Description
Product Introduction
Engineers face significant operational challenges when tracking liquid flow rates in hazardous, high-pressure, or highly corrosive piping systems without stopping process lines. The Panametrics XMT868i-1-11-00-0315-0 provides a reliable solution by processing transit-time ultrasonic signals to measure liquid velocity without causing pressure drops or fouling moving parts.
Designed for Class I, Division 1 hazardous areas, this transmitter interfaces with either external clamp-on transducers or wetted spool pieces. Installing a factory-tested spare unit restores accurate volumetric flow monitoring and 4–20 mA feedback loop signals to host PLC and DCS control systems during unexpected field failures.
Key Selling Points & Differentiators
- Non-intrusive transit-time measurement eliminates pressure drops, line clogs, and mechanical wear associated with orifice plates or turbine meters.
- Every surplus unit undergoes a comprehensive 5-point quality verification process including 500 V megger isolation testing and a 24-hour continuous live bench test.
- Microprocessor-controlled digital signal processing (DSP) automatically filters out pipe vibration and hydraulic turbulence noise.
- Not recommended for slurry or heavy aerated liquid applications where entrained solids/bubbles exceed 10% by volume.
- Fully compliant with API and international industrial standards for explosion-proof fluid metering enclosures.
Standard Quality Control Procedure
To guarantee field operational readiness upon arrival, every unit completes a structured 5-step engineering verification protocol:
- Incoming Inspection: Verification of physical documentation, visual inspection of explosion-proof flame-path cover threads, terminal board screw condition, and serial/part number cross-referencing.
- Live Functional Test: Mounting on a test bench for power-up verification, acoustic pulse excitation signal testing, simulated transit-time calculation across full velocity sweeps, and 24-hour continuous burn-in testing with thermal monitoring. Detailed test reports are available upon request.
- Electrical Parameter Tests: Insulation resistance evaluation using a 500 V megger (>10 MΩ target) between AC line terminals and chassis ground, alongside output current loop linearity checks.
- Firmware / Configuration Verification: Digital extraction and recording of internal DSP firmware builds, default parameter settings, and communication protocol configurations.
- Final QC + Packaging: Engineering sign-off, sealing conduit hubs with protective plugs, ESD wrapping, heavy-duty foam cushioning, and attachment of a dated “QC Passed” label. Passed the above checks; verified functional at time of test.
