Water Level Meter

The steel ruler water level gauge provides the most accurate way to measure water levels, used to measure the water level in wells, boreholes and water pipes, particularly suitable for the observation of groundwater level in hydro power projects and artificial inspection of dam body infiltration line. The instrument can be used during construction, but also as a long-term safety monitoring with the project, complies with earth dam safety monitoring technical specifications.The steel ruler water level gauge provides the most accurate way to measure water levels, used to measure the water level in wells, boreholes and water pipes, particularly suitable for the observation of groundwater level in hydro power projects and artificial inspection of dam body infiltration line.

Principle structure

There are two major componentsaboutthe measurement of water level variation :

1.Buried underground material iscomposed of water pipe and the bottom cover (additional purchase)

2.Ground receiving equipment-steel ruler water level gauge,including the probe, steel ruler cable, receiving system and winding plate and other components.

Probe part:Made of stainless steel. Install the water resistance contact point in the internal, when the contact point comes into the water, it will turn on the receiving system, once left the water, it will stop.

Steel ruler part of the cable: Made of steel ruler and wire byplastic technology, which prevents the steel ruler corrosion, but also simplifies the operation process, to make reading more convenient and accurate.

Receiving system part:Consist of the sounder, indicator and peak indicator . The sounder gives a continuous beep,then the indicator light is on, and the peak indicates the voltmeter.


Usage method

When the reel is freely rotating, press the power button, then put the probe into the water pipe,at the same timehold the ruler cable, so that the probe slowly move down. When the contact point comes into contaction with the water, the sound devicewill be issued a continuous beep.At this point read outthe depth of the steel ruler at the nozzle, that is the distance from the water table to the pipe mouth . (If the noise is measured in a relatively large environment, the buzzer can not hear,then observeindicator and the voltmeter.)

Users must pay attention to two points:

A) When the probe contacts come into contact with the water, the sounder will sound, the indicator and the voltmeter pointerstart to working. At this point should be slowly put steel ruler cable, in order to carefully find the pronunciation or indicate the exact location of the moment.

B) The accuracy of the reading depends on the timely determination of the buzzerand indicating the starting position.The accuracy of the measurement and the operator's proficiency should be repeated practice and operation.
