The use of water level meters

A basic measurement in groundwater studies is that of water levels in wells. The measurement of the groundwater level in a well is frequently conducted in conjunction with groundwater sampling to determine the "free" water surface. Surface measurements can be used to establish groundwater direction and gradients. Groundwater level and well depth measurements are needed to determine the volume of water or drawdown in the well casing for proper purging.

Electric tapes are mounted on a hand-cranked or powered supply reel that contains the batteries and "indicator" electronics for signaling when the circuit is closed. Gold portable water level meters are designed to provide reliable and accurate measurements of groundwater levels up to 3000 feet deep.
