WL500 Water Level Sounder

Global Water’s WL500 Well Level Sounder sets a new precision standard for well water level measurement. The Water Level Sounder meets or exceeds federal specification US GGG-T-106E (USA) or EEC CLASS II (Europe) for a guaranteed accuracy of 0.008%.

• Overview

  Global Water's WL500 Well Level Sounder is ideal for detecting water levels and well bottoms with high precision. It is provides trouble free operation in wells with falling water and heavy oils slicks, even if the well is not cased.

  Key Features:

  • Precision measurement, simplicity, and durability
  • Polycarbonate sturdy reel
  • Durable polyester powder-coated steel frame
  • Corrosion-resistant stainless steel fittings
  • Large, ergonomic brake and soft grip vinyl winding handle
  • Water and dust-proof encapsulated electronics
  • Strong and accurate NTS certified tape with stainless conductors
  • Full depth stainless steel and Teflon probe
  • Long lasting flexible link between the tape and probe
  • Tape marked in 1 foot and 0.01 foot intervals with up to 2000 feet in length
  • Audio alert beeper and LED indicate contact with the water

   

  The Water Level Sounder uses a full depth-rated stainless steel and Teflon probe that is 5/8-inch (16 mm) in diameter. The water level sounder's sensor electronics are encapsulated in a water and dust proof housing. The water level sounder's electronics module can be removed so that the entire reel and tape can be cleaned and decontaminated. The flat spring steel core ensures that the level sounder will hang perfectly straight in large and small diameter wells. This provides unparalleled accuracy when compared to the flat white tapes, where kinks in the tape introduce slight errors, in addition to the displacement of water changing the static level.

  When the water level sounder's probe assembly makes contact with the surface of the water, a bright LED glows and a beeper sounds on the reel. The water level sounder detects the bottom of the well using a specially engineered tip that causes the sounder's audio alarm to cease when the bottom of the well is reached.

  The well level sounder consists of a strong NTS-certified polyethylene jacketed measuring tape that will accurately read to 0.01 foot or 1 mm. The tape reels are built of resistant polycarbonate (or, for units with over 400 ft cable, of lighter aluminum

  The depth sounder is battery operated, thus there is no danger of shock from an outside power supply. Two conductors make a separate ground connection unnecessary, so the instrument will function equally well in uncased test holes or in uncased wells in rock. Water entering the well from casing leaks or perforations about the water level will not affect the depth gauge's measurements.

• FAQs

  What makes the WL500 different from other YSI water level instruments?

  • The WL500 is a water level sounder used for well water level monitoring.
  • The WL500 utilizes the highest quality tape on the market along with a field-replaceable sensor.
  • The product is battery-powered and will notify the user when the sensor has made contact with the water.

  What applications is the WL500 best suited for?

  The WL500 is a well-level sounder best suited for aged wells, where you need to measure the depth and level of water within that particular well.

  Ideal for wells that may be crooked, have internal debris, or well intrusions.

  How will I know when I have reached the well water depth?

  The WL500 contact sensor will make a noise and the LED sensor will light up and once contact is made with well water reel in the tape and record your well depth

  What type of tape lengths are available?

  Tape length ranges: 100’, 200’,300’,500’,650’,750’,1000’, and 2000’

  Why use the WL500 well sounder over the WL650 Sonic Water Level Meter?

  The WL500 is ideal for aged wells that are not entirely straight, have debris, or have any well intrusions.

  Whereas the WL650 is ideal for wells that are typically straight with little debris to interfere with the unit.

  What are my power requirements?

  Standard 9 Volt battery

  Does the WL500 have datalogging capability?

  The WL500 does not have the ability to record data but is extremely easy to use in the field for onsite measurements.
