Ultrasonic transit-time flow meter BBUFM-H

volumefor waterfor wastewater

Product Overview
The BBUFM-H is a handheld clamp-on ultrasonic liquid flow meter designed for field inspection, commissioning and temporary measurements. Clamp-on transducers attach externally to the pipe (magnetic or bracket mounting) to measure flow without interrupting the process or introducing pressure loss.

Key Features

• Portable handheld design for rapid field and commissioning checks
• Non-intrusive clamp-on installation; no pipeline shutdown or cutting required
• Measurement accuracy ±1% and high repeatability
• Covers pipe sizes from DN15 to DN6000 depending on transducer
• Available standard and high-temperature transducers; transducer protection IP67
• Backlit 4 × 16-character LCD for on-site readout
• Built-in data logger (>2,000 records) and isolated RS232 communication
• Battery operation using three 1.2 V AAA Ni–MH cells; >12 hours continuous use
