Biesheuvel Biesheuvel Instrument Technology Service On behalf of: International User s Association WIB and the manufacturer SIREP-WIB-EXERA report N T 2759 X 06 Index classification: /6.3 WIB Project: ZF APRIL INTRODUCTION 1.1 Scope and test objectives These tests have been designed to determine the capabilities and behaviour of TDR interface measurements under the following conditions: 1. show the performance of these devices in a single phase liquids. 2. determine the behaviour of the instrument on an emerging top layer. 3. determine the behaviour of the instrument to on an emerging bottom layer. 4. determine the behaviour of the instrument on separation of two liquids out of full dispersion with dominant top layer content. 5. determine the behaviour of the instrument on separation of two liquids out of full dispersion with dominant bottom layer content. 6. determine the behaviour of the instrument when exposed to liquid all the way up to the process connection. There are other behavioural aspects and uncertainties that have purposely been left out of this round of tests. The two liquids used are be water and paraffin oil.. Page 4 of 12 T 2759 X 06

8 1.2 The instruments This report describes the behavior of the Magnetrol Eclipse 705 coaxial when exposed to the tests as described under paragraph 1.4. The instrument submitted for the test is : Magnetrol Eclipse 705 coax type (head) A-A11 + (probe)7mt-a , s.n.: , Moore Industries signal converter HIM Smart HART Loop Interface and Monitor The instrument is that is subjected to these tests have the following basic specifications. selectable 4-20mA output for level or interface HART protocol. local display 24 Vdc powering 1 NPT process connection sensor length of 97.3 cm. The HIM Smart HART Loop Interface and Monitor ( further referred to as HIM converter) converts the digital information of the sensor into 2 separate 4-20mA signals, the first representing the interface level and the second the top level. During the tests a software update became available to further improve the performance and reaction on settling of an emulsion. For that reason all separation tests were conducted an additional 5 times The charts 5-2 to 14-2 do reflect the instrument performance of these additional tests. Each of the other tests were repeated 2 additional times to verify reproducibility and absence of undesired behavior. The results of these tests are included in the charts 1-2, 2-2, 3-2, 4-2, 15-2 and Working principle The instruments measure the distance from the top flange to the liquid level and the distance to an interface level. High frequency microwave pulses are coupled on a rod and guided along the probe. The pulses are reflected by the product surface and received by the processing electronics. A microprocessor identifies the echoes which are measured, evaluated and converted into a level information Some remaining energy of the microwave pulse is guided further along the rod and reflected by an interface with different dielectric value. The reflection of this interface is turned into an interface output. Page 5 of 12 T 2759 X 06

9 1.4 Test installation The test installation will consist of a transparent tube D=10 cm and H=120 cm The vessel will have 1. a bottom entry point for the test liquid. 2. a bottom connection point for the differential pressure reference measurement. 3. a side entry point for test liquid. From this point the liquid will be guided towards the wall. 4. a 50% level temperature point 5. a 10% level temperature point. A wire mesh is placed on the inside of the pipe. This acts as a Faraday cage. This however is not required for instruments with a coaxial design, like the unit that is described in this report.

13 3 RESULTS,FINDINGS AND COMMENTS These findings are summarized for ready reference, for detailed assessment of the performance of the instruments, the report and its appendices must be consulted in its entirety. 3.1 Hardware and software configuration of the instruments Hardware The input from the instrument to the HIM converter is connected according the installation manual as referred to as with Transmitter Excitation. This requires an external resistor. The terminals are marked as +TX and +IN. This connection uses a HART signal to transfer the data. The 24 V dc power is connected to the terminals marked as DC(+) and DC(-). The outputs to the data acquisition system are connected via the terminals marked +I source and I source. The terminal descriptions are somewhat cryptic and are thereby not self explanatory. Magnetrol anticipated on this by providing and additional page that provided guidance. The software update as mentioned in paragraph 1.2, were made available in a totally new head with electronics as a mechanical replacement of the original head Configuration The instrument as well as the HIM converter were supplied pre configured and needed no further adjustment. No adjustments were made to the settings after the replacement of the head. This does explain a systematic offset of the outputs of the additional test reported as Run 6 and Run 7. With a field replacement of the head, this offset correction can be done using the level Trim feature. 3.2 Instrument performance Accuracy and repeatability Water: Water [mm] accuracy repeatability hysterisis rising + 17 ± 2.5 falling + 24 ± rising +37 ± 2.5 falling +45 ± Oil: Oil [mm] accuracy repeatability hysterisis rising + 9 ± 1.5 falling + 0 ± rising +17 ± 1.0 falling +17 ± Page 10 of 12 T 2759 X 06

14 3.2.2 Oil on water The instrument starts to distinguish an emerging oil layer at a thickness of 22 mm. After this initial minimum oil layer thickness is established, the oil level is detected with an accuracy of ± 4 mm. The reaction of the level output is displayed in chart 3A-2, that of the interface output in chart 3B-2 and the level error is displayed in chart 3C-2. This test showed a repeatability of ± 1 mm. Remark: during run 4, some additional water was introduced into the pipe. This explains the increase in interface reading of this run Water under oil The instrument starts to distinguish emerging water after it has reached a thickness of 16 mm at the bottom of the probe. The maximum interface offset is 20 mm, after which the reading returns to a stable offset of 10 mm. The reaction of the level output is displayed in chart 4A-2 and that of the interface output in chart 4B-2. The error of the level reading is displayed in chart 4-2C and the error of the interface reading in chart 4D-2. This is all well within the specifications of the manufacturer. The additional test revealed a delayed detection of water at the end of the probe until a thickness of 24 mm is present Separation of a homogenous emulsion Separation of two liquids out of full dispersion with dominant top layer content. The column is filled with 100 cm liquid of with an water fraction of 2/3rd. The boundary between oil-emulsion and between emulsion-water are visually determined and plotted in chart 5 to 9 as a red and blue line. During mixing the level and interface outputs generate the same value. As soon as the mixing process is stopped,the separation start to occur. The subsequent runs resulted in continuously shortening settling times and the creation of a rag layer in the oil phase. This product deposits itself as sludge after it is broken up by a mixing action. The instrument started to generate correct interface values after the top layer has reached a thickness of 80 mm. Until that state is reached, the instrument first generates an output of the interface that corresponds to value of the liquid level The final interface reading, after total settling, has an offset of 10 mm The subsequent test runs are shown in chart 5-2 to Separation of two liquids out of full dispersion with dominant bottom layer content. The column is filled with 100 cm liquid with an oil fraction of 2/3rd. The boundary between oil-emulsion and between emulsion-water, are visually determined and plotted in chart 10-2 to 14-2 as a red and blue line. The subsequent runs resulted in the creation of a rag layer in the oil phase. The subsequent test runs are shown in chart 10-2 to Overfill behavior Overfill with oil The instrument correctly indicates the level of oil, even if the instrument is fully emerged during an overfill situation. This is displayed in chart 15-2 Page 11 of 12 T 2759 X 06

15 Overfill with water The instrument correctly indicates the level of oil even if the instrument is fully emerged during an overfill situation. This is displayed in chart Manufacturer s comments - The Eclipse Model 705 transmitter is designed to measure level, volume and interface with one transmitter. Local re-configuration of the transmitter from a level transmitter to an interface transmitter is accomplish with simple changes in the menu. These changes include the function & the entry of the dielectric of the top layer. Volume output can be accommodated via a 20-point strapping table. - The 4-20 ma output signal and the local LCD display can be autonomously set for either level, volume or interface values via the unit s menu. - The new Enhanced Eclipse Model 705 transmitter has 2 types of electronics, each providing all functions. The choice of electronics is determined by the required SIL level suitability. The standard electronics have a SFF of 84,5% and the SIL enhanced version offers a SFF of 91%. The manufacturer has a complete FMEDA report by Exida available at request. - Eclipse transmitters are delivered standard pre-configured from factory and an individual calibration and application record is kept at the factory to enable the manufacturer a quick and efficient troubleshoot support, if needed. - For applications suffering from heavy build up, enlarged interface probes to a diameter of 45mm, are available with the same performance and accuracy as the standard probe of 22mm diameter. - The 705 can be used for high pressure interface applications up to 430 bar (@ max. 90 C) This capability is not listed in the sales literature and is conditionally accepted after evaluation of the application by the manufacturer. - A full offer of by-pass cages and versions in combination with MLI s are standard available.
