Rosemount™ 3810 Series Electronics for Liquid Ultrasonic Flow Meters
Rosemountâ„¢ 3810 Series Electronics for Liquid Ultrasonic Flow Meters
Compatible with all Rosemount 3810 Series Liquid Ultrasonic Flow Meters, next-generation Rosemount 3810 Series Electronics provide superior low-flow accuracy and linearity throughout the calibrated flow range for reliable, long-term performance.
This powerful electronics platform reduces measurement uncertainty by rapidly processing ultrasonic flow data to ensure changing flow dynamics are communicated in a matter of seconds. In addition, the streamlined electronics design has fewer parts to simplify installation and reduce overall maintenance time and costs.
