The Signet 525 Metalex™ paddlewheel flow sensor combines stainless steel construction with insertion paddlewheel technology. The result is a highly reliable sensor resistant to extreme pressures and temperatures. The tungsten carbide shaft with carbon fiber-reinforced PTFE bearing provides excellent wear resistance for extended service.
A comprehensive fitting program allows installation in steel lines with the mini-lock for small diameters, and either the mini-tap for pipes up to DN300 (12 in). The self-generating signal output allows use with the Signet 8150 battery-operated flow monitor.
Applications include: boiler feedwater monitoring, HVAC, chemical transport, heat exchangers, reverse osmosis, cooling systems. Not suitable for gases.
