How does Drain Gauge Measure the Volume of drainage? A dielectric water level monitor in the center of the reservoir measures the water level to 1 mm. There are no moving parts. What is the divergence control tube? The divergence control duct assures that soil moisture is neither lost nor accumulated once the downwelling soil water approaches the wick. Why the wick? The bottom of the divergence control duct creates a boundary where the water will not move. By installing a wick at this location the wick creates a suction which facilitates the water ® movement down to the reservoir.
