FS-910Inline 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.

Choosing between inline and clamp-on ultrasonic meters depends on maintenance access and installation preferences. Clamp-on flow meters like the FS-930 attach to the pipe exterior using magnetic clamps, eliminating process shut-downs, leak risks, and fluid contamination. Inline models like the FS-910 utilize pre-calibrated UPVC pipe segments, delivering 20ps time resolution and 1.0% accuracy for pipe outer diameters from 5mm to 12mm. While inline units provide defined flow geometry for micro-flows, clamp-on sensors handle lines up to DN100 or higher without pressure loss. Chemical resistance for inline wetted parts depends on concentration and temperature, so this must be confirmed for the selected configuration. Send your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output to verify compatibility.

Fluid viscosity significantly impacts flow sensor mechanics and sound propagation. Gear flow meters like the FP-210 operate on positive displacement principles, where rotating gears maintain reading accuracy of +/-0.5% in viscous media such as syrups, honey, and asphalt up to 2x10^6 mm2/s. Conversely, transit-time ultrasonic meters like the FS-910 require ultrasonic wave transmission through the fluid, operating reliably when liquid viscosity remains below 300 cSt. Highly viscous fluids can attenuate ultrasonic signals or increase differential pressure in gear chambers. Because extreme viscosity shifts alter calibration curves, performance must be confirmed for the selected configuration.

The FS-910 inline ultrasonic flow meter is specifically engineered for precise micro-flow detection in liquid dispensing, laboratory reagents, and chemical dosing. Powered by an advanced measurement chip with 20ps time resolution, it delivers 50 ms response times and +/-1.0% accuracy across flow velocities from 0.1 m/s to 5.0 m/s. Three standard pipe outer diameter models are offered: -5 (120-6000 ml/min), -B (300-15000 ml/min), and -12 (680-34000 ml/min). Wetted parts are constructed from UPVC rated for 0.3 MPa pressure. Display features include a 4-direction rotatable 2.4-inch IPS LCD. Fluid chemical compatibility with UPVC must be confirmed for the selected configuration. Provide your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output for confirmation.

Transit-time ultrasonic measurement relies on high-frequency sound waves propagating across moving liquid streams. All standard CurioSens transit-time flow meters—including the FS-910 inline micro-flow meter, FS-920 industrial union meter, FS-930/FS-950 clamp-on series, and FS-9X tubing sensor—are specified for applicable liquid viscosities below 300 cSt (mm2/s). Liquids with higher viscosities, such as heavy oils or concentrated polymers, absorb sound energy and alter laminar velocity profiles, potentially reducing signal-to-noise ratios. For viscous liquids above 300 cSt, positive displacement gear meters like the FP-210 should be evaluated instead. Signal penetration in non-Newtonian liquids must be confirmed for the selected configuration. Share your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output with our application engineers.

Transit-time ultrasonic meters (such as the FS-910, FS-920, and FS-930) calculate flow by measuring time differences between upstream and downstream acoustic pulses. For accurate signal transmission, the liquid medium must be homogeneous. CurioSens transit-time meters tolerate minor particulate impurities or bubbles up to <= 4% concentration. Higher concentrations of entrained air, heavy slurries, or undissolved solids scatter acoustic beams, leading to degraded signal quality or temporary measurement drops. In aerated or heavy slurry applications, alternative technologies like Doppler ultrasonic or electromagnetic meters (FS-510) should be specified. Exact particle size and concentration thresholds must be confirmed for the selected configuration. Provide your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output for assistance.

Semiconductor wet bench processing and chemical delivery systems require ultra-clean, corrosion-resistant measurement tools. The FS-910 inline ultrasonic flow meter provides non-contact micro-flow measurement in UPVC pipe lines down to 120 ml/min without moving parts. For ultrapure water (UPW) loop monitoring, the AS7000 2-pole stainless steel conductivity sensor provides +/-1% accuracy down to 0.01 uS/cm resolution with sanitary Tri-Clamp connections. For bulk conductive chemical lines, the FS-510 electromagnetic flow meter features a PEEK lining and 316L electrodes rated up to 6.3 MPa. High-purity PFA chemical compatibility must be confirmed for the selected configuration. Share your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output for sizing.

Medical and laboratory equipment OEMs require compact, reliable instrumentation with standardized digital communications. For gas delivery in analyzers or bioreactor sparging, the FS-600 MEMS thermal gas flow meter provides 1:100 turndown and fast response (50-1000 ms) in a compact block with a rotatable screen. Liquid reagent dosing uses the FS-910 inline ultrasonic meter for micro-flows down to 120 ml/min. Analytical sensor integration is simplified by the B Series DIN Rail transmitter, which offers 24VDC power, isolated Modbus RTU, and compact mounting inside analyzer cabinets. Custom OEM mounting interfaces must be confirmed for the selected configuration.
