Water Level Indicators

Simple, effective direct reading.



Measure water levels in standpipes and wells.


The water level indicator consists of a probe, a graduated cable, and a cable reel with built-in electronics. The probe is lowered down the standpipe until a light and buzzer indicate contact with water. Depth-to-water measurement is read from the cable.

WLI with Laser-Marked Cable

  • Laser-marked cables offer clear, high contrast inscriptions that are a permanent part of the cable jacket. The marks cannot be rubbed off or washed off and are as resistant to solvents as the cable jacket.
  • 0.01 ft or 2 mm cable markings provide convenience and accuracy.
  • Small diameter, round cable minimizes friction on casing walls.
  • 3/8" probe fits small diameter pipes. When not in use, probe clips to cable reel.
  • Bright LED and piezoelectric beeper signal contact with water.
  • Low power circuits provide long battery life. Indicator shuts off power automatically after 10 minutes.
  • Durable reel features 1/8" aluminum walls and bronze bearings. The compact seven-inch reel can be equipped with either a handle or a stand, while the larger reels have stands. Laser Marking Machine

The photograph at right shows a water level indicator cable being drawn through the laser marking machine. The machine directs a laser beam at the cable jacket. The jacket changes color where the beam strikes, and the resulting marks and characters become a permanent part of the cable jacket.
