The Model 6505 Miniature Current Meter is a smaller scaled Ott-type meter for use in shallow streams and canals with a wading rod. Its range of operation is 0.1 to 19 feet per second (0.03 to 6 meters per second) with multiple propellers. The Model 6505 Miniature Current Meter consists of a streamlined body which houses the sensing mechanism, an encapsulated reed switch and the horizontal axis propeller shaft which has a permanent magnet mounted such that each rotation of the shaft produces a pulse from the reed switch. The pulses are conducted through a lead to the surface wher
e they are counted by a Current Meter Counter. The velocity of the stream is proportional to the rotations of the propeller. Each Model 6505 comes with a type 1, 3, or 5 propeller, instrument case, oil and tools and is provided with a calibration certificate and rating table (Bargo and Barel). Current meter counter is sold separately.

Features - The Model 6505 design offers: 
 Streamlined nickel silver body 
   Low Start Velocity - signals are generated by a magnet impulse device with no mechanical retardation of the propeller 
   Ease of replacement of the reed switch assembly 
   Encapsulated reed switch to resist damage from dropping or knocking
