Density measurement in concrete residual water
The development of the OLAS measuring system, an online measuring system for determining the solids content of concrete recycling water, began almost ten years ago. Today, a reliable and economic measuring system is available that has reached series production maturity. The OLAS is named after its function: ‘Optical Light Absorption Sensor’. The OLAS makes use of a sophisticated infrared absorption measuring method, in which the measurement light is introduced into the medium via optical fibres. If desired, the OLAS can be supplemented by the OLASTPC (OLAS Touch Panel Controller), an optimal evaluation, display and control unit, to form a complete measurement system.
