Water Level Sensor Features

Waterra WS-2 Water Level Sensors Features

  • auto shut-off
  • sensitivity adjustment
  • rugged modular construction
  • powered by 4 AA batteries
  • membrane ON/OFF switch
  • extremely low power consumption
  • sensor’s probe is 5/8″ diameter and is constructed from 316 stainless steel. The probe is snapped into the side of the reel in a probe holder when not in use.
  • dog bone polyethylene tape cross-section design prevents adherence to wet surfaces such as well casings
  • metric tapes are graduated to the nearest millimetre
  • imperial tapes are graduated to the nearest 1/100 of a foot
  • PFSA free

WS-2 Open Reel

The WS-2 line of Water Level Sensors use tough, plastic reels to protect the stainless steel tape from damage and dirt while the tape is stored on the reel.

The WS-2 Open Reel is available with tapes in metric units of 30, 50, and 100 meters or 100 or 250 feet. The tapes are polyethylene coated and are PFAS free.

Special orders are possible and best to contact us to discuss your needs and timing.

WS-2 Faceplate Features

When the WS-2 is turned on, the battery light will be illuminated continuously. Low batteries are indicated by a flashing signal from the low battery light indicator.

When the WS-2 water level probe contacts water, the buzzer will emit an intermittent tone and the water indication light will illuminate.

In some groundwater conditions, the probe may not adequately detect the water in the well. This may be caused by low salinity. When this happens, the sensitivity of the unit can be adjusted by rotating the sensitivity adjustment knob located on the left side of the front hub panel.

WS-2 Faceplate Features

  • membrane ON/OFF switchwith an automatic power saving feature that will turn the unit off after three minutes
  • water indication light LED display that illuminates when water is detected
  • loudest buzzer available was chosen for these sensors to ensure that the units could be heard in noisy environments.
  • sensitivity adjustment potentiometer allows the unit to be set specifically to a wide range of water salinities, allowing the user to dial out the false readings caused by cascading water
  • low battery indication light
  • battery pack is located on underside of faceplate

Adjusting The Conductivity Sensitivity Setting

In order to allow the WS-2 Reel Case to detect water of various salinity, the design includes a sensitivity adjustment knob. This knob is located on the left side of the front hub panel.

In monitoring wells where excessive bridging is experienced, the knob should be rotated to the left. Where water of low salinity is suspected, the knob should be rotated to the right. The optimum setting is obtained by adjusting the control knob to the point where the WS-2 is no longer emitting the water signal while the probe is immersed in the well. Then rotate the knob back in the opposite direction slowly, stopping when the water signal begins again.
