The Sonic-Pro S3 Hybrid Ultrasonic Flowmeter from Blue-White Industries will measure flow in virtually any fluid in which sound can travel. The sound transducers are clamped to the outside of the pipe wall to measure flow in clean and dirty fluids. It is well-suited for use in applications where harsh chemicals or other abrasive fluids are being used because the meter never encounters the fluid being measured. It has a backlit LCD display with a five-button, fully configurable, tactile switch keypad interface. The security system allows for master and configuration passwords. The meter may be ordered with a T-Track Mounting System, which is designed to quickly and accurately mount the transducers utilizing built-in ruler and mounting base to ensure transducers are perfectly aligned and spaced. It comes with user-selectable Doppler or Transit Time operation; can be factory configured; and has a portable, rugged carrying case. 714-893-8529; www.blue-white.com
