What Is the Honeywell HERMetic UTImeter Gtex N Series?
The HERMetic UTImeter Gtex N Series is a portable electronic liquid-level gauging instrument designed for gas-tight, closed tank measurement of stored hydrocarbons and chemicals.
The instrument is connected to a compatible vapour control valve installed on the tank. The operator lowers the sensor using the graduated measuring tape and obtains measurement indications through the electronic detection system.
The system is designed to provide multiple measurement functions through one portable instrument:
Ullage measurement: Determines the distance between the tank reference point and the liquid surface.
Temperature measurement: Provides liquid temperature readings through the integrated RTD temperature measurement arrangement.
Oil-water interface detection: Identifies the interface between oil and water.
Innage or reference-height measurement: Supports measurement procedures requiring reference-height information.
These functions make the Gtex N Series suitable for marine cargo measurement and tank inventory operations.
Gas-Tight Closed Gauging for Hydrocarbon and Chemical Cargo Tanks
Closed gauging is important when measuring cargo in tanks containing volatile, hazardous or environmentally sensitive liquids.
The HERMetic UTImeter Gtex N Series is designed to operate through a compatible vapour lock valve, allowing measurement without routinely opening the tank directly to the atmosphere.
The closed gauging arrangement helps:
Reduce exposure to cargo vapours during measurement.
Maintain the integrity of closed tank systems.
Minimise unnecessary vapour release.
Support cargo measurement in hazardous tank environments.
Assist with cargo inspection and inventory verification.
The instrument is intended for compatible closed gauging installations. The tank valve, storage tube, quick connection and instrument configuration must be correctly selected for the vessel.
Three Main Measurement Functions in One Portable UTImeter
1. Ullage Measurement and Liquid-Level Detection
Ullage is the distance between the tank’s reference point and the surface of the liquid cargo.
The UTImeter uses its graduated tape and electronic sensor to identify the liquid surface. The measurement is read from the tape through the instrument’s viewing window.
Ullage measurement is used for:
Cargo quantity calculations.
Tank inventory control.
Loading and discharge monitoring.
Cargo inspection.
Verification of automatic tank gauging systems.
2. Temperature Verification Using an RTD Sensor
Cargo temperature is an important measurement parameter in petroleum and chemical tank operations.
The Gtex N Series incorporates an RTD temperature measurement element within the sensor arrangement. The temperature information is transferred to the electronic package for display.
The instrument supports selectable temperature units in Celsius or Fahrenheit. Temperature measurement resolution is selectable between 0.01° and 0.1°, according to the published specifications.
3. Oil-Water Interface Detection
Oil-water interface measurement is used to identify the boundary between the liquid cargo and free water at the bottom of a tank.
The electronic detection system provides different audible indications as the sensor moves through the tank atmosphere, contacts the oil surface and reaches the water interface.
Honeywell HERMetic UTImeter Gtex N Series – Sensor Detection Principle
The Gtex N Series uses an electronic sensing arrangement to identify the transition between the tank atmosphere, liquid cargo and water interface.
According to the Honeywell brochure, the audible indication operates as follows:
Sensor in air: Periodic beep approximately every two seconds.
Sensor contacts oil: Continuous audible indication.
Sensor contacts water: Periodic beep approximately every 0.5 seconds.
These different indications help the operator identify the measurement point during ullage and interface gauging.
The instrument also provides visible indication, with audible and visible indication selectable according to the published technical specifications.
ULTRA Sensor Technology – Factory Calibration and Replacement
The Honeywell documentation describes the ULTRA sensor as factory calibrated, with no subsequent calibration or sensitivity adjustment required.
The temperature probe is an RTD element whose characteristics are stored within the sensor. The sensor communicates the temperature information to the electronic package.
An important advantage of this arrangement is that replacing the sensor or measuring tape does not require a new instrument calibration, according to Honeywell’s product information.
This design supports maintenance and replacement operations while helping maintain measurement performance.

HERMetic UTImeter Gtex N Series – Standard, Chemical and Visc Configurations
The Gtex N Series is offered in different configurations to suit cargo compatibility, chemical resistance, connection requirements and measurement conditions.
Standard Version – Hydrocarbon and Petroleum Applications
The standard version is intended for non-corrosive liquid applications, including suitable crude oil and petroleum products.
It uses a 1-inch sensing probe arrangement with FKM gaskets for the stated hydrocarbon applications.
Typical applications include:
Crude oil.
Petroleum products.
Suitable light chemicals, subject to compatibility confirmation.
Marine cargo tank measurement.
Chemical IIB Version
The Chemical IIB configuration is designed for applications involving non-corrosive and corrosive liquids, subject to the manufacturer’s compatibility guidance.
This version uses a 1-inch sensing probe arrangement with FFKM gaskets and a tape connector specified for chemical applications.
Chemical IIC Version
The Chemical IIC configuration is intended for use with non-corrosive and highly corrosive liquids where the selected equipment materials are suitable for the cargo.
It is important to confirm the exact chemical, concentration, temperature and operating conditions before selecting this version.
Visc Version – High-Viscosity Cargo Measurement
The Gtex N Series Visc configuration uses an additional load on the sensing probe.
Honeywell recommends this arrangement for high-viscosity products and for applications requiring innage measurement.
A Chemical Visc configuration is also available for suitable corrosive cargo applications.
The correct Visc model and connection arrangement should be confirmed against the vessel’s installed valve and intended cargo.
High-Pressure, Long-Range and Extra-Long-Range Gtex N Series Models
The Honeywell model-selection information identifies several configurations with different measuring tape lengths and maximum tank pressure ratings.
