Portable Steel Cable Ruler Water Level Meter 30-500m to Measure Well Lake or Reservoir Depth

Portable Steel Ruler Water Level Meter 30-500m

1: Summary

This Steel Ruler Water Level Meter is the high accuracy instrument to measure water level. It is commonly used for measuring the water level in wells, boreholes and standpipes. Specially for the observation of the underground water level in hydroelectric project or the phreatic line inspection of the earth-rock dam by people. This instrument can be used under construction, and it also can be used for long term inspection.

2: Structure

Firstly, the material buried underground part composed by the water level pipe and bottom ( optional ) ;

Secondly, the underground receiving instrument composed by the probe, steel ruler cable , the receiving system and wire spool etc.

Probe parts: made of stainless steel, installed the water resistance point of contact inside , when the probe contacted the water, it will turn on the receiving system automatically, when the probe didn’t contact the water , the system will automatically turn off the receiver .

Steel ruler cable section: adopts plastic technology to make the ruler and the cable together , not only prevent the corrosion of steel ruler , but also simplifies the process of operation , it will make the reading more convenient and more accurate.

Receiving system part : composed by the sounder, indicator and peak value indicator , sounder emits a continuous beeping sound , the indicator turns on, the peak value indicated as voltmeter pointer ,

3:How to use

When you measure, loose the wire spool, press the power button, put the probe into water level pipe, hold the steel ruler cable, move it slowly deep down to the the pipe. When the contact of the probe contacted with water level, the receiving system beeper will continuously beeping. Now you can read the depth size in the pipe orifice, that is to say the distance between underground water and the pipe orifice.(If in your site, you can’t hear the beeper due to the high pitch noise, you can observe the indicator and voltage meter

Pls note two points below

A)When the contact of the probe contacted with water level, the beeper will beep, the indicator lights, the voltage meter moves, it means now you need to slow down the steel ruler cable putting, so that you can find the position of the sound or indicate to read the depth size.

B) The accuracy of the reading depends on the judging the beeper or indicator timely, the accuracy of the measurements are relevant to the skill of the operator, pls repeatedly practice or operate

4:Maintenance

Due to limited battery capacity , whenever the measurement is completed , you should immediately turn off the power switch , do not forget ! When replacing batteries, cables required to ruler from the winding drive all down, twist off the front two self-tapping screws , remove the front panel , you can replace the battery .

Probe and ruler cables etc. must be clean after the measurement , and the ruler cable neatly wound on spools , and then placed in the sfte place .

Probe sealing work requirements , no disassemble absolutely . , in order to avoid damage.

The probe found faulty , please send me promptly plant maintenance.

Avoid bending the ruler cable , especially near the end portion of the probe , to avoid damage and breakage.

Probe should be gentle and avoid severe vibration .

5:Receiving and Storage

The instrument should be stored at a temperature of -10 ℃ ~ +40 ℃, humidity less than 80% of the dry and ventilated non-corrosive gases in the room .
