General description:
Ruler water meter provide an accurate measurement
method of level meter, usually used for the measurement
of water level in the drilling holes or water level
pipe ,particularly suitable for hydropower engineering
underground water level or artificially inspection dam
observation. This instrument can be used in
construction period, but also can be used as the
long-term safety monitoring project. comply with the
dam safety monitoring technology standard (SL****4)

Working principle:
The measurement of the water level by the following two
parts:
1. Underground material, it is composed by water level
pipe and bottom cover (not include in the system, it is
need purchased separately)
Ground receiver-ruler water level meter, it is composed
by detect head, ruler cable, receiver system and cable
reel.
Detect head: made by steel, inside is a water
resistance contact point. When the contact point
contact water, the receiver system will open, and when
the contact point leave the water, the receiver system
will close.
Ruler cable: it made by ruler and cable, and use
plastic technology keep them together, and avoid the
steel corrosion and simple the operation, make the read
more convenient and accurate.
Receiver system: it is composed by sounder, indicate
light and peak value indicator, peak value indicate is
voltage indicate.
Use method:
In measuring, make the cable reel rotate and push the
power , put the detect head in the water pipe,
put the ruler cable in hand and make it drop slowly.
When the detect head contact point contact water, the
receiver system buzzer will sound. Then you can read
the data of the ruler cable and can know the water
level.(if the surrounding voice is loudly, maybe you
can hear buzzer, so you can observe the indicate light
and voltage meter)
User should notice the following two points:
1. when the detect head contact water, buzzer will
sound, indicator light on, voltage meter needle rotate.
This time you should slowly put the cable and look for
the right place of the water level and the pipe or
holes depth.
2. The accuracy of the indication, which depend on the
judge the right place which the buzzer and indicator
light on. So practice of the operation is very
necessary.
Maintenance:
Because the system use battery to supply power, so when
you finish test, you should keep it power off. Power
supply is 9V, when it has no power, you should open the
cover and change it.
After measurement, please keep the detect head and
cable clean, cable rolled in cable reel. And put them
in a good condition.
Unauthorized disassembly of the product, it can not put
in water horizontally, the cable can not bucking,
especially the ends.
The detect head should carry and put soft and avoid
vibration.
Storage:
Customer should open the box and check the product when
you receive it.
Storage temperature**0 ~ **0 °C,humidity less than
*0%,no aggressive gas.
Product warranty: 1 year.
