Patent ID: 7729869

Claim:
An electronic flow meter connectable in-line with a piping system for indicating flow characteristics of a known fluid flowing through the piping system of known internal diameter comprising: a) a flow meter body having a flow passageway extending therethrough; b) an electronics assembly mounted directly on said flow meter body and including a processor, a power supply, a display, a temperature sensor and a flow rate sensor; said temperature sensor communicating a measured temperature indicative of the temperature of the known fluid flowing through said flow passageway to said processor and said flow rate sensor communicating a measured value indicative of the flow rate of the known fluid flowing through said flow meter to said processor; said processor programmed to calculate a calculated flow rate using the measured value; and said processor programmed to calculate a calculated Reynolds number associated with the known fluid flowing through pipe of the known internal diameter at the measured temperature and the calculated flow rate; said processor programmed to compare the calculated Reynolds number versus an established Reynolds number indicative of whether laminar flow exists and to display a laminar flow indicating icon on the display if the comparison determines that laminar flow exists.
