The RBFM-F Fixed type clamp-on Ultrasonic Flow Meter is a a non-intrusive flow measurement that measures volumetric flow, low cost transit-time ultrasonic flow meter with clamp-on(strap-on) transducers for non-invasive liquid flow rate measurement.
The RBFM-F Fixed type Clamp-on Type Ultrasonic Flow Meter Advantage:
- Cost-effective and easy installation
- Transducers for wide pipe sizes ranging from15 to 6000 mm (½" to 240").
- Wide range velocities of ±0.1~ ± 12m/s (0.03 ~ ± 105 feet/sec.)
- High accuracy of ± 1% of reading
- Suitable for a wide variety of liquid types
- Fast response time - less than 1 second.
- 2 line LCD display with flow rate, totalizer & signal condition.
- 0-20mA & 4-20mA outputs, RS-232 communication, user-selectable engineering units, and a data logger function
- Clamp-on transducers feature integral magnet for installation
- Data logger function includes date, totalizer, & signal condition diagnostic
