Cable water level meter 11.08.07

With the Interface meter you can quickly and easily determine light (floating) non-aqueous phase liquids (LNAPL) and dense (sinking) non-aqueous phase liquids (DNAPL) to a depth of 30 metres. The interface meter is CSA certified for class one groups C and D locations till 50 °C. Accurate, reliable, robust Determine light non-aqueous phase liquids and dense non-aqueous phase liquids Designed for rugged field use Sturdy free-standing reel with carrying handle Stable electronics with automatic circuitry testing Laser-marked flat tape; easy to decontaminate; resists strains Description This interface meter allows you to quickly and easily determine light (floating) non-aqueous phase liquids (LNAPL) and dense (sinking) non-aqueous phase liquids (DNAPL). The interface meter is very accurate, reliable and robust, making it ideal for use in the field. If the liquid is a non-conductive oil/product the light and tone signals are continuous. And if the liquid is water (conductive liquid > 50 μS/cm), the tone and light signals are intermittent. Both sensors use the same zero point, which gives an accuracy as good as 1.0 millimetre (or 1/200 foot). The high accuracy enables the sensors to detect the slightest sheen of oil on the surface of the water. Method To measure the thickness of a floating layer, lower the probe into the well until the signals activate. If there is an oil/product layer on the top of the water (LNAPL), the light and tone will be steady. Read the depth of the permanently marked tape.
