The Keller 46X is a high performance pressure sensor utilises a ceramic measurement cell optimised for small measurement ranges. With this in mind the PR46X is an ideal sensor solution for projects seeking high accuracy pressure data under lower water heads. The PR46X is best suited for surface water monitoring and flow monitoring in conjunction with a control structure such as a flume or weir
