300m Measuring Instruments Steel Ruler Water Level Meter

Descripiton 

The reading and measurement are consist of two parts:
1. Buried part is consists of the water pipe and the bottom cover ( purchase separately )
2.Ground receiving device -water level meter is consist of the testing probe, steel ruler cable, receiving
system, winding plate and other components.

Probe
The probe is made of the stainless steel,and the water resistance contact point is installed internally,when the contact point out of the water,the
receiving system is off.

Steel ruler
The steel ruler and the lead wire are adopt the plastic technology to be the one,so the steel ruler is not easy to get corrosion, and also simplify the 
operation process, the measurement is more convenient and accurate.



Receiving system
It consists of the sounder and indicator light. The sounder gives a 
continuous beep, and the indicator light gives the sharp flash.

Instruction
After the coil has been rotated during measurement, press the power,and put the probe into the water pipe,then hold the ruler,
let the probe moves down slowly.
The sounder will gives a continuous beep when the contact point touches the water surface,then can read the depth at the pipe orifice,that is from the underwater level to the pipe orifice.


A) When the probe touches the water, the sounder beeps, the indicator flashes, then put down the steel ruler slowly, in order to find out the sound carefully or the exactly location of the moment,then we can read the depth from this point to the borehole.

B) The reading accuracy is depends on the timely buzzer determination and the starting position of the indication, the operator
should practices more to make sure the measurement accuracy.
