Saab TankRadar® Pro Introduction1-3Edition 2. Ref. No: 306010EMeasurement PrincipleThe Saab TankRadar Pro transmitter sends a microwave signal with a con-tinuously varying frequency towards the liquid surface. When the reflectedsignal returns to the antenna, it is mixed with the outgoing signal.Since the transmitter continuously changes the frequency of the transmit-ted signal, there will be a difference in frequency between the transmittedand the reflected signals.The gauge mixes the two signals, resulting in a low frequency signal whichis proportional to the distance to the liquid surface. This signal can bemeasured very accurately allowing fast, reliable and accurate level measure-ments.Saab TankRadar Pro uses an optimum microwave frequency, which reducessensitivity to vapour, foam and contamination of the antenna, and keepsthe radar beam narrow in order to minimize influence from walls anddisturbing objects.Saab TankRadar Pro uses Fast Fourier Transformation (FFT), which is awell established signal processing technique, to obtain a frequency spec-trum of all echoes in the tank. From this frequency spectrum the surfacelevel is extracted. In combination with Saab´s echofixer, FFT allows meas-fmaxFrequency (GHz)Time∆ff1∆f ~ ∆t ~ dt0∆tfminf0t1TransmittedReflecteddf0f1

No: 306010Eurements in tanks with agitators, mixers and other disturbing objects.Saab´s echofixer provides a technique to adapt measurements to varioussituations, by using information from previous measurements.To further improve measurement accuracy, Saab TankRadar Pro can utilizethe benefits of Saab´s Fast High Accuracy Signal Technique™(FHAST™).Multiple Echo Tracking™ (MET™) is another advanced Saab TankRadarPro feature, which provides increased resolution in tanks with disturbingobjects. MET™ facilitates the separation of disturbances from the actualproduct surface echo.

No: 306010E4Select the Configuration tab1 Click the Read button.Response: the current settings are displayed.2 In the Tank Geometry box, enter values for Distance Offset (G),Tank Height (R) and Minimum Level Offset (C).The Distance Offset (G) is defined as the distance between theupper reference point and the flange (the flange is referred to as theTank Radar Pro Reference Point). You can use G to specify yourown reference point at the top of the tank. Set G=0 if you want theflange as upper reference point. G is defined as positive if you usean upper reference point above the TR Pro Reference Point. Fortanks with an ullage plug for hand dipping the Tank Ullage Refer-ence Point (dipping mark) can be used as upper reference point,but you can use other reference points as well.The Tank Height (R) is defined as the distance between the upperreference point (specified by the Distance Offset G) and the lowerreference point (zero level).The Minimum Level Offset (C) is used to extend the measurementrange down to the tank bottom. C can not be a negative value. C isdefined as the distance between the zero level (Tank Level Refer-ence Point) and the minimum accepted level. If your zero level islocated above the bottom of the tank, set the C distance equal to
Saab TankRadar® Pro Pro Setup4-19Edition 2. Ref. No: 306010Ethe distance between the zero level and the tank bottom. Set C=0 ifyou use the tank bottom as zero reference point.The Hold Off (H) distance defines how close to the TR Pro refer-ence point a level value is accepted. Normally the Hold Off dis-tance does not need to be changed. However, if there are disturbingechoes in the upper part of the tank, for example from the tanknozzle, you can increase the Hold Off distance in order to avoidmeasurements in the region close to the antenna.The Calibration Distance is by default set to zero. It can be used tocompensate for systematic errors due to e.g. disturbances from thetank nozzle which may be case if the gauge is not mounted properlyaccording to the free space requirements.See chapter 6: Tank Distances for further information on how to setthe tank geometry parameters.3 Click the Store button.

Normally, linear interpolation isthe preferred method. For spherical tanks, quadratic interpolationmay result in a smaller error. However, it may be necessary to tryboth methods in order to evaluate which one is best in your particu-lar case. By using linear interpolation and a sufficient number ofvalues in the strapping table, the interpolation error can normally bereduced to a minimum.3 Click the Store button.

No: 306010E7Disturbance Echo HandlingPro Setup offers you powerful tools to handle disturbing echoes.The False Echo tab displays a list of echoes detected by the Protransmitter. To optimize measurement performance you canregister false echoes which are due to disturbing objects in thetank like beams, agitators and heating coils.The Spectra-Threshold tab shows the amplitude of the meas-ured signal along the tank. This diagram is often used to obtainan overview of the conditions in the tank. You can use this dia-gram to set a general Amplitude Threshold level in order tofilter out disturbing noise. You can also design an AmplitudeThreshold which is a function of distance from the transmitterto the tank bottom.

No: 306010ESetting a general amplitude threshold1 Click the Read buttonResponse: a spectrum is displayed showing the radar amplitude vs.distance from the gauge to the product surface (ullage).2 Set the general Amplitude Threshold. Echoes with amplitudesbelow the general amplitude threshold will be disregarded. Recom-mended threshold value:Calm conditions: no turbulence, foam or condensation. Set ampli-tude threshold to approximately 20% of surface echo amplitude.Foam, agitators: check amplitude of surface echo when foam ispresent or agitator is running. Set amplitude threshold to approxi-mately 30% of surface echo amplitude.Note that these figures are approximate estimations. Significantdeviations from these figures may be have to be used in manycases.Creating a customized noise threshold tableYou can filter out weak disturbing echoes by creating a noisethreshold table. This technique should only be used in specialsituations, for example at the bottom of tanks with weak disturbingechoes. In such tanks the transmitter may lock at disturbancesclose to the bottom when the tank is empty. Setting up a noisethreshold in this region will guarantee that the transmitter startsfollowing the surface when the tank is filled again.Generalamplitudethreshold

By using this techniquethe risk of locking to a disturbance echo close to the tank bottomis eliminated. This technique is particularly useful in tanks withweak bottom echoes, like e.g. tanks with cone shaped outlets. Inthis case you should also make sure that the Tank Presentation/Bottom_echo_always_visible parameter is not set (see the de-scription of Start Radar tab).InfluencefromnozzleInfluence from pipe inside the tank
Saab TankRadar® Pro Pro Setup4-29Edition 2. Ref. No: 306010ERegistration of False EchoesThe False Echo function allows you to let the transmitter registerdisturbing echoes caused by objects in the tank. This makes itpossible to detect a product surface close to a disturbance echoeven if the surface echo is weaker than the disturbing echo.1 Select the False Echo tab2 Click the Read button to update the list of interfering echoes.The right-hand list displays disturbances that was detected by thetransmitter. In order to optimize the measurement performance, youmay need to register interfering echoes as described below.Note! Registration of disturbing echoes requires that Saab´s echofixer isenabled.When should I register?See the following recommendations before you register new interferingechoes:• Make sure that a correct amplitude threshold is set before youregister any disturbance echoes. See description of the Spectra-Threshold window• Keep the number of registered echoes to a minimum.• Compare the list of interfering echoes with the tank drawing or byvisible inspection of the tank. Note if there are objects like beams,heating coils, agitators etc. which correspond to the found echoes.Only register echoes which can be clearly identified as objects inthe tank.
Saab TankRadar® ProPro Setup4-30Edition 2. Ref. No: 306010E• Make sure that the level is stable before you register a disturbanceecho. A fluctuating level may indicate a temporary disturbancewhich is not due to an interfering object.• Do not register a disturbing echo if the amplitude is below thegeneral amplitude threshold, see description of the Spectra-Thresh-old window.• Do not register a disturbing echo if the amplitude is significantlysmaller than the amplitude of the surface echo when the surface isat the same level as the disturbance. (In some cases weak disturb-ing echoes can be filtered out by creating a noise threshold table,see description of the Spectra-Threshold window).• It may be necessary to register new disturbance echoes at a laterstage when objects have become visible due to surface movement.Example 3:This example illustrates a signal spectrum resulting from a tankwith an agitator. The product level is slightly below the agitatorin this example. In a case like this it is recommended that thedisturbing echo is registered, in order to achieve reliable meas-urements when the product surface is passing the agitator. Ofcourse this is true also for disturbing echoes resulting from othertypes of objects.SurfaceAgitator
