Rickly Hydrological 102-020 AquaPulse Impulse Counter Timer

The AquaPulse 102-020 is an updated LCD impulse counter with timer display which registers the number of revolutions made by the bucket wheel or propeller of a current meter. The counter eliminates the need to count every revolution during a velocity observation. The time display also eliminates using a stopwatch and allows both meter counts and time to be read easily and quickly. For use with Universal/AA/Pygmy current meters.
