The UTI detector is a portable liquid level gauge that is commonly used in the shipping industry to measure the amount of hydrocarbons and chemicals in a ship's tank. This device includes a sensor probe, measurement tape, display unit, and winding drum. Its primary purpose is to determine the temperature and oil-water interface on tankers by attaching the sensor probe to the measurement tape, which can vary in length from 15m to 40m. Manufacturers offer a temperature range between -40°C and 110°C. All UTI meters have earth grounding capabilities for safety purposes.
Note: It is very important that the Ullage Temperature Interface system is grounded to the tank before the probe is introduced into the tank and remains grounded until after complete withdrawal from the tank.
How does Ullage Temperature Interface (UTI) work?
In the following paragraphs, we will introduce how the ullage, temperature and oil-water interface are detected onboard:
The ullage detector of the UTI integrates two elements (1) electronic circuits and (2) two piezoceramic plates. When the sensor head reaches the oil or petroleum, an ultrasonic sound is emitted. The receiver processes and sends this sound to the instrument unit that emits a continuous beep sound.
The sensing component of the UTI detector is a Platinum Resistance Temperature Detector (RTD). This element is situated in the temperature electrode that is filled with a heat transfer compound paste to hasten the latency. After digitizing the RTD element signal, the micro-controller in the sensor probe corrects and compensates for any errors. The RTD element's attributes are saved in the sensor memory and are exclusively for that sensor, so a new calibration is not required when replacing the sensor. The micro-controller sends the data to the Display Unit that can be read by the technician.
The operating principle for oil-water interface level detection of the UTI detector involves measuring conductivity between an active electrode and a grounded electrode. When the liquid measured is conductive (e.g., water), the ullage sensor detects its existence. Afterwards, the conductivity electrodes and their related electronic circuits modify the coded signal generating an intermittent beep sound.
UTI meters can be either open or closed types, with the latter having a gas-tight body to prevent hazardous gases from escaping the measurement tank.
UTI (Ullage, Temperature, Interface) is an ultrasonic measure that integrates 3 functions in 1: Measuring Ullage in the tank, Temperature temperature and oil/water interface. Combining the first 3 letters of 3 features should be called UTI. The device is used mainly on oil vessels, chemical vessels and general liquid cargo tank depots.
There are not many UTI manufacturers for oil/chemical vessels, it is relatively specific and picky customers. Famous companies include MMC, HERMetic (Tanksystems), Tanktech, Marsen, Rongde.
ULLAGE TEMPERATURE INTERFACE DETECTOR is necessary for cargo tanker and it is designed for measuring the ullage level, the oil-water interface level, the temperature sampling the cargo.
