Installation Manual 308014EN, Edition 4 May 2013 2. Rosemount Tank Radar REX Chapter 2 Safety Safety Rosemount TankRadar REX equipment is often used in areas where flammable materials are handled and where an explosive atmosphere may be present. To protect both the plant and the personnel, precautions must be taken to ensure that this atmosphere cannot be ignited. These areas are called hazardous areas and equipment within these areas must be explosion protected.
Installation Manual Rosemount Tank Radar REX Chapter 2 Safety 2.2 308014EN, Edition 4 May 2013 Explosion Proof Explosion proof enclosures can be used when an explosion can be allowed inside the enclosure as long as it does not spread to the outside. The enclosure must be strong enough to withstand the pressure and must have narrow gaps to allow the pressure to escape without igniting the atmosphere outside of the equipment. Note! 2-2 Any substitution to non-recognized parts may impair safety.

Installation Manual 308014EN, Edition 4 May 2013 Rosemount Tank Radar REX Chapter 10 Mechanical Installation 10. Mechanical Installation To achieve precise and trouble free measurement, it is very important to mount the Radar Tank Gauge correctly on the tank. Please note that if an ullage plug is required, it has to be installed separately as there is no ullage plug on the Horn Antenna Gauge or the Parabolic Antenna Gauge. Note! 10.1 Please see the installation drawings for more information.

The display panel uses three wires: • Display panel supply voltage • Signal • Ground DS GND DS + DS Figure 11-14. Connecting a Remote Display Unit (RDU 40) or a DAU.
Installation Manual 308014EN, Edition 4 May 2013 Rosemount Tank Radar REX Chapter 12 Sensor Installation 12. Sensor Installation The TankRadar REX system includes various integrated equipment such as temperature sensors and Water Level Sensors. 12.1 Temperature Sensors Up to six temperature sensors can be connected to a REX Radar Transmitter Gauge (RTG). By using a Data Acquisition Unit (DAU) a maximum of 14 temperature sensors can be used in a tank.

Installation Manual 308014EN, Edition 4 May 2013 Rosemount Tank Radar REX Chapter 12 Sensor Installation For Custody Transfer applications, API chapter 7 recommends a minimum of one temperature sensor per 3 meters (10 feet) as shown in Figure 12-4. Emerson Process Management/Rosemount Tank Gauging may in some cases recommend a higher number of temperature sensors for tanks used for Custody Transfer, depending on how the tanks are operated.

The configuration distance in TankMaster refers to the distance above Zero Level T2-D T2 T1-D D Figure 12-5. Zero Level T1 T1, T2 etc. are sensor positions according to Required System Information (RSI) Form Configuration distance is measured from Zero Level.
Installation Manual 308014EN, Edition 4 May 2013 Water Level Sensor The Water Level Sensor (WLS) measures the free water level below an oil surface. It outputs a 4-20 mA signal which is connected to the level gauge. The WLS can also be equipped with integrated Multiple Spot Temperature sensors. Up to six temperature sensors can be connected to a Rosemount TankRadar REX transmitter. 12.2.
Installation Manual 308014EN, Edition 4 May 2013 Rosemount Tank Radar REX Chapter 12 Sensor Installation 12.2.2 Configuration It is important that the 4 mA and the 20 mA levels are properly configured in order to obtain correct water level readings from the WLS. The distance “X” between the Tank Zero Level and the Water Zero Level has to be considered when configuring the WLS. “X” can be calculated from known tank distances as illustrated in Fig. 12-8. Tank Reference point Mark wls_geometry_version2.
Installation Manual 308014EN, Edition 4 May 2013 Rosemount Tank Radar REX Chapter 12 Sensor Installation For inventory management with TankMaster WinOpi the WLS is configured in TankMaster WinSetup. The Lower Range Value (4 mA) and the Upper Range Value (20 mA) are given by the following formulas: Upper Range Value (20 mA) = LA + X Lower Range Value (4 mA) = X where LA is the active length of the Water Level Sensor, and X is the distance between the Water Zero Level and the Tank Zero Level.
Installation Manual 308014EN, Edition 4 May 2013 Rosemount Tank Radar REX Chapter 12 Sensor Installation The Water Zero Level is above the Tank Zero Level. In this case the 4 mA point on the WLS is above the Tank Zero Level. Note that when the 4 mA point is above the tank Zero Level the 4 mA value is positive, i.e. X>0. wls_open_above_v2.eps 20 mA X>0 Water Zero Level Tank Zero Level 4 mA 12-8 Example: LA=500 mm, X=70 mm. 4 mA value=70 mm. 20 mA value=500 + 70=570 mm.
