The    E-M    Flowmeter    tool    is    used    in    the environmental    and    hydrology    industries    to measure   fluid   movement   in   a   borehole.   It incorporates   Quantum   Engineering’s   "EBF" electromagnetic     sensor,     The     instrument measures   flow   rates   using   the   principal   of Faraday's   Law   of   Induction.      The   downhole probe   consists   of   an   electromagnet   and   two electrodes   located   180   degrees   apart   and 90   degrees   to   the   magnetic   field   inside   of   a hollow   cylinder.      The   voltage   induced   by   a conductor    moving    at    right    angles    through the   magnetic   field   is   directly   proportional   to the   velocity   of   the   conductor   (water)   through the   field.   The   tool   is   capable   of   measuring     low   velocity   flow   rates   down   to   less   than   50 ml/min    and    increased    flow    rates    to    40 liters/min,   through   the   tool's   1   inch   inside diameter    sensor.    When    using    the    tool    to measure    low    velocity    flow    rates    a    rubber skirt   is   attached   to   the   outside   of   the   sensor to   block   off   the   bore   hole   and   force   the   fluid to   pass   through   the   1   inch   diameter   opening inside    the    sensor    coil.    The    Compu-View Software   program   is   designed   to   allow   the automatic    collection    of    data    at    selected static     stations     in     the     borehole.     When measuring   faster   flow   rates   the   rubber   skirt is   typically   removed   and   the   tool   is   run   in either   the   static   station   or   dynamic   mode. The tool has no moving parts.
