Now the electronic flowrate sensor- is fine but whats the .. funda it follows.please let us know that.. or else could u throw some light on using a photocell diode or LED-with a time piece. please write in something about that.
   now we need an accurate (with minimum error) so we first of all can't employ a human reading the values at rotameter.Thus suggest some electronic devise, with principle behind it... our gas is specifically nitrigen and types like it.
