The WL900 is ideal for a variety of water and wastewater applications involving a reflective liquid that has a foaming surface, vapors, or dusty conditions beyond ultrasonic wave capabilities.
The WL900 uses a state of the art radar pulse technology, which provides accurate and reliable level measurements over a wide 10-inch to 50-foot range. The unit’s microwave sends out very short pulses, which reflect off a target and are received back by the antenna for processing.
With its single push-button calibration system, the WL900 is easy to set up and maintain. Simply aim the WL900 at your low range level set point and push the button to lock in the setting– then do the same with the high level set point. This may be done before permanent installation by aiming at a wall and using a tape measure to determine your exact range.
The unit’s rugged NEMA 4 (IP65) housing is available in either aluminum or 316L stainless steel for corrosive environments. A standard 2 inch NPT (M) process connection allows for quick and versatile installation. In addition, the unit’s polypropylene antenna rod is virtually corrosion proof.
