Honeywell ph gaugeUTImeterRtex


The HERMetic UTImeter Rtex is a portable liquid level gauge designed for restricted gauging of petroleum products. The sensor is calibrated once at the factory and does not require subsequent calibration. The temperature probe is a RTD element. The characteristics of the RTD are stored inside the sensor. The sensor is sending true temperature values to the electronic box, therefore, changing a sensor or a tape does not require a new calibration. The unit is used for custody transfer, inventory control measurement and free water detection on marine vessels and shore tanks. The HERMetic UTImeter Rtex has to be connected to a HERMetic vapour control valve fixed on the tank.

A restricted system exists when a marine tank vessel allows some vapours from its cargo tanks into the atmosphere under normal operating conditions.
(API MPMS 17.2 A.4.1)

Principle of installation

A gauge dedicated to your application

  • HERMetic UTImeter Rtex with 1" sensing probe, FKM gaskets for the main applications in hydrocarbons.
  • HERMetic UTImeter Gtex Visc and HERMetic UTImeter Gtex Chem Visc with 2" load on the sensing probe, recommended for operation in high viscous products or for innage measurements in hydrocarbons or in corrosive liquids. Manual detection of tank bottom.
