300m Water Level Sensor Water Level Indicator Borehole Dipper Ruler Water Well Level Meter Electronic Dipping Tapes Flat Tape Water Level Meters

This kind of Water Level Indicator Instrument is the high accuracy instrument yo measure water level.It's common used to measure the water level in wells,boreholes and standpipes.The depth is to 900 meter.

>>System Compose of the Water Level Meter:
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 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.
