usage with confidence.
• Water purifier storage tank – Low‑level alarm, avoid dry heating from forgotten refills.
• Aquarium / fish tank – Continuous water level monitoring, timely reminder for topping up or changing water.

Conclusion:

From manual dipsticks to stuck floats, from probe scaling to fragmented apps – the many pain points of household liquid level management finally have a one‑stop solution. The ULS‑03GW, grounded in ultrasonic technology and bridged by the Tuya Smart ecosystem, makes every drop of water and every liter of oil “visible and manageable”.

Step into the era of smart liquid level monitoring – ULS‑03GW, turn your water tank from a household blind spot into a fully visible asset.
