Connected Consumer Fuel Smart Oil Gauge Duo – Dual‑Sensor Wi‑Fi Heating Oil Tank Gauge for 138–550 gal Tanks, Alexa‑Compatible, Ac

The Smart Oil Gauge Duo is a dual‑sensor Wi‑Fi monitor that gives real‑time, remote readings and alerts for residential and commercial heating oil tanks.

Designed by Connected Consumer Fuel, this advanced oil tank gauge replaces guesswork with precise level monitoring using two independent sensors that remove the top‑of‑tank blind spot. It connects to your home network to stream level data, send low‑fuel notifications, and provide hourly and daily usage insights. The Duo fits common steel tank sizes — including 138, 220, 275, 330, 500 and 550 gallon tanks — and works with vertical or horizontal installations, single tanks, or side‑by‑side arrays.

How does the dual‑sensor design improve accuracy?

The Duo uses two ultrasonic sensors positioned to cover the full height of the tank, eliminating the dead zone near the fill cap that single sensors can miss. That means accurate readings even after partial or full deliveries and fewer false full or low alerts. The combined sensor data reduces noise from surface turbulence and improves repeatability of measurements.

• Two ultrasonic sensors remove the blind spot at the top of the tank
• More reliable delivery detection and post‑fill readings
• Reduced false alarms from sloshing or foam

What notifications and insights will I receive on my phone?

Once connected to Wi‑Fi, the Smart Oil Gauge Duo sends push, text, and email alerts at user‑defined thresholds like 1/2, 1/3, 1/4, and 1/8 tank levels. The app also displays consumption trends by hour and day so you can spot unusual usage or plan deliveries. Historical reports help you optimize thermostat settings or troubleshoot leaks and sudden drops.

• Email, text, and push alerts at preset fill levels
• Hourly and daily consumption graphs for pattern analysis
• Delivery tracking to verify amounts added after a refill

Which tanks and installations are supported?

The device is built to fit standard steel tanks: 138, 220, 240, 275, 330 (vertical or horizontal) and 500/550 gallon cylindrical tanks. It uses a 2" NPT mounting interface and works alongside common float gauges and vial assemblies. Adapters are available for Roth 400L/620L/1000L types and tanks with 1.25" or 1.5" openings.

• Compatible with a wide range of steel tank sizes and orientations
• 2" NPT mount fits new steel tanks and many retrofit scenarios
• Adapters available for Roth and non‑standard openings

Can it integrate with smart home assistants and other systems?

Yes — the Smart Oil Gauge Duo supports popular voice assistants such as Alexa, allowing simple voice checks and routine queries. The Wi‑Fi connection also enables cloud access for third‑party integration and remote monitoring from anywhere with internet access. Setup is app‑guided and includes steps for secure network connection and device registration.

• Works with Alexa for voice‑driven tank checks
• Cloud access for remote monitoring and data export
• App‑guided Wi‑Fi setup and secure device pairing

Who is this for? Homeowners, property managers, and small‑business owners who rely on heating oil and want to eliminate manual checks, surprise runouts, and inefficient deliveries will benefit most from the Smart Oil Gauge Duo. It’s especially useful for multi‑tank setups, remote cottages, landlords managing several properties, and anyone who values automated alerts, accurate delivery verification, and clear consumption analytics without intrusive installation work.
