Stationary Tank Monitors

What is a stationary tank monitor?

A stationary tank monitor is a single device that measures the level in a fixed storage tank and reports it remotely, with the sensor and gateway built to work together out of the box.

Traditional remote monitoring means buying a sensor, buying a gateway, wiring them together, and configuring both. A stationary tank monitor removes those steps. It is built for one job: keeping an eye on a tank that stays in one place, such as a farm propane tank, a generator fuel tank, a chemical day tank, or a remote water tank.

Because the level data reaches a cloud dashboard instead of a clipboard, you can see every tank from your desk or phone, plan deliveries from actual levels, and stop sending people out just to read a gauge. For a broader look at the technology, sensor types, and cost drivers, see our guide to tank level monitoring.

How does a stationary tank monitor work?

A stationary tank monitor reads the tank level with its sensor, sends the reading over a cellular or satellite network, and the LevelCon platform turns it into dashboards, trends, and alerts.

Readings arrive on a schedule rather than as a nonstop stream, which keeps power and data use low while still giving you near-live visibility of every tank.

• Measure. The level sensor reads the tank at scheduled intervals. Sensor options are selected per liquid type.
• Send. The built-in gateway transmits each reading over cellular or satellite, so the tank reports without a local network.
• See. Readings appear in the LevelCon web dashboard and mobile app, with each tank on a live map and its level history plotted over time.
• Act. Alerts go out when a level crosses a threshold you set, and level trends support automatic reorder points for fuel and propane delivery routes.

Which tanks can a stationary tank monitor watch?

LevelCon stationary tank monitors are used on fuel, propane, chemical, and water storage tanks of varying sizes and materials.

If you are not sure which sensor fits your product, our comparison of radar vs ultrasonic by application is a good starting point, or a LevelCon engineer can recommend one.

• Fuel tanks for generators, fleet yards, and equipment, where trend data supports delivery scheduling.
• Propane tanks on farms and commercial sites, where a run-out can halt heating or drying. See propane tank monitoring.
• Chemical tanks, where the sensor is chosen to suit the product being stored.
• Water tanks for livestock, irrigation, and remote facilities.

How is a stationary tank monitor installed?

The sensor and gateway ship pre-integrated and pre-configured, so installation comes down to a single mounting step.

There is no separate gateway to mount, no cable to run between a sensor and a gateway, and no field configuration to work through before the tank starts reporting. For sites where running power or wiring to the tank isn't practical, the Wireless STM removes that requirement.

Once mounted, the tank appears in the LevelCon platform alongside any other LevelCon gateways and sensors you already run, so a stationary monitor never becomes a separate system to manage.

What alerts does a stationary tank monitor send?

It sends low-level, high-level, and rate-of-change alerts by SMS, email, or the LevelCon mobile app.

Thresholds are configurable per tank, and alerts can be routed to the people responsible for that tank. The platform also offers a REST API and Modbus connectivity if you want tank data in SCADA, ERP, or BI tools.

• Low-level alerts warn you before a tank runs out, so you can schedule a refill instead of an emergency delivery.
• High-level alerts help prevent overfills during deliveries or inflow.
• Rate-of-change alerts flag a level that drops or rises faster than normal, which can point to a leak, theft, or a process problem.

Stationary tank monitor or sensor + gateway: which do you need?

Choose a stationary tank monitor when each location has one tank to watch, and a sensor-plus-gateway setup when one site has several tanks or other assets to monitor.

A stationary tank monitor is the simplest path for scattered, single-tank sites. At busier sites — tank batteries, chemical storage yards, or facilities that also need pressure, flow, or temperature readings — one of our gateways can read multiple sensors through one connection. The F200, for example, accepts RS-485, RS-232, 4–20 mA, 0–5 V, and pulse inputs and is certified for Class I, Division 1, Group D hazardous locations.

Many operators use both, and every device reports into the same LevelCon dashboard. LevelCon brings more than 40 years of industrial monitoring experience, with over 150 customers and more than 50,000 monitored assets. Contact us to match the right hardware to your tanks.
