When it comes to monitoring your water levels, sonic technology may seem to be a good option, however, these pricey devices are not nearly as accurate as tapes! Sonic technology is limited due to several different factors.
What Causes Sonic to be Inaccurate and Limited?:
- not all well casings are perfectly straight, and may result in a false reading.
- readings can also be affected by fractures in wells which result in cascading water in a well
- interference from roots/pumps/cables and other debris in the wells or boreholes can cause false readings
- sonic water level meters can only work on wells that have a diameter less than 10″
- only work to detect the surface of the water
Advantages of Water Level Meter Tapes:
- the Heron dipper-T with optional Well Depth Indicator Probe attached, is used to accurately indicate the full depth of the well
- tapes have a much more accurate and easy to understand reading
- the non-stretch, flexible steel tapes can withstand years of use
- steel tapes are manufactured to ASME certifications
- Kynar or Polyethylene coated tapes
- tape markings underneath coating ensures long-term readability
- tapes can easily be adjusted if caught on an obstruction in the well
- audible and visual indicator for both static and drawDown modes
- tapes are available in both metric (cm) and imperial (engineering scale)
- in cases of cascading water in a well, users can adjust the sensitivity of their water level meter to ensure accurate readings when reaching the actual water level
When looking for the most accurate and cost effective way to measure your water levels, there is really only one option. Tapes are far more reliable and accurate when it comes to measuring water levels.
