The Fuji Electric FST Ultrasonic Flow Meter is an in-line ultrasonic flow meter with three parallel measuring paths. With the latest digital signal processing technology and the calculation algorithm, it can deliver highly precise flow measurements. With no moving parts, the FST has long-term stability while requiring only minimal maintenance work. By using the advanced anti-bubble measurement technology, the interference from air bubbles is greatly eliminated. Non conductive fluid including oil, mixed liquid, purified water can be measured.
