  Hydrometer  \Hy*drom"e*ter\,  n.  [Hydro-,  1  +  -meter:  cf  F. 
  hydrom[`e]tre.] 
  1.  (Physics)  An  instrument  for  determining  the  specific 
  gravities  of  liquids,  and  thence  the  strength  spirituous 
  liquors,  saline  solutions,  etc 
 
  Note:  It  is  usually  made  of  glass  with  a  graduated  stem,  and 
  indicates  the  specific  gravity  of  a  liquid  by  the  depth 
  to  which  it  sinks  in  it  the  zero  of  the  scale  marking 
  the  depth  to  which  it  sinks  in  pure  water.  Extra 
  weights  are  sometimes  used  to  adapt  the  scale  to 
  liquids  of  different  densities. 
 
  2.  An  instrument,  variously  constructed,  used  for  measuring 
  the  velocity  or  discharge  of  water,  as  in  rivers,  from 
  reservoirs,  etc.,  and  called  by  various  specific  names 
  according  to  its  construction  or  use  as  {tachometer}, 
  {rheometer},  {hydrometer},  {pendulum},  etc.;  a  current 
  gauge. 
 
  From  WordNet  r  1.6  [wn]: 
 
  hydrometer 
  n  :  an  instrument  for  determining  the  specific  gravity  of  a
