Metalex Paddlewheel Flow Meter | Signet 525

Metalex Paddlewheel Flow Meter  – Overview

This stainless steel insertion paddlewheel is a highly reliable sensor suitable for use at extreme pressures and temperatures. The tungsten carbide shaft and carbon fibre reinforced PTFE bearing provide excellent wear resistance for extended service. A comprehensive fitting program allows installation in steel lines with the mini-block for small diameters, and either the mini-tap or saddle for pipes up to DN300 (12 in.). The self-generating output signal allows use with the battery-operated flow totalizer 8150.
