ELE-808B and ELE-809 use ultrasonic measurement for liquid levels and material levels. ELE-808B combines the electronics and sensing head in an integrated unit. ELE-809 uses a separate display/controller and probe, allowing the operator interface and measurement point to be installed separately.
Built-in temperature compensation supports measurement across the specified operating temperature range. Applications include wastewater tanks, settling and aeration basins, rivers and water-resource monitoring, storage tanks, silos, hoppers and industrial process vessels. Select the range and installation arrangement for the material surface and available measuring distance.

Specify the integrated or split construction, measuring range, supply and output when selecting a unit. Allow for the 0.3-0.55m blind zone between the probe and the closest measured surface. IP66 protection and customized functions are available for applications requiring a different configuration.
ELE-700 and ELE-700-20 use aluminium alloy explosion-proof integrated housings. ELE-807 and ELE-808 configurations use integrated ABS housings. The ELE-809 family separates the probe from the display/controller. Relay options depend on the exact model.
