It is the engineers and technicians' hope to measure the flow on the non-invasive pipeline reliably. Series SUF-300 ultrasonic flow meters providing a measuring system with unsurpassed accuracy, versatility, ease of installation and dependability. Although designed primarily for cleaner liquids, the flow meter can reliably measure liquids containing moderate amounts of suspended solids or aeration. SUF-300 is designed for long-or short-term flow measurement surveys on full-pipe liquid systems and is ideal for verifying calibration of permanently mounted flow meters of all types.
