The GF Signet 525 Metalex™ paddle wheel flow sensor combines stainless steel construction with insertion paddle wheel technology. The result is a highly reliable sensor suitable for operation at extreme pressures and temperatures. The GF Signet 525 features a Tungsten Carbide shaft and a Fluoroloy B® / PTFE bearing, which provide excellent wear resistance for extended service .

The 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 any battery operated flow totalizer, including the GF Signet 8150 flow totalizer .

Applications include boiler feedwater monitoring, HVAC systems, chemical transport, heat exchangers, reverse osmosis, and cooling systems. Flow rate range is 0.5 to 6 m/s (1.6 to 20 ft/s) for pressures up to 1500 psi and temperatures up to 300°F. The 316SS body, Tungsten Carbide or SS shaft, and Fluoroloy B/PTFE bearing ensure long-term reliability in demanding applications. Not suitable for gases .
