Paddlewheel Flow Sensor Signet 515 Rotor-X
Simple to install with time-honored reliable performance, Signet Model 515 Rotor-X Paddlewheel
Flow Sensors are highly repeatable, rugged sensors that offer exceptional value with little or no maintenance. The wide dynamic flow range of 0.3 to 6 m/s (1 to 20 ft/s) allows the sensor to measure liquid flow rates in full pipes and can be used in low-pressure systems. Fields of Application:
Pure Water Production Filtration Systems Chemical Production Liquid Delivery Systems Pump Protection Scrubber Systems Water Monitoring Not suitable for gases
Wide turndown ratio of 20:1 Highly repeatable output Simple, economical design Installs into pipe sizes DN15 to DN900 Self-powered/no external power required Test certificate included for -X0, -X1 Chemically-resistant materials Specification
