Accurate Measurement Steel Ruler Water Level Gauge
Instruction
During measurement, after the coil has been rotated, press the
power, and put the probe into the water pipe, then hold the steel
ruler cable, let the probe moves down slowly.
The sounder will gives a continuous beep when the contact point
touches the water surface, then can read the depth of the steel
ruler at the pipe mouth, that is the distance from the underwater
level to the pipe mouth .

Specification
The steel ruler water level gauge provides the most accurate way to
measure the water level, it can be used to measure the water level
inside wells, boreholes and the water level pipes, it’s very
suitable for the underground water level observation in
hydroelectric engineering and manual inspection of the earth and
rock dam body saturation line.
The instrument can be used during construction, and also long term engineering safety monitoring, it complies with the earth dam safety monitoring
technical specifications.
Notes
A) When the probe touches the water, the sounder beeps, the
indicator flashes, then slowly put down the steel ruler cable, in
order to find out the sound carefully or the exactly location of
the indicate moment, then we can read the depth from this point to
the borehole.
B) The reading accuracy is depends on the timely determination of
the buzzer and the indicate starting position. The measurement
accuracy is depends on the operator's proficiency, so the operator
should practices more.
