Smart Oil Gauge

The Smart Oil Gauge provides effortless remote monitoring via smartphone access. Users can check fuel levels from anywhere with internet access, eliminating unnecessary basement trips to view gauges. The system supports alerts and notifications to keep users informed about critical levels.
Key features include: remote monitoring, low-level alerts at ½, 1/3, 1/4, and 1/8 tank capacities, and insights into hourly usage. These capabilities enable informed thermostat adjustments and potential savings on heating costs by understanding daily consumption patterns.
Smart Oil Gauge Duo

The Smart Oil Gauge Duo uses two sensors to reduce blind spots at the top of the tank. This dual-sensor setup helps track deliveries and determine how much oil was delivered even after topping off. The system also provides low-level alerts and remote monitoring similar to the single-gauge model.
With dual sensing, readings stay reliable as levels approach the top of the tank, and users receive timely alerts to prevent outages. The data supports better delivery scheduling and fuel management decisions throughout the heating season.
OEM 7000 Wireless Fuel Level Monitor

The Beckett OEM 7000 Wireless Fuel Level Monitor is a complete kit that includes a receiver, transmitter, and installation accessories. It provides visual and audible warnings when fuel is low, and multiple receivers can be configured to monitor readings from a single transmitter. This setup supports larger homes or multiple zones requiring fuel monitoring.
Designed for ease of integration with existing tanks, it offers a reliable wireless connection and straightforward setup to keep homeowners informed of fuel status and delivery needs without manual gauge checks.
Oil Tank Gauge for 275 & 330 Gallon Vertical

This oil tank gauge is designed for 275 and 330 gallon vertical tanks with depths of 42 to 44 inches. It supports 1.5-inch and 2-inch NPT thread options, expanding compatibility with common residential tanks. The upgraded metal float and precision linkage deliver stable readings, while a high-visibility dial makes it easy to read the oil level at a glance, even in dim basements.
Buying Guide
When choosing an oil monitor for home heating, consider the following factors:
- Measurement approach: Wireless Wi-Fi gauges enable remote checking, while mechanical gauges rely on physical sightlines. For modern convenience, wireless systems with smartphone apps offer more flexibility.
- Sensor technology: Dual-sensor designs reduce top-of-tank blind spots and improve accuracy near full or empty states, while single-sensor models provide straightforward readings.
- Alerts and notifications: Look for customizable low-level alerts (e.g., ½, ⅓, ¼, ⅛) via text or email to prevent outages and optimize deliveries.
- Tank compatibility: Check tank capacity (e.g., 275, 330, 500 gallons) and opening sizes (NPT threads) to ensure the gauge fits your system.
- Delivery tracking: Some monitors can log deliveries and amounts added, which helps reconcile invoices and monitor consumption trends.
- Installation and compatibility: Some systems require professional installation, while others are simple DIY setups compatible with common tank configurations.
- Data insights: Consumption analytics enable thermostat optimization and potential energy savings through better scheduling and temperature management.
- Reliability and support: Consider brands offering reliable customer support, firmware updates, and clear warranty terms.
Across these options, users gain improved visibility into fuel levels, more predictable deliveries, and the ability to manage heating costs with data-driven decisions. The right choice depends on tank size, preferred alerting style, and whether dual-sensor accuracy or multi-zone monitoring is needed for your home.
