Overview
The Tianyan TY-X3M Clamp-on Ultrasonic Flow Meter is an industrial-grade, non-invasive transit-time ultrasonic flow measurement system engineered for high-reliability liquid flow monitoring in process-critical environments. Unlike inline or insertion-type meters, the TY-X3M employs dual transducers mounted externally on the pipe wall—eliminating pressure drop, process interruption, and contamination risk. Its measurement principle relies on precise time-of-flight differential analysis between upstream and downstream ultrasonic pulses, enabling accurate volumetric flow calculation independent of fluid conductivity, density, or chemical composition—provided the liquid exhibits sufficient acoustic transmission (sound speed > 600 m/s) and low particulate/air content (<4% by volume). Designed for continuous operation in semiconductor fab utilities, pharmaceutical water systems, food & beverage CIP lines, and chemical dosing loops, the TY-X3M delivers traceable, repeatable flow data compliant with foundational requirements of ISO 9001 process validation and FDA 21 CFR Part 11–aligned data integrity frameworks when integrated with audit-trail-capable SCADA or MES platforms.
Key Features
- True Non-Intrusive Architecture: Zero process penetration—no welding, cutting, or valve isolation required. Installation completed in under 60 seconds per sensor pair using integrated magnetic alignment and captive-thread clamping hardware.
- High-Resolution Timing Core: Proprietary ASIC with 20-ps time resolution ensures stable velocity detection even at low-flow conditions (≥0.3 m/s), minimizing signal drift under turbulent or laminar flow regimes.
- Universal Pipe Material Support: Adaptive signal compensation algorithms auto-adjust for acoustic impedance mismatches across carbon steel, stainless steel, copper, PVC, PP, HDPE, and lined pipes—no manual calibration per material.
- Industrial-Grade Human Interface: 1.54″ 240×240 IPS LCD with four-axis rotational mounting enables legible readings in confined spaces or low-illumination environments (e.g., utility tunnels, cleanroom subfloors).
- Multi-Protocol Digital Integration: Standard RS485 Modbus RTU interface supports seamless integration into DCS, PLC, and IIoT edge gateways; optional pulse output and programmable 4–20 mA analog output conform to IEC 61000-6-2 EMC standards.
- Long-Term Data Integrity: Onboard 7-digit accumulator retains 10 years of daily/monthly/yearly cumulative totals with RTC backup (CR1220 battery), supporting batch reconciliation and regulatory trend analysis.
Sample Compatibility & Compliance
The TY-X3M is validated for single-phase, homogeneous liquids with sound attenuation ≤ 0.5 dB/m at 1 MHz—including purified water (PW), water-for-injection (WFI), deionized water, ethanol, isopropanol, dilute acids (e.g., ≤10% H₂SO₄), caustic solutions (e.g., ≤5% NaOH), organic solvents (e.g., acetone, THF), and food-grade syrups (viscosity <300 cSt). It is not suitable for slurries, aerated liquids, or fluids containing suspended solids >4% v/v. The device meets IP54 ingress protection as standard (IP65 available with optional enclosure), and its non-wetted design complies with USP <1058> analytical instrument qualification guidelines for Category B instruments. While not certified to ATEX or IECEx, it is rated for use in non-hazardous Zone 2/Class I Div 2 environments when installed per NEC Article 501.
Software & Data Management
No proprietary PC software is required for commissioning—the TY-X3M features an intuitive hierarchical menu system navigated via four tactile buttons. All configuration parameters—including pipe material, wall thickness, fluid type, unit selection, damping factor, and alarm thresholds—are accessible without numeric code memorization. Language switching (Simplified Chinese / Traditional Chinese / English) is instantaneous. For centralized deployment, the Modbus RTU register map exposes real-time flow rate, velocity, totalizer values, signal quality index (SQI), and diagnostic flags (e.g., low SNR, transducer detachment alert). When connected to a historian or LIMS, timestamped data streams support ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) under GxP-regulated workflows.

FAQ
Does the TY-X3M require pipe material calibration for each installation?
No. Its adaptive signal processing automatically compensates for acoustic impedance differences across metallic and thermoplastic pipes using built-in material libraries and real-time echo amplitude analysis.
Can it measure flow in insulated or painted pipes?
Yes—provided insulation thickness does not exceed 25 mm and paint layers are non-foamed and ≤0.5 mm thick. Acoustic coupling gel must be applied directly to bare pipe surface beneath insulation termination points.
Is the 4–20 mA output intrinsically safe?
The standard 24 VDC-powered output is non-IS. For hazardous areas, external Zener barriers compliant with IEC 60079-11 must be used in series.
What is the minimum straight-pipe requirement upstream/downstream?
Zero—clamping eliminates dependence on flow profile development. However, optimal accuracy is achieved with ≥10D upstream and ≥5D downstream of disturbances (e.g., elbows, valves); field validation recommended per ISO 5167 Annex F.
How is measurement traceability maintained during power loss?
The CR1220 RTC battery preserves date/time stamp and accumulated totals for ≥3 years. All flow events retain synchronized timestamps upon power restoration, ensuring continuity for batch records and audit trails.
