System description

The EMx40 level radar transmitters, T901-P temperature/pressure transmitters and LOG3840 deck digital indicator are parts of the EMx40 system, dedicated to monitor the tankers liquid cargo parameters such as level, temperature and pressure, as well as all associated measurements. They are installed in hazardous area.

The EMx40 radar level transmitters measure the liquid level inside the tank and transmit the information to the TA3840C communication unit by means of the TA3840S safety unit located in cargo control room. Each EMx40 radar is fitted with entries for temperature/pressure transmitter and the EM940 radar with additional analog transmitters.

The T901-P temperature / pressure transmitters measure the liquid cargo temperature and the inert gas pressure. Each T901-P transmitter is directly connected to EMx40 radar.

The LOG3840 deck digital indicator displays locally the level, temperatures, pressure measured by transmitters. It is powered by the TA3840S safety unit and communicates on the same bus than the radar.

General synopsis

The general synopsis of the system is shown on the previous page.

Radar level transmitter

The EMx40 radar is a stand-alone radar type level transmitter using a frequency modulated continuous wave (FMCW), electromagnetic signal to measure distance between its antenna and cargo tank content surface (ullage).

The EMx40 radar performs the following functions:

● Measures the liquid level (in mm) by processing the microwave signal thanks to its dedicated signal processor,

● Concentrates the measurements of:

- Liquid temperature coming from three sensors at different levels (top, middle and bottom of the tank),

- IG pressure coming from a pressure sensor,

- Up to two other analog measurements for EM940 radar

● Transmits the data to the cargo control room.

The EMx40 radar is fastened on the deck, on top of a socket by means of 4 or 6 bolts. No part of the radar is in actual contact with the liquid in the tank and the antenna is the only part exposed to the tank atmosphere.

The EMx40 radar comprises:

● A 316L stainless steel circular housing protecting the electronics,

● A FLAT-T technology antenna covered and protected against tank atmosphere by PTFE radome,

● A terminal box fitted with three packing-glands for electrical cables.

T901-P temperature/pressure transmitter

The T901-P temperature/pressure transmitter is located on deck, on top of each tank, on a socket.

The T901-P temperature/pressure transmitter measures:

● The liquid temperature in the cargo tank at up to three different levels (high, middle and low),

● The inert gas pressure inside the cargo tank.

The T901-P temperature/pressure transmitter comprises:

● 1 to 3 platinium RTD 100 at 0 °C, located in a protecting tube immersed in the cargo tank,

● An absolute or gauge pressure sensor and its associated electronics, located inside transmitter housing,

● A 316L stainless steel housing protecting the electronics, fitted with one packing-gland for electrical cable,

● A cover for access to the terminal block.

There are several types of T901-P transmitter:

● An universal model:

- With 1, 2 or 3 temperature sensor(s),

- With or without pressure transmitter,

● A model for installation on pump body, with 1, 2 or 3 temperature sensor(s).

● A model for Inert Gas pressure measurement, or other pressure for EM940

LOG3840 deck digital indicator

The LOG3840 deck indicator is located on deck. It operates in spy mode, reading and displaying data picked up on the communication line between the EMx40 radar (connected to the T901-P transmitter) and the TA3840S safety unit.

The LOG3840 deck indicator calculates and displays on the LCD screen:

● The liquid level in the cargo tank expressed in innage or ullage,

● The liquid spot or average temperature in °C or °F,

● The inert gas pressure in mbar.

3. LOG3840 DECK DIGITAL INDICATOR OPERATION

Starting up

This module is powered as soon as the TA3840S safety unit is on. The screen lights on and data are displayed, depending on the operating parameters set up.

LCD display arrangement

The LCD screen indicates the following information:

● 3 main lines for the data,

● 4 spots for five messages (data and communication errors).

Line 1 5 digits + decimal dot for level display

Spot 1 communication working (RM) or communication error (CE)

Line 2 4 digits + decimal dot for temperature display

Spot 2 level data error (LE)

Line 3

4 digits + decimal dot adjustable for pressure display Note: if a decimal dot is set up, the mbar unit disappears.

Spot 3 temperature data error (TE)

Spot 4 pressure data error (PE)

The deck digital indicator includes a component (A) activated by an external magnet through the window, for selection of the data displayed on the second line.

Operation

The display mode for level (ullage or innage), the unit used for level and temperature, and the pressure decimal dot are set up by means of the utility software.

Only the different temperatures display, step by step, is possible.

● Touch the switch (A) with the magnet to display successively the average temperature and the temperature measured by each sensor, according to the data availability depending to the current T901-P transmitter type.



22

Default step: average temperature,

Step 2: upper temperature display,

Step 3: middle temperature display,

Step 4: lower temperature display.

Back to default step.

The average temperature is calculated according to the temperature recorded by each sensor immersed in the liquid cargo. When the liquid level is under the lowest sensor, its temperature is displayed.
