Overview
BF-3000B is an ultrasonic biogas flowmeter combining differential pressure and transit-time measurement in a bypass line, inferring main-line flow while avoiding condensation, corrosion and high-CO2 effects. Stainless construction, maintenance without disturbing the main pipe and a battery life over five years keep costs low.
Key Features
- Combination of the pressure differential and ultrasonic transit time differential principle, higher precision & longer lifetime.
- Measurement in bypass line, eliminate effect from high concentration CO2 and enhance signal quality in big diameter duct application
- Reduce the interference of flow field distribution uniformity factors.
- Eliminate the corrosion problem caused by water condensate.
- Stainless Steel design with stronger corrosion resistance.
- Low maintenance cost, no effect on main pipeline when installation and maintenance.
- Low power consumption, battery can be used for more than 5 years.
