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 outside a closed pipe without cutting it 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 battery provides approximately 20 hours of continuous operation.
