Tank Gauging for Bulk Plants

Radar Tank Gauging is a suitable solution for tank level monitoring in the fuel and oil storage market.   If you operate a bulk storage facility and need a cost efficient method to monitor inventory levels then Rollie Systems has the answer.

In a typical bulk plant the cost of installing a system is usually close to the cost of the equipment itself !  Our system is completely wireless, there is no additional cost for an electrical contractor to run conduit and pull cable, a very large expense in most cases.

We are committed to providing you with a low cost, reliable system that allows complete control over product management.

Level Monitor & Controller

The system consists of a Tank Monitor, a Controller unit and a host software package.  This solution allows you to have an accurate reading of tank levels, and saves you money by allowing for efficient and cost effective delivery scheduling.

With our system you will have safe, reliable tank gauging for your local or remote site storage tanks.  All models are battery powered and classified as Intrinsically Safe.

Since the tank gauges are battery powered and wireless, you won't need to change anything about your storage site.  No expensive wiring and conduit needs to be installed and the gauges batteries will last for over two years.

Level Monitor consists of a hermetically-sealed plastic enclosure that houses the impulse generating sensor and RF telemetry circuitry, a battery compartment, and a flexible wire probe.

The principal behind the Monitor is based on a novel form of radar known as MIR (Micro-Power Impulse Radar) or Ultra Wide Band (UWB) Impulse Radar. In operation, a very short, very low energy electromagnetic impulse is generated from the top mounted sensor down a thin wire (probe) that is immersed in the fluid.

The sudden change in the dielectric at the fluid surface causes some of the impulse energy to be reflected back up the probe. The time difference between pulse reflections and the maximum calibrated time delay is proportional to the level of the fluid. This information is then relayed to the Controller via the wireless radio (RF) link.
