Taking Advantage of a 3/8" diameter high integrity Level Sensor.
With the current awareness and concern over the environment, there are increasing demands for the monitoring and control of the planet's water. One of the most common methods is by the use of deep wells drilled into aquifers. Some of these may be many thousands of feet below the surface, although most are only a few hundred feet. Such wells can be purely for water monitoring or considered as production where water is pumped out for human or industrial consumption. The purpose of this short article is to focus on the level measurement which, over time, can lead to valuable information regarding the capabilities of the well, changes in gradients, or flow direction and the aquifer condition. The cost to instrument a well can vary from a few thousand to tens of thousands of dollars depending on the measurements required. The initial cost of actually drilling the well is one thing, but installing and extracting the instrumentation remains an additional cost often requiring special equipment. Therefore, the ease of changing measuring instruments is important, but long term reliability is even more so.
