The RBBF Ultrasonic Flow Meter is a fixed-mount, low cost transit-time ultrasonic flow meter with clamp-on transducers for non-invasive liquid flow rate measurement. Our microprocessor-based, user friendly field programmable creates no interruption of the process flow and has low installation costs.
This versatile series of flow meters is available in a variety of configurations. Available transducer types include clamp-on, in-line, and insertion. Wall-mount, panel-mount, pipe-mounted and compact din-rail mounted display types are also offered. Additional available features include pulse, 0-20mA & 4-20mA outputs, RS-232 communication, user-selectable engineering units, and a data logger function.
