The Signet 525 Metalex Flow Sensor offers the added strength of an all 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 Fluoroloy B® bearing provide an increased length between maintenance. 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 signal output allows use with battery operated flow monitor (8150).
