FLOW METER RQ-30 STAINLESS STEEL

NON-CONTACT DISCHARGE MEASUREMENT FOR OPEN WASTEWATER CHANNELS

With the RQ-30 Niro – same as with the RQ-30 – a continuous measurement of the discharge of open rivers and channels is determined. A high-quality stainless steel housing allows the usage even in aggressive waters and wastewater, for example in sewage, canal systems, or industrial facilities.
