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.
