The KOBOLD series NRF-1W cable radio frequency level transmitter is designed to measure water levels in ground pipes of 3/4” and larger. All wetted surfaces are Teflon and 316 stainless steel. The flexible segmented weight facilitates the ease of installation around slight bends in pipes. The microprocessor-based transmitter converts capacitance change into linear, highly accurate 4-20 mA signal is mounted in the enclosure, but optional remote mounted electronics are available. The NRF operates at a higher frequency than similar devices, up to 2 mHz Max., thereby minimizing the effects of coating on the probe. The compact and advanced microprocessor-based design makes installation and setup a simple task.
The NRF-1W is a highly dependable water well level sensor.
