Top 7 Things to Consider When Purchasing A Water Level Metre

Choosing a reliable water level metre might be challenging, especially if it’s your first time. Many industry personnel use water level metres to determine the depth of water in wells, boreholes, standpipes, and tanks. Today, we’ve put up a one-stop-shop for everything you need to know about buying a water level metre.

1. Under field conditions, a water level metre should be accurate to within 5%

Before you buy a water level metre, be sure it’s calibrated. This demonstration should have an accuracy of at least  2%, allowing for some degradation and loss of precision before it starts to slip outside the  5% range.

2. The meter should be tamper-proof

You should get a tamper-proof water level metre. Unauthorized interference should be immediately observable to alert you to the possibility. You may also get a wind-resistant metre that doesn’t “bend” in the wind and gives you more precise readings.

3. Self Contained

You should choose a self-contained water metre. There should be no need for external power or ground. The majority of those that run on batteries are appropriate.

4. Easy to read

The water level metre you’re thinking about should be able to offer both instantaneous and totalized flow rates. The ratings should be easy to use and understand. The level markings should be precise and permanent, and they should not fade after a few uses.

5. Probe

The probe should be made in such a way that it minimises or eliminates issues with cascading water. The probe should be able to submerge below water and measure groundwater as well. It should perform better in both cascading water and water with low conductivity.

6. Longevity

You should also consider how long water level metres last on average. This is primarily dependent on the metre type, the circumstances in which it is used, and the individual utilising it. You should consider changing your water metre once you notice a decrease in accuracy before it falls outside the  5% level.

7. Cost

Water metres are generally more expensive the more accurate and reliable they are. While the buying price is important, it should not be the only factor to consider. Before making a final selection, consider the costs of maintenance, data gathering, and calibration.

So, those are the top seven things to think about when buying a water level metre. What aspects would you consider before purchasing one? In my opinion, it is up to you depending on the circumstances. Thus, it is best to make some homework before you purchase a water metre.
