Chapter 1: System Description
Function and Theory
The Keck Water Level Meters are portable instruments used to accurately
measure water levels in monitoring wells and bore holes. The meter
detects water levels with a 5/8” O.D. stainless steel weighted probe
attached to a polyethylene tape marked to 1/100th of a foot.
The meter relies on fluid conductivity to determine the presence of water.
An audible signal and visible LED light activate when the probe contacts
water. The meter incorporates a sensitivity adjustment to prevent false
triggering.
To avoid damage to tape and strain relief, do not over
tighten reel with probe in storage position.
