The ROSSMA IIOT-AMS Dry Contact VPM switching-measuring device is an innovative device designed to monitor the condition of non-electrified shut-off and control valves at various industrial facilities. It comes in two versions: general industrial and explosion-proof. No cable lines, quick installation and commissioning, low cost, and long autonomous operation life. The equipment can operate on two wireless network standards: LoRaWAN or NB-IoT. Once a day, the switching-measuring device transmits information about its current status, as well as upon each opening/closing event. The dispatcher’s SCADA display shows the percentage ratio of valve opening/closing.
