New Low-Cost Water Radar

The VEGAPULS WL 61 level sensor from Vega (Germany) is primarily for water and sewage level measurement. Radar technology offers considerable advantages over ultrasonic devices; measurement is independent of temperature, high winds, fog or rain. New generation, high sensitivity radar electronics ensure security of measurement, even under turbulent, challenging surface conditions.  A radar sensor offers higher accuracy - where in open channel flow, for example, the sun shining on ultrasonic transducers can create large temperature errors -  especially when measured data is factored through flow equations. The focused radar signal means it can be deployed into crowded pumping chambers and the sealed cable and robust housing provide a high protection rating of IP 66/68 (1 bar). The variety of mounting options easily mechanically integrate into existing applications, and units can directly connect to existing field-bus systems or loop-powered from a signal conditioning instrument for pump control. Integrated sensor linearization curves can be programmed in using free FDT/DTM software, allowing direct output of flow rate in open channels. The new VEGAPULS WL 61 was conceived and developed to offer a real alternative to ‘ultrasonics’  in the water industry, both technically and commercially.
