Honeywell Enraf Tanksystem HERMetic UTImeter Gtex performing ullage, temperature, and oil water interface measurement on board a tanker.

The HERMetic UTImeter Gtex from Honeywell Enraf Tanksystem is a reliable, portable Ullage Temperature Interface (UTI) instrument engineered for safe and accurate manual tank sounding on tanker vessels. Designed for closed gauging, this device lets you measure ullage level, liquid temperature, and oil‑water interface in a single operation critical for cargo control, custody transfer, and pollution prevention during marine operations.

Built to meet international standards and withstand demanding shipboard conditions, the UTImeter Gtex delivers precise readings with high repeatability thanks to its advanced electronic detection and RTD temperature sensor technology. The device’s rugged construction supports operation in hazardous zones, with approvals including ATEX and IECEx.

Key features include:
Accurate ullage detection with ±2 mm precision and ±1.5 mm tape accuracy over 30 m.
Continuous temperature measurement with ±0.1°C accuracy.
Optional oil‑water interface detection for boundary identification.
Versions available for hydrocarbons, corrosive liquids, and high‑viscosity products.
Factory calibration stored in sensor memory replacements don’t require new calibration.

Maritime regulations such as IMO SIRE 2.0 emphasize that portable UTI equipment must be serviced and calibrated in accordance with manufacturer’s recommendations and carry valid calibration certificates, with calibration intervals generally not exceeding 30 months to ensure compliance and reliability.
