No: 306010E Saab TankRadar® Pro Introduction 1 Introduction Saab TankRadar Pro is a powerful radar level gauge suitable for non-contact level measurements in process tanks, storage tanks and other types of tanks. It is designed for easy installation and maintenance free operation. The modular hardware and software design makes it possible to specify a TankRadar Pro gauge that will meet your requirements now and in the future. The TankRadar Pro System The TankRadar Pro gauge offers a high degree of flexibility. It can be used as a stand-alone unit, or it can be connected to various control systems. You can integrate TankRadar Pro in your own Local Area Network (LAN). By using the Saab TRL/2 Bus interface you can easily connect Pro gauges to a Saab TankRadar L/2 system. Data Acquisition Unit Field Communication Unit Field Bus Modem TankRadar L/2 RTG 2930 RTG 40 A specially designed software package, Pro Setup, offers configuration and service capabilities. It also includes functions for presentation of measurement data. Edition 2. Ref. No: 306010E 1-1 Saab TankRadar® Pro Introduction RTG 40 Analog Instrument Display Panel HART Interface Analog Instrument Control System Hand Held HART Communicator If HART technology is used you can configure and monitor measurement data via a hand held communicator or a PC. For stand-alone systems, or as a complement to a PC or a control system, you can monitor level data using one or two analog outputs depending on the particular hardware configuration. As an option, your TankRadar Pro gauge can be equipped with an easy-touse display panel. It offers basically the same functionality as the Pro Setup software package. Four sturdy softkeys gives you access to configuration routines, service functions and level monitoring. 1-2 Edition 2. Ref. No: 306010E Saab TankRadar® Pro Introduction Measurement Principle The Saab TankRadar Pro transmitter sends a microwave signal with a continuously varying frequency towards the liquid surface. When the reflected signal returns to the antenna, it is mixed with the outgoing signal. Transmitted Reflected Frequency (GHz) fmax ∆f f1 ∆f ~ ∆t ~ d f0 fmin Time f1 f0 t0 t1 ∆t Since the transmitter continuously changes the frequency of the transmitted signal, there will be a difference in frequency between the transmitted and the reflected signals. The gauge mixes the two signals, resulting in a low frequency signal which is proportional to the distance to the liquid surface. This signal can be measured very accurately allowing fast, reliable and accurate level measurements. Saab TankRadar Pro uses an optimum microwave frequency, which reduces sensitivity to vapour, foam and contamination of the antenna, and keeps the radar beam narrow in order to minimize influence from walls and disturbing objects. Saab TankRadar Pro uses Fast Fourier Transformation (FFT), which is a well established signal processing technique, to obtain a frequency spectrum of all echoes in the tank. From this frequency spectrum the surface level is extracted. In combination with Saab´s echofixer, FFT allows meas- Edition 2. Ref. No: 306010E 1-3 Saab TankRadar® Pro Introduction urements in tanks with agitators, mixers and other disturbing objects. Saab´s echofixer provides a technique to adapt measurements to various situations, by using information from previous measurements. To further improve measurement accuracy, Saab TankRadar Pro can utilize the benefits of Saab´s Fast High Accuracy Signal Technique™ (FHAST™). Multiple Echo Tracking™ (MET™) is another advanced Saab TankRadar Pro feature, which provides increased resolution in tanks with disturbing objects. MET™ facilitates the separation of disturbances from the actual product surface echo. 1-4 Edition 2. Ref. No: 306010E Saab TankRadar® Pro Mechanical Installation 2 Mechanical Installation For optimum measurement performance the TR Pro gauge should be mounted according to the socket requirements and the free space requirements illustrated below.

To register a disturbing echo, do the following: TANK ECHOES Surface Echo 1 Echo 2 Echo 3 Echo 4 Echo 5 CNCL 10.543 -0.213 1.629 7.867 20.620 21.001 Move the cursor to the echo you want to add to the list. Click the Move the cursor to Add to list, and click the MARK button. Click the SAVE button to register the marked echo. Repeat steps 1 to 4 if you wish to register more disturbing echoes. EDIT button. The Set as surface option allows you to define an echo as the product surface. Mark the Add new false option if you want to manually add echoes. This may be a useful option if, for example, there are known disturbances below the product surface which can not be detected by the gauge at the time of installation. Click the CNCL button to return to the False Echo menu. To view the current list of registered disturbing echoes select the Reg. False Echoes option: 5-22 Edition 2. Ref.

Click the Select the Remove echo option and click the Click the EDIT SAVE button. MARK button. button to remove the selected echo. Mark the Add new false option if you want to manually add a false echo to the list of registered disturbing echoes. Mark the Clear list option if you want to remove the whole list of registered disturbing echoes. This option may be useful if you want to create a completely new list. See chapter 5 Pro Setup Software for further information on disturbance echo handling. We recommend that the Pro Setup software is used for configuration of tanks with several disturbance echoes. Edition 2. Ref. No: 306010E 5-23 Saab TankRadar® Pro Pro Display Panel 9. Select the Volume option from the Advanced Setup menu (optional). The Volume option allows you to setup the Pro transmitter for volume calculations. You can choose between using either a predefined tank shape like a sphere or a horizontal or vertical cylinder, or entering level and volume values into a strapping table When the configuration is finished you can start viewing measured data by returning to display mode. 5-24 Edition 2. Ref. No: 306010E Saab TankRadar® Pro Pro Display Panel Service The Service Menu allows you to view the configuration status, edit holding registers, reset holding registers to factory values, do a software reset or to start a search for the surface echo. Information about antenna type, software versions, operation time, error status and unit code is available. You can also start a search for the surface echo and reset some of the holding registers to factory settings. The service functions should only be used if you are familiar with the advanced functionality of TankRadar Pro. Config Report Shows information on antenna type, software versions, software and hardware configuration, operation time, error status and unit code. Please provide this information if you contact Saab Tank Control for trouble shooting. Echo Search Starts a search for the surface echo. Factory Settings Resets selected holding registers to factory settings. Software Reset Use this option to trigger the software start up procedure. Super Test Enables all software options (Echofixer, MET, FHAST, Strap Table) for one week. Use this option if you want to test options not available in your transmitter.

Contact your local representative for this password if you need to use the Advance Service option. Edition 2. Ref. No: 306010E 5-25 Saab TankRadar® Pro Pro Display Panel 5-26 Edition 2. Ref. No: 306010E Saab TankRadar® Pro Tank Distances 6 Tank Distances Definitions The Distance Offset (G) is defined as the distance between the upper reference point and the flange (the flange is referred to as the Tank Radar Pro Reference Point). You can use G to specify your own reference point at the top of the tank. Set G=0 if you want the flange as upper reference point. G is defined as positive if you use an upper reference point above the TR Pro Reference Point. For tanks equipped with an ullage plug for hand dipping the Tank Ullage Reference Point (dipping mark) can be used as upper reference point, but you can use other reference points as well. Tank Ullage Reference Point Tank Radar Pro Reference Point G>0 Tank Level Reference Point G<0 Edition 2. Ref. No: 306010E 6-1 Saab TankRadar® Pro Tank Distances The Tank Height (R) is defined as the distance between the upper reference point (specified by the Distance Offset G) and the lower reference point (zero level). If no datum plate or zero level exist the tank bottom usually is used as zero reference point. In this case C=0. The Minimum Level Offset (C) is always positive and is defined as the distance between the zero level (Tank Level Reference Point) and the minimum accepted level. Normally you set the C distance in order to extend the measurement below your zero reference point. The Hold Off (H) distance defines how close to the TR Pro reference point a level value is accepted. Normally the Hold Off distance does not need to be changed. However, if there are disturbing echoes in the upper part of the tank, for example from the tank nozzle, you can increase the Hold Off distance in order to avoid measurements in the region close to the antenna. 6-2 Edition 2. Ref. No: 306010E Saab TankRadar® Pro Tank Distances Examples The following examples illustrate how you can set the various tank distance parameters to suit your own preferred reference point settings.
