EB100, EB200
EB100, EB200 by AMOT UK HOLDINGS LIMITED. DNV TA certificate TAA000010U.
Inspector Detail
▸
Common issues
- Antenna/measuring horn fouling from cargo vapour condensation or product build-up
- Signal loss or erratic reading from a still-pipe obstruction or misalignment
- Servo/electronics fault in the transmitter head causing loss of level signal to the cargo control room
- Calibration drift between the radar reading and manual ullage/sounding
- Power supply or intrinsically-safe barrier fault causing loss of reading
- Condensation or moisture ingress into the transmitter housing affecting reliability
Inspection checklist
- Cross-check the radar level reading against a manual ullage/sounding tape at a stable condition
- Inspect the antenna/horn for cargo residue or corrosion build-up
- Check the still-pipe for obstructions, holes or misalignment affecting the signal path
- Verify transmitter housing seals and cable glands are intact for hazardous-area integrity
- Confirm high-level and overfill alarm setpoints trigger correctly during test
- Check the power supply/barrier and the communication link to the cargo control/monitoring system
- Inspect earthing/bonding of the gauge housing per hazardous area requirements
- Review calibration/zero-span records against the maker's procedure
Service intervals
| Cross-check against manual sounding | at each cargo operation, per company procedure |
| Full calibration check | annually, or per maker/class recommendation |
| Antenna/still-pipe cleaning | at drydock, or sooner if fouling is evident from reading discrepancies |
| Overfill/high-level alarm function test | before cargo operations and at periodical survey, per class and terminal requirements |
Typical wear limits
| Reading accuracy vs. manual sounding | commonly expected within a small tolerance, on the order of a few millimetres to about 1 cm depending on tank height - confirm the exact accuracy class against the DNV type-approval certificate rather than treating this as a fixed figure |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Critical spares
- Transmitter head/electronics module - confirm the exact AMOT part number with an authorised service agent, none assumed here
- Cable gland/seal kit for the hazardous-area housing
- Remote display/indicator unit in the cargo control room
- Antenna extension/horn assembly
Safety
- Installed in a hazardous cargo tank area - any repair or gland work must preserve the intrinsic safety/explosion-proof certification; do not substitute non-approved parts
- Loss of an accurate level reading during loading is an overfill risk - have a backup sounding method ready before working on the gauge
- Static/bonding continuity must be verified after any housing work
Class survey
Cargo tank level and overfill alarm systems are safety-critical under SOLAS/IBC Code requirements for tankers. Class surveys require function/accuracy verification of level gauging and of the independent high-level/overfill alarm, with the DNV type-approval certificate (TAA000010U) confirming the design meets the applicable performance standard.
