SmartMeasurement’s Alsonic FX transit-time ultrasonic flow meter is a low cost, fixed-mount liquid flow rate measurement solution, with clamp on transducers for non-invasive measurement. This microprocessor-based, user-friendly, field-programmable clamp on flow meter creates no interruption of the process flow.

This versatile ultrasonic flow meter is available in a variety of configurations to meet the needs of a wide range of applications. Available transducer types include clamp on, inline, and insertion. Wall-mount, panel-mount, pipe mounted, and compact din-rail mounted display types are also available. Other optional features include pulse, 0-20 mA and 4-20 mA outputs, RS-232 communication, user-selectable engineering units, and a data logger function.
