M � -Nederlands Meetinstituut D e s c r i p t i o n Number TC3584 Revision 0 Project number 409580 Page 2of5 1 General information on the meter All properties, mentioned or not, of this meter, shall not be in conflict with the Dutch Weights and Measures Regulation "IJkregeling vloeistofineters en vloeistofineetinstal laties". This Test certificate describes an electromagnetic meter. Basically consisting of a cylindrical piece of piping with 2 magnetic spools and 2 electrodes and a Signal Converter, which is used to drive the magnetic spools and convert the electrode voltage to a flow rate. 1.1 Essential Parts 1.1.1 Measurement Sensor - Cylindrical pipe The cylindrical pipe which is internally covered with an insulating liner (either PP (polypropylene) or PFA(Teflon) liner is used). Through the liner the 2 electrodes are in contact with the liquid. Outside the pipe the 2 magnetic coils are mounted. Also see the Documentation Folder belonging to this Test certificate. 1.1.2 Signal Converter Exists of an explosion proof enclosure. 1.1.2.1 Essential parts of the Signal Converter - Back plane Used for all internal connections inside the Signal Converter. - Sensor board • Driving the magnetic coils inside the measurement sensor, and checks the current required for the coils. • Measures the induced voltage and processes the induced voltage to flow speed, flow rate, etc. Also validates the voltage sensing circuitry. • Communicates with the other modules through the GDC-bus. - Display module with optical keys • Displays all measurement values. The values presented and the format is programmable. The settings are secured with the "Weights and Measure" (W&M) jumper. • Read the 4 optical keys. These keys can be used for: paging through the 3 measurement pages, setting and changing of parameter via a menu system. • GDC master The GDC master controls all data traffic over the GDC-bus. If the master fails, measurements are not possible. All data communication over the GDC-bus is protected through CRC16 checksums. • GDC-bus port Is used for installing the Weights and Measures jumper. This locks all weights and measures parameters against changing. - Power supply Available are: • 100 - 230 VAC, 50/60 Hz • 12 - 24VDC 0 24 V AC/DC M � -Nederlands Meetinstituut D e s c r i p t i o n Number TC3584 Revision 0 Project number 409580 Page 3of5 - Output boards The output board(s) installed determine the possible outputs available. Possible are: • Basic 10 Module (IFC300 type CG300xx100) This board has the following outputs: Current Output including digital Hart protocol, Status output or Control input, Status output and single channel pulse output. The • EXI 10 Module (IFC300 type CG300xxAB0) This module has a basic layout. Depending on the required functionality, certain components are placed on the board. Possible are: ■ A= 2: Current output (active) with Hart protocol and pulse output (passive) ■ A= 3: Current output (passive) with Hart protocol and pulse output (passive) ■ B = 2: Current output (passive) and pulse output (passive)/Control input • Modular 10 (IFC300 type CG300xx4AB) This is a modular 10 board, providing: - Current output (active) with Hart protocol and a pulse output (active). - 2 places for modules (indicated with A and B) for extra outputs: A and B = 8: No module placed. A and B = C: Pulse output (active) or Current Output(active) for each module Remarks: The Hart protocol is superimposed on the DC current signal and enables the meter to communicate with other equipment. If pulses are used for the transmission of the measured volume to other equipment, the use of two pulse channels (also called double pulses) is mandatory. Both pulse channels must be shifted in phase. 1.2 Essential Characteristics - Measurement sensor • Characteristics stated on page 1 • Characteristics in the next table: Meter size DN25 DN50 DN80 DN100 Qmax [m3/h] 20 50 200 312,5 Qmin [m3/h] 1 2,5 10 15,6 MMQ [m3] 0,2 0,5 2 2 Meter size DN150 DN250 DN500 Qmax [m3/h] 500 2000 7875 Qmin [m3/h] 25 100 787,5 MMQ [m3] 5 20 100 Maximum Pressure : 16 bar(g) - The signal converter is either directly mounted on the measurement sensor (combined version) or is mounted separately from the measurement sensor (remote version) - The measurement sensor and the signal converter form a matched set. The exact physical properties of the measurement sensor are pre programmed into the signal converter. M � -Nederlands Meetinstituut D e s c r i p t i o n Number TC3584 Revision 0 Project number 409580 Page 4of5 - Working principle The magnetic field, generated through the 2 magnetic coils, induces a voltage across the flowing (conductive) liquid (Faraday's law for conductors moving through a magnetic field). This induced voltage is measured with the 2 electrodes and is directly proportional to the flow speed. By taking into account the pipe dimensions the flow rate can be calculated and displayed and outputted. By integrating over time the total measured volume can be calculated and displayed. The validity of the program and the parameters is continuously checked. If these checks fail an alarm is generated. 1.3 Essential Shapes 1.3.1 Inscriptions. - For the compact version: ■ At least the inscription TC3584 is mentioned on the data plate. - For the remote version: ■ At least the inscription TC3584 is mentioned on the measurement sensor and on the signal converter ■ The serial number of the signal converter is mentioned on the measurement sensor and/or The serial number of the measurement sensor is mentioned on the signal converter. 1.3.2 Sealing. See chapter 3 of this description. 1.4 Conditional Shapes - Cylindrical pipe The cylindrical pipe is constructed so that the combination of material and wall thickness is such that the influence due to changing liquid pressure is negligible. 1.5 Non essential Shapes The appearance of the data plate(s). 2 Conditions for Approval - If the meter is applied in a measuring system, it must be constructed in accordance with the Description and Documentation Folder belonging to this Test Certificate. 3 Sealing - Sealing of the measurement sensor against opening. - Sealing of the cover of the display of the signal converter against opening. Before sealing the "Weights and Measures jumper" is placed on the GC-bus of the display of the signal converter. This jumper prohibits the changing of the Weights and Measures parameters. - Sealing of the back cover of the signal converter. + Annex M1 Nederlands Meetinstituut Number TC3584 Revision 0 Project number 409580 Page 5of5 Performed tests on the meter: TEST PART TYPE TEST REPORT TEST HOUSE Accuracy tests Measurement sensor Optiflux 2000F CPC—409580—6 Krohne Altometer, Sizes DN25, DN50, and 4000F. witnessed by NMi DN80, DN100, Certin B.V.
