EF10 Flow Metering

Clamp On Ultrasonic Flow Measurement

Commercial, hospitality, institutional, research and manufacturing managers need to monitor flows across the facilities and processes they serve. Spire’s EF10 ultrasonic meter is the economical, easy to install solution for accurate flow of a wide variety of fluids. Fuel oil, coolant, or other non conductive, harsh fluids are not a problem for our non intrusive, transit time technology. Clamp on ultrasonic flow transducers install without breaking pipes or interrupting service- ready to go to work the day you receive. Utility management and billing, simplified.
