OCT-WL-500 Well Level Sensor
A submersible pressure sensor reading water level to 200 m depth, accurate to ±0.25% of full scale.
It is lowered into the well on an armoured cable and measures the water column above it. With barometric compensation it reports a true level rather than a reading that moves with the weather.
A 15-minute sample is what draws the drawdown curve: how far the level falls under pumping, and how long it takes to recover afterwards. The second figure is the one that says whether the well is being drawn down faster than it recharges.
What it includes
-
Up to 200 m water column
-
Barometric compensation
