Water Level Meter Operating Instructions
High Quality Groundwater and Surface Water Monitoring Instrumentation
(Page 1 of 2)
Model 101 P7
Notes:
1. Clockwise rotation of sensitivity dial turns meter on and
increases sensitivity.
2. Always set switch to highest sensitivity position, then
decrease if necessary.
Equipment Check
1. Turn sensitivity dial
fully clockwise
.
2. Depress the Battery Test button to test the battery and main
circuitry (does not test the tape or probe).
3. Submerse the probe in tap water. This completes the circuit
and activates the buzzer and light.
The Tape Guide has been designed to:
• Improve accuracy when reading water levels,
• Easily obtain repeatable measurements,
• Prevent tape being cut by well casing,
• Allow the tape and probe to hang straight from the side
of the well.
1. Fit the small end of the Tape Guide onto the edge of well casing
2" (50 mm) diameter or larger.
2. For small reels only, insert the leg of the Water Level Meter
into the hole on the Tape Guide and rest the Water Level
Meter on the side of the well casing. (See diagram above).
3. To store the Tape Guide, simply clip it onto the support
bracket located on the back of the Water Level Meter.
The Tape Guide
Water Level Measurements
1. The P7 Probe zero measurement point is located near the tip
of the probe.
2. For ease of operation the Tape Guide can be used to support
the Water Level Meter. (See diagram above).
3. Feed the tape into and out of the well using the groove in
the top of the Tape Guide. The light and buzzer activate
when the black Delrin tip is submerged and the zero point
is reached. To ensure accuracy, lower and raise the probe a
few times and then record the depth measurement from the
tape at the top of the well.
4. When using the Tape Guide, the measuring point is offset
from the top of casing. To adjust your measurements to the
top of the casing, simply subtract the amount indicated on
the front of the Tape Guide (i.e. 6 cm or 2/10 ft).
