We devised a simple cost effective system that allows anywhere from measuring one point (for liquids) to multipoints (for solids and multi axles) with temperature compensation. It has preset density values for selected products or a user defined density parameter. This airbag weighing system costs less than half to a third of the price compared to anything on the market. Admittedly its no frills but gets the job done!
The whole kit consists of a programmed smart controller, a IP65 fully protected Screen, a cable and transducer, simple to install or refit onto an existing truck.
Below is how a basic air bag system works:
