General description:
Water level 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 (SL60-94)
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.
2 the green button in the panel is test button, when push this button, light on and
buzzing, that indicate the circuit is in good condition. Or else, the circuit have problem or
the battery has no power.
Use method:
In measuring, make the cable reel rotate and push the power button, 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, This time you
should slowly put the cable and look for the right place of the water level and the pipe or
hole's 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-10 ~ +40 ºC,humidity less than 80%,no aggressive gas.
Product warranty: 1 year.
