Water Level Indicators

Simple, effective direct reading.

Application

Measure water levels in standpipes and wells.

Operation

The water level indicator consists of a probe, a graduated cable or tape, 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 cable or tape.

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.
• 1/100' 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. Compact six-inch reel has a handle. Larger reels have stand.

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.
