The Hydrological Services Point Velocity Display (PVD100) is a small electronic device used to "clean" the signal from a mechanically rotating current meter such as a Price AA or Pygmy meter and directly reads the velocity on the LCD as well as interfacing to a PDA for computation of velocity and discharge.
PVD100 Current Meter Counter, capable of direct calculation of instantaneous and mean velocity. Accepts ratings for 2 fans (maximum 3 equations per fan). Processes signals from rotating current meters such Hydrological Services OSSB1, OSSPC1, or Red Back and displays readings on integrated LCD displays. The PVD100 also interfaces to a PDA via cable or optional wireless bluetooth, and is fully compatible with the USGS "SWAMI" discharge measurement program for PDA's. Wireless bluetooth communications is available as an option. Comes complete with adjustable neck strap (Batteries not included)
