FS-9XMicro-flow Ultrasonic Flow Meter

Selecting a low-flow liquid meter requires matching sensor technology with fluid physical properties and piping constraints. For clean water-based fluids, the FS-910 inline ultrasonic meter offers non-contact measurement down to 120 ml/min. For highly viscous fluids such as syrup or fuel oils, the FP-210 gear meter provides high repeatability across 0.3 to 20000 L/h. Conductive liquids can utilize the FS-510 electromagnetic flowmeter featuring a PEEK lining and 316L electrodes up to 6.3 MPa. However, flow performance varies under extreme process conditions, so this must be confirmed for the selected configuration. To receive a precise recommendation, please provide your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output to our technical engineering team.

The FS-9X micro-flow ultrasonic flow meter features a non-invasive clamp-on design with hand-tightened screws, eliminating fluid contact, contamination risks, and pressure drop. Designed for small plastic tubing with outer diameters between 6mm and 12.7mm (OD 6 to OD 12.7), it measures liquid velocities from 0.1 m/s to 5.0 m/s with +/-2.0% accuracy and 50 ms response time. The unit displays instantaneous flow, velocity, and daily/yearly totalized values on a 2.4-inch IPS LCD screen, offering 4-20mA and RS485 Modbus RTU communications. Because plastic tube wall thickness and material elasticity influence sound transmission, tube material compatibility must be confirmed for the selected configuration. Share your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output with our team.

Clamp-on ultrasonic flow meters represent a non-invasive flow measurement solution. Because transducers clamp directly onto the outer wall of plastic or metal piping (such as FS-930, FS-950, or FS-9X), no internal components restrict fluid motion. This eliminates pressure loss across the meter, reducing pump energy requirements. Furthermore, because no wetted seals or internal sensors contact the liquid, process fluids remain completely free from cross-contamination, leaks, or bio-film accumulation. This non-contact design allows installation and servicing without interrupting active production. Acoustic signal coupling through multi-layer or insulated pipes must be confirmed for the selected configuration. Send your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output for evaluation.

Biopharmaceutical fermentation demands sterile, highly repeatable process instrumentation. For pH tracking, the AS3250 electrode withstands repeated 130°C SIP cycles with its 400 Mohm glass membrane and silver ion trap. For dissolved oxygen, the AS6860i optical sensor provides zero-polarization, zero-electrolyte measurement with USP Class VI EPDM seals and 316L polished surfaces (Ra <= 0.4 um). Non-contact liquid flow monitoring on flexible single-use tubing is handled by the FS-9X clamp-on ultrasonic meter (OD 6 to 12.7mm). Transmitter integration is simplified using B Series DIN Rail units. Clean-in-place chemical resistance must be confirmed for the selected configuration. Please supply your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output for a tailored bioprocess package.
