Ultrasonic flow meter BBUFM-PR

volumefor waterfor wastewater

Product Overview
The BBUFM-PR is a portable clamp-on ultrasonic liquid flow meter for field testing, commissioning, maintenance and temporary measurement. Transit-time transducers mount on the outside of a closed pipe without cutting or introducing pressure loss. A backlit display, data logger and miniature thermal printer support immediate or scheduled printing of measurement results. The built-in rechargeable Ni‑MH battery provides approximately 20 hours of continuous operation.
