Aggregate Plant Relies On Radar Level Transmitter For Inventory Monitoring In Silos


An International Aggregates Company has a diverse business which includes aggregate products they mine at their own quarries to produce ready mix, asphalt, liquid asphalt and recycled concrete products. The company also provides management services for the construction industry, including major road projects. For these projects, the company uses aggregates and fly ash in processing products for use in building roads. The aggregates and fly ash are kept in large silos.

The company must make sure they have adequate supplies of their raw materials on hand in the silos. Previously, they would check the silo inventories using a manual measurement.

The local Siemens representative suggested the customer try the SITRANS LR260 continuous radar transmitter for measuring the product levels in their silos. The customer was convinced the Siemens radar instruments could do the job and purchased seven of the level transmitters for their aggregate product silos. All of the units are connected to SITRANS RD500 remote data managers to provide integrated web access, alarm event handling and data capture for the transmitters.
