Hawk Measurement Systems products

To optimize performance in each interface application under all process environments: HAWK has developed a powerful low frequency transducer to penetrate through the suspended solids and capable of measuring the sludge bed level at the bottom of a clarifier or the lightest flocculent layer. To optimize performance under all process environments in each interface application: HAWK uses one transducer with a frequency and power level that is applicable to the density of the interface and process conditions expected in the tank. Also, HAWK can guarantee performance for controlling pumps etc, rather than for monitoring purposes only.

The ORCA Sonar Bed Level transducer emits a high powered acoustic pulse, which is reflected from the interface density selected. The reflected signal is processed using specially developed software algorithms, that eliminate lighter floating densities and stratified layers, allowing measurement of RAS or BED levels. It can be calibrated to measure lighter densities like FLOC or one of the outputs could be used for a CLARITY output, similar to a basic turbidity transmitter measuring solids in suspension. By choosing the correct sonar transducer frequency, the ORCA sonar guarantees the optimized performance when measuring both light and heavy density interfaces.
