Process Flow Protection Sensor

 

Acoustic device used to detect changes in high frequency sound emissions created by materials in motion. Instant reaction to flow rate changes provides protection to plant or warn of other abnormal flow conditions in pipes, supply lines, chutes and feed mechanisms.  The sensor listens to noise caused by minute impacts, liquid cavitation and friction within structures; making it sensitive to the slightest changes in process conditions, but also immune to auditable noise or vibration caused by machinery.  The non-invasive sensor can be installed in minutes without the need to shut down the process and the compact design means it can be fitted in the tightest of position or environments. Typical applications include blocked pipe or chute notification, pump protection and burst filter bag detection.
