James F. Guthrie is a notable inventor based in Tempe, AZ (US). He has made significant contributions to the field of fluid measurement technology. With a total of 2 patents to his name, Guthrie's work has had a considerable impact on the industry.

Latest Patents

Guthrie's latest patents include innovative designs for turbine flowmeters. The first patent describes a turbine wheel that is insertable in a line to intercept fluid flowing through it. A pickup coil senses the rotation of the turbine wheel. When the speed of rotation exceeds a predetermined safe limit, the turbine wheel's speed is reduced by turning it 90 degrees to the direction of fluid flow. The second patent also focuses on a turbine flowmeter, where the turbine wheel's rotational speed is reduced to zero by the closure of a gate that prevents further fluid flow. This gate comprises a sleeve that covers the housing in which the turbine wheel resides. In one embodiment, two turbine wheels with different rotational characteristics are alternately gated open and closed, depending on the fluid velocity.
