Sonar Transducer from Hawk Measurement
August 13, 2008
Orca sonar transducers from Hawk Measurement, Middleton, MA, provide improved sensing of interface levels in clarifiers and thickeners used in municipal water and wastewater plants. Each transducer includes 3–7 sonar crystals mounted in a single head; each sonar array produces a concentrated sonar beam for greater emitted power and more returned signals. The company's Orca sonar interface products can be used to locate and track layers of differing density within a process tank, allowing you to control flocculent dosing, control settling time, and control the density of clarifying beds.
