The VM400 flow velocity measuring device is a compact and space-saving device solution for continuous point-to-point measurement of the air velocity in road and railway tunnels or comparable traffic infrastructure constructions. The VM400 can be assembled easily at nearly any point on tunnel walls. The measured values and status information are transmitted to a monitoring system via the integrated analog or digital interface, as wells as via an Ethernet interface in the VM400E variant.At a glanceModern ultrasonic technology for non-contact measurementLarge measuring rangeCompact device designVery easy mounting and commissioningImmune to contaminationYour benefitsMinimal wear and long maintenance intervalsReliable measurement even at low air velocityLow investment costsMinimum installation costsEasy integration into monitoring systems
