Abstract:
A water flow detector comprised of a check valve and parallel flow detection loop in which flow can be measured by monitoring the pressure differential as the difference between the water supply line pressure at the tee on the inlet side of the check valve (high pressure side) and the low pressure being at the tee connection on the downstream or outlet side of the check valve. The proportional water flow in the loop acts on a float which position is detected by optical and electronic means and enables the recognition of very small flows (small leaks) triggering an alarm to signal the leak.

Claim (Index 1):
I claim a unique water flow detector piping loop device, WFD01, comprising a vertical-oriented inverted U-shape loop with means of detection, for detection of downstream flow in a water line;\n a) using the resulting differential pressure and proportional flow in the loop when it is connected in parallel with a spring-return type check valve installed in the water line; b) acting on a float in a clear-wall pipe float chamber part of the loop by the flow differential pressure force to position it upward against gravity; c) the loop piping and float being sized so most of the loop differential pressure is across the float which position (at less than 0.5 inches water column, not affected by water line static pressure) is detected by optical and electronic means to turn on blinking light; d) detecting (raising an alarm) for very small flows before flow and differential pressure is high enough to open check valve, continuing to alarm for larger flows as when check valve is open; and e) the vertical orientation of the piping loop allowing all parts of the WFD01 to be contained in a 4\u2033 PVC pipe vertically oriented cylindrical housing for protection and arranged so the bottom part can be below ground for installation with the check valve and top part is above ground so the alarm light is visible.
