Magnetic Inductive Flow Sensors for Concrete Batching Systems
In many regions the quality of concrete is considered as a security-related attribute. Therefore the need to monitor and to record its properties over the whole supply chain becomes increasingly important. The amount of water and the quantity of additives determines the quality of the concrete.
High accuracy is often content of national standards for ready-mixed-concrete production.
Influence of transportation and additives on concrete quality
A trucking company transports the concrete-batch from producer to contractor. Although the concrete was mixed correctly in the factory, it may arrive at the construction site with a different composition that no longer meets the quality requirements. In order to be able to transport the ready-mixed concrete over longer distances, additives are added In-transit Concrete Management Systems maintains the consistency (slump) of concrete during transport by truck. It adds water and admixtures to the load automatically. A flow sensor measures the water and additive quantities and transmit them to the control unit, which logs all values.
Reliable flow measurement is therefore very important. Defective flow sensors render the entire load unusable and cause longer downtimes for the truck.
