Guide to Solids Probe Positioning

When installing level measurement equipment on a silo to monitor solid, powder or granular products (for example, cement or sand), one must consider the behaviour of the product to achieve the most reliable results. During transfer operations of bulk solid material to and from storage silos, the shape of the surface of the material changes. This changeability can make a reliable measurement of the product difficult unless the installation of the level probe is in the correct place. Hycontrol probes offer high degrees of accuracy, but achieving the best placement possible is vital to control vessels containing solid products.  


By positioning the level measurement probe at a position of 2/3rd of the silo’s radius, the user will generally have more accurate level readings, taking into account natural conical peaks and troughs that arise during the filling and emptying procedures. As is illustrated in the white paper linked below, the 2/3rd radius position is the point that offers the best available indication of the true content level inside the silo and is the method utilised by Hycontrol installation engineers.
