The AMETEK Drexelbrook CheckWell™ water well level sensor automatically monitors the level or drawdown in water wells up to 3000 feet (914m) deep. It generates a continuous linear output signal that is directly proportional to the well level. This output can be used for remote monitoring/recording, warning signals, and pump control via optional current-actuated relays.
The advantages include quick installation, no manual maintenance, and an all-electronic design for exceptional reliability. Density variations, mineral or oil deposits on the sensing feature, and oil on top of the water do not affect the device.
