Mechanical current meter
This small, lightweight mechanical current velocity meter has a measuring range of approximately 0.1 m/sec. to 7.9 m/sec. The meter is used for current velocity measurements in rivers, channels, sewage systems, pipes, etc. Suspended from a wire the meter can be applied at great depth. The meter is balanced in such a way that it will remain in a horizontal position even if the meter for instance is pulled at speed by a line. The propeller is linked directly to a six digit counter that registers and visualizes every single rotation of the propeller, similar to the mileage counter in a car. The counter is placed within the instrument. After retrieval it is possible to read the overall number of rotations of the propeller on the counter through a clear synthetic window. The meter can be mounted to a wire as well as to a telescopic rod (with an extended length of 2.4 meter).
