GENERAL DESCRIPTION:
This microprocessor based flow meter utilizes an 8 digit liquid
crystal display (LCD). Isolated monitoring locations are also viable
as power is supplied by a five to seven year long-life battery.
The paddle wheel, spinning at a rate linearly proportional to the
velocity of the flow, activates a switch once per revolution. The
time it takes the paddle to rotate, divided into the diameter of
the pipe, results in the flow rate. Flow rate variations from turbulence
are minimized by a microprocessor averaging process. The user can
choose to display the flow rate, the accumulated flow or alternate
between the rate and totalized flow. To retain the totalizer value,
the reset button can be deactivated.
