HONEYWELL ENRAF Equipment We Repair — By Category
HONEYWELL ENRAF Product Lines We Repair
Our engineers are trained on the full HONEYWELL ENRAF product range. Below are the major product families we service.
Atlas Insite Tank Gauging System
Multi-product tank level measurement and inventory management platform using radar and servo gauge technology. Common faults include gauge arm friction, servo motor stalling, and communication protocol failures between field instruments and central monitoring units.
FlexyRack Level Measurement
Flexible racking systems for precise liquid level detection in storage tanks with secondary containment compatibility. Repairs address tape fraying, pulley alignment issues, and weight sensor calibration drift common in high-temperature or corrosive environments.
RadarWeighing Density Measurement
Radar-based density and interface detection for multi-product tank environments. Typical failures include antenna fouling, frequency drift, and signal attenuation in metallic tank structures common in Indian oil terminals.
Enraf TM1100 Radar Gauge
Non-contact radar measurement for hazardous area tank gauging in refineries and chemical storage. Repairs cover magnetron tube replacement, waveguide corrosion, and SDU (signal distribution unit) power supply failures.
Enraf Electronic Gauges
Servo-driven mechanical gauges with electronic position output for custody transfer and inventory management. Common repair items include stepper motor failures, encoder drift, and intrinsically safe barrier malfunction.

Common HONEYWELL ENRAF Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HONEYWELL ENRAF equipment arriving at our workshop.
- ✓Atlas Insite communication loss to gauge instruments — Honeywell Enraf Atlas systems communicate via proprietary protocols (MODBUS or SDU protocols) over RS-485 or Ethernet. Corrosion of terminal blocks in high-humidity terminal environments, loose shielded cable connections, or failed repeater modules in multi-kilometer installations are primary causes.
- ✓Gauge arm servo motor stalling or jerky movement — Mechanical friction in Enraf gauge rod guides due to salt deposits, water ingress, or lubrication breakdown in coastal refineries. Stepper motor coil insulation failure or encoder signal loss prevents smooth arm positioning, triggering fault codes 1204 or 1205 on Atlas terminals.
- ✓RadarWeighing antenna signal loss or reduced accuracy — Honeywell Enraf radar antennas accumulate condensate, scale, or crude oil residue in storage tank domes, degrading signal transmission. Waveguide corrosion or magnetron tube aging (typical life 5-7 years) reduces power output below -3dB sensitivity thresholds.
- ✓Electronic gauge weight sensor drift or zero offset errors — Honeywell Enraf electronic gauge sensors experience zero shift due to thermal cycling in tanks without temperature compensation, corrosion of strain gauge bridges in wet environments, or mechanical stress from tank vibration. Offset errors exceed ±5mm range specifications.
- ✓TM1100 radar gauge display flickering or offline — Power supply failures in Honeywell Enraf TM1100 SDU (Signal Distribution Unit) caused by surge transients from tank switchyard lightning strikes, or capacitor degradation in 24VDC supply circuits. Firmware corruption can also disable display output.
- ✓Enraf tape breakage or fraying in FlexyRack systems — Invar or stainless steel measuring tape in Honeywell Enraf FlexyRack assemblies corrodes or develops micro-fractures under repeated tension cycles (typical life 8-12 years). Misalignment of pulleys or worn sprocket teeth accelerate tape wear in high-frequency measurement cycles at busy loading terminals.
