Technical Description 34 Water interface measurement The capacitive Water Level Sensor (WLS) continuously measures free water level below the oil surface and provides input for on-line net inventory. The sensor is integrated with the Multiple Spot Thermometer MST, see p. 22. It has a heavy duty design with no moving parts. The WLS outputs an analog 4-20 mA or a digital HART signal, which is connected directly to a radar gauge. There is a Pt100 temperature sensor inside the probe allowing temperature measurements at low levels. The WLS is welded to the MST to get a hermetic design. The open model WLS is suitable for crude oil applications and the closed model is suitable for lighter fuels such as diesel oil etc. A typical application The WLS is installed together with an MST to be hung from the top of the tank. The ver tical position is chosen according to the actual bottom water range. The WLS should be anchored to the tank bottom to ensure a fixed position in case of turbulence.

TankMaster HMI software TankMaster is a powerful Windows-based Human Machine Interface (HMI) for complete tank inventory management. It provides configuration, service and set up, inventory and custody transfer functions for TankRadar Rex systems. All calculations are based on current API and ISO standards. TankMaster follows the OPC standard and can communicate with Microsoft ® programs and OPC compatible systems like Intellution’s iFIX ® and Wonderware’s InTouch ® . TankMaster is developed and supported by Saab Rosemount Tank Control. TankMaster has two main software modules: WinSetup is the software package used for configuration of the total Rex system. SCADA Engineering OPC Client Level Ethernet TankMaster OPC Server TankMaster OPC Server TRL2 Field Bus FCU Management Modbus Modbus Modbus WinOpi is a complete inventory software package. The WinSetup package is included with all TankRadar Rex deliveries as a set-up and configuration tool. Other functions are options depending on which package is used. Available main functions in TankMaster include the following: Interactive configuration and installation with set-up wizard Inventory and custody transfer functions Real time tank gauging data such as level, temperature, water interface level and pressure. Real time, gross and net volume inventory calculations based on API and ISO. Hybrid tank gauging with pressure inputs giving data for density and mass calculation. Metrologically sealed data. API calculator. Tank Data, Level, Temperature, Pressure, Volume etc TankMaster distributes essential in ventor y tank gauging data. DCS PLC Saab TankRadar Rex 35
