The PulsarGuard acoustic sensor range offers reliable solids flow detection, it detects structure-borne acoustic signals caused by the movement of material. This movement then causes impacts and frictional contact within a containment (e.g. the inside of a pipe). The sensor detects and reacts instantly to changes in solids flow and warns of blockages and foreign object detection, high flow, low flow, or no-flow conditions.

The PulsarGuard series are non-contacting, so they are fastened to the outside of the structure, meaning minimal installation costs and zero shut downtime. The compact design of the sensor means that it can be fitted in the tightest of positions or environments. The high-frequency detection of the PulsarGuard picks up signals that are often undetectable to the human ear and allows the sensor to be used in environments where there is a high degree of machinery or process noise without interference.
