The Signet 525 Metalex impeller-flow sensor combines stainless steel construction with insert-impeller wheel technology. The result is an extremely reliable sensor that is suitable for use at extreme pressures and temperatures. The Tungsten Carbide axle and the carbon fiber reinforced bearing offer excellent wear resistance for long-term maintenance. An extensive assembly program enables installation in steel pipes with the mini-block for small diameters, and either the mini-crane or the saddle for pipes up to DN300 (12 in.). The self-generating signal output enables use with a battery-operated flow monitor (8150).
