Product Description

Water Level

Water Level Meter Application


This Steel Ruler Water Level Meter is the high accuracy instrument to measure water level. It is common used to measure the water level in wells, boreholes and standpipes. The depth is to 900 meter.


System compose


The system composed of sonde, ruler cable, the receiving system and reel, etc


1. Sonde: Stainless steel, inside mounted the water resistance point, when the point touch the surface, the receiving system will be turned on, when the contacts out of the water, the system will automatically turn off.


2.Ruler cable parts:  Together with the ruler and wires, with good function of corrosion resistance, Oil resistance, microbes resistance.


3. Receiving system: composed of the sounder and peak indication. When the sonde reach to water, the water completes an electrical circuit powered by a 9v battery, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading off the cable at the top of the borehole, casing or tube, and then measuring off to the nearest mark.


4. Reel: composed of wire spool and holder, the receiving system and battery  are mounted inside the wire pool. Outside the wire pool, the ruler cable is on it.

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.

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)

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 cannot bucking,especially the ends. The detect head should carry and put softly and avoid vibration.

Customer should open the box and check the product when you receive it.
Storage temperature-10~+40℃,humidity less than80%,no aggressive gas.
Product warranty:1year.
