Ultrasonic transit-time flow meter BBUFM-P

volumefor waterfor wastewater

Product Overview
BBUFM-P is a portable clamp-on ultrasonic liquid flow meter designed for field testing, inspection and temporary flow verification. Using the transit-time principle, clamp-on transducers are mounted externally on an integrated alignment rail. No pipe cutting, process shutdown or contact with the liquid is required.

Key Features

• Portable field kit for inspection and temporary measurements
• Non-invasive clamp-on installation with no pressure drop or leakage risk
• Rechargeable battery for approximately 16 hours of operation
• Color TFT display and numeric keypad for easy setup
• Integrated transducer alignment rail for consistent positioning
• 4–20 mA analog output for integration with measurement systems

Typical Applications

• Pipeline inspection and on-site flow verification
• Field comparison of installed flow meters
• Temporary measurement on industrial process lines
• Water supply, wastewater and irrigation systems
• HVAC and energy-system water-flow testing

Standard Package

• Portable ultrasonic flow-meter transmitter
