The OTT C31 Universal Current Meter is a portable flow / velocity meter designed to capture measurements from either in-situ hand-held wading rods, or cable based applications, such as cable a suspended from a bridge or boat. It is perfect for the flow / velocity measurement of rivers, open drainage, or pipelines.
The OTT C31 is connected to a compact OTT Z400 digital counter that records the number of propellor revolutions by measuring electrical impulses.
