Rosemount 8705 Flow Meter Repair Services
June Company’s technicians repair and calibrate the Rosemount 8705 magnetic flow tube for process engineers, water treatment operators, oil and gas producers, and pharmaceutical manufacturers. We specialize in magnetic flowmeter repair and know exactly how to diagnose and restore the 8705 when it drifts, faults, or stops reading.
About the Rosemount 8705
The Rosemount 8705 is a flanged magnetic (electromagnetic) flow tube — the sensor half of a mag meter system that pairs with a Rosemount transmitter such as the 8712 or 8732. It measures conductive fluids using Faraday’s law: the flow tube’s coils generate a magnetic field, and electrodes detect the voltage the moving fluid induces. Because it has no moving parts, most 8705 failures trace to the coils, electrodes, liner, or wiring rather than mechanical wear — which is exactly where targeted repair pays off versus full replacement.
Common Rosemount 8705 Faults We Repair
- Coil open circuit / coil failure: a frequent 8705 fault that throws coil-current and “no flow signal” errors; we test coil resistance and continuity and repair or rewind to restore the magnetic field
- Electrode fouling, coating, or shorting: causes drifting, noisy, or stuck readings; cleaned, tested, and replaced as needed to restore a stable signal
- Liner damage or wear: cracks and erosion that cause leaks or measurement error, repaired by technicians experienced with Rosemount flow tubes
- Insulation breakdown / wet calibration drift: moisture ingress and coil-to-ground faults diagnosed and corrected
- Wiring and terminal-block faults: between the 8705 and its transmitter, traced and repaired
Sensor and Transmitter — We Service Both
An 8705 problem isn’t always in the flow tube. We diagnose the full loop, so if the fault is actually in the paired 8712 or 8732 transmitter, we identify it rather than returning a “good” sensor that still won’t read. Send the tube, the transmitter, or both — we’ll tell you where the problem actually is.
Calibration and Performance Verification
After repair, your 8705 receives full magnetic flow calibration — coil-current verification, electrode-circuit testing, and flow-signal accuracy across its operating range — with results documented on a NIST-traceable calibration certificate.
