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.

Chapter 2: System Installation
Manual Reel
Carefully lower the probe into the well, using the tape guard to prevent
damage to the tape.
In wells larger than 4” be careful not to let the tape scrape against the lip
of the well casing.
Electric Reel
1) Plug power cord into the control box of the reel.
2) Attach red clip to positive battery terminal, and black clip to the
negative battery terminal.
3) Turn the speed control dial fully counter-clockwise. Press desired
button (up/down). Slowly rotate the speed control until reel is rotating at
the desired speed.
Do not use the tape guard in wells larger than 4”, as
it may fall down the well.
When winding the tape up on the reel, pay careful
attention so that the tape and/or probe do not get
caught or tangled.
Keep hands and loose article of clothing away from
chain. DO NOT operate unit without guard!

Chapter 3: System Operation
1) Turn the instrument on with the ON/SENSITIVITY switch. If the
buzzer makes a loud signal and the light is visible, the battery is
adequate for normal operation.
2) Lower the probe down the well to the water surface. The light and
buzzer will activate. At this point, adjust the probe sensitivity dial by
rotating it counter-clockwise until the light and buzzer shut off.
3) With the probe still in contact with the water, adjust the probe
sensitivity dial clockwise until the light and buzzer barely activate. In
this setting, the probe will detect water levels but will not be affected
by false triggering.
4) Water level measurements can now be taken from the top of the
casing or any reference point.
5) The meter should be stored with the switch in the OFF position. If
the meter will be stored and not used for three (3) months or longer,
remove the battery to prevent battery leakage from damaging the
meter.
To avoid damage to tape and strain relief, do not
over tighten reel with probe in storage position.

Chapter 4: System Maintenance
Battery Replacement
Replace the battery when the audible and visible signals become weak or
the unit does not operate.
Step 1 Gently remove the battery tray.
Step 2 Remove the old battery and replace it with a new one.
Cleaning
The Water Level Meter can be cleaned with any detergent such as
trisodium phosphate (TSP), Alconox or Liquinox. If other detergents are
used, take care to select detergents that are compatible with Teflon®,
polyethylene, and stainless steel. The reel should not be submerged in
any liquid, but may be cleaned with a damp cloth.
If the probe becomes covered with silt or mud, it may be cleaned with
detergent and a soft bristle brush.
Be aware of the polarity (+, -) of the battery when
placing the new battery in the tray.

Chapter 5: System Troubleshooting
PROBLEM: NO SIGNAL (audible or visible) WHEN UNIT IS
TURNED ON.
Solutions:
1) The battery is discharged.
•Check or change battery (see page 8).
2) The circuit is malfunctioning.
•Consult the manufacturer.
PROBLEM: NO INDICATION OF WATER.
Solutions:
1) The conductive contact is dirty.
•Clean the contact (see page 8)
2) There is an open connection in the tape.
•Replace tape and/or probe. **
3) The circuit is malfunctioning.
•Consult the manufacturer.
PROBLEM: THE SIGNAL (audible or visible) IS INTERMITTENT.
Solutions:
1) There is an open connection in the tape.
•Replace tape and/or probe. **
2) There is a loose connection in the circuit or the probe.
•Repair the connection. **

10
PROBLEM: The signal (audible or visible) is continuous when
not in water.
Solutions:
1) The conductive contact is dirty (causing bridging).
•Clean the contact (see page 8).
2) There is a short in the tape and/or probe.
•Replace tape and/or probe. **
3) The circuit is malfunctioning.
•Consult the manufacturer.
