The FLOWSIC60 makes use of the ultrasonic signals to determine accurate air velocity in tunnels and shafts. Composed of high-quality stainless steel components, this device is renowned for its durability and ability to perform in adverse environmental conditions. As soon as it is installed, the FLOWSIC60 starts measuring air velocity across the entire tunnel cross section. It displays the results via the analog output. This feature makes it simple to integrate this device with the monitoring systems. The FLOWSIC60 is equipped with state of the art safety features and it has been certified for mining use by IECEx. Some of the noteworthy features that make it extremely effective are low maintenance, integrated self-monitoring and efficient operation in difficult surroundings. It also provides for air flow measurement in explosion proof areas.
