NRF-1W - Flexible Cable Water Well Level Transmitter

Brand: KOBOLD Instruments, Inc

The KOBOLD NRF-1W flexible-cable water well level transmitter is a highly dependable, deep water-well level sensor, designed to measure water levels within in-ground pipes of 3/4" ID and larger. 

All wetted surfaces are PFA-clad and 316 stainless steel. The flexible, segmented weight facilitates ease of installation around slight bends in pipes. 

The microprocessor-based transmitter, which converts the capacitance change into a linear, highly accurate 4-20 mA signal, is mounted in the head mounted enclosure. Optional remote-mounted electronics are also available. 

The water-well level transmitter operates at a higher frequency than similar devices, up to 2 MHz maximum, thereby minimizing the effects of coating on the probe. 

The compact and advanced microprocessor-based design makes installation and set-up a simple task.
