Abstract

A flow meter having a magnetic base sensor for electrical feedback of flow rate is disclosed. A float rod carrying an indicator and a magnet moves within the flow meter body with and the flow being visually read and electronically read.

Claims

1. A float type flow meter, said flow meter including a housing, a tubular guard extending downwardly from the housing, a tubular sight glass contained within the confines of said guard;

a float rod assembly axially movable within said tubular sight glass responsive to fluid flow;

said float rod assembly including;

a float rod having a first end and a second end;

an indicator located on the first end; and

a float stop body located intermediate of said first end and said second end;

a magnet attached to said indicator and being cooperatively coupled with one another to move in unison with one another responsive to fluid flow;

a magnetic base flow sensor having a magnetic sensing rod for electrical feedback of fluid flow rate; and

means for visually viewing relative fluid flow rate and comprising a scale plate positioned adjacent said tubular sight glass and for relative location with said indicator.

2. The flow meter set forth in claim 1 including an electrical convertor box responsive to said fluid flow rate.

3. The flow meter of claim 1 and further including an electrical convertor box for “

stand alone”

installation.

4. The flow meter of claim 1, wherein the diameter of said indicator is smaller than the inner diameter of said sight glass.

5. The flow meter of claim 4, wherein the distance between the diameter of said indicator and the inner diameter of said sight glass allows free movement of the indicator.
