1. Apparatus for producing and monitoring drop flow, comprising:

  • a drop sensing unit;

    an associated drip chamber having mounting means thereon;

    first means on said drop sensing unit supportively and removably engaging said mounting means of said drip chamber and including alignment means automatically positioning said drip chamber relative to said drop sensing unit while simultaneously restraining said drop chamber against lateral or vertical movement relative to the vertical path of normal drop flow through the chamber, said first means and said mounting means cooperating to restrict said drop sensing unit to use with said associated drip chamber to provide accurate drop flow monitoring; and

    second means on said drop sensing unit engaging said drip chamber at least at a location vertically spaced from said mounting means along said path, said second means cooperating with said supportively engaging first means to exert clamping forces on said drip chamber substantially normal to said path at no more than three regions of engagement.
