The Mini-NBK bypass level indicator provides many of the unique features of our standard NBK series but at a fraction of the cost. Like its predecessor, the Mini-NBK uses KOBOLD’s revolutionary ring magnet float design allowing the user full flexibility in adding roller indicators, switches and other options anywhere on the periphery of the bypass tube. The use of lighter gauge materials and a streamlined manufacturing process makes the Mini-NBK a very economical choice for low pressure level measuring applications.
