MI Description Number T10003 revision 6 Project number 218464 Page 1 of 5 1 General information on the water meter All properties of this water meter, whether mentioned or not, will not be in conflict with the legislation. This EC type-examination certificate describes an electromagnetic water meter, which is exactly of the same construction as the electromagnetic meter described in Evaluation Certificate TC7161 and its Documentation Folder. 1.1 Essential Parts 1.1.1 Measurement Sensor - Cylindrical pipe The cylindrical pipe is internally covered with an insulating liner. 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 for details about the liner and the process connection of the meter. 1.1.2 Signal Converter 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 internal data-bus (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 Used for 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 • 24 V AC/DC - Output boards The output board(s) installed determine the possible outputs available. Possible are: • Basic 10 Module (IFC300F type CG300xx100) MI Description Number T10003 revision 6 Project number 218464 Page 2 of 5 This board has the following outputs: Current Output including digital Hart' protocol, Status output or Control input, Status output and single channel pulse output. • EXI 10 Module (IFC300F 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 (IFC300F 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, B = 8: No module placed. A, 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 water 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. 1.1.2.2 Essential shapes of the Signal Converter - Housing The housing of the Signal Converter consists of: • Metallic housing (compact and remote version). Optionally the housing is explosion proof. • Plastic housing for wall mounting (only possible for the remote version). 1.2 Essential Characteristics - Measurement sensor • Characteristics stated on page 1 of EC type-examination certificate no.

Menu item B3.4 and C5.2.5 See the manual in how to access the parameters. - The signal converter is either directly mounted on the measurement sensor (compact 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. MI Description Number T10003 revision 6 Project number 218464 Page 5 of 5 - 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, 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 Markings: - The markings have to fulfil the requirements stated in the legislation. - The data plate is fixed to the water meter and secured against removal by sealing or will be destroyed when removed. - For the remote version: • 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. The following seals are applied: - The measurement sensor against opening. - The cover of the display of the signal converter against opening. Before sealing the "Weights and Measures jumper" is placed on the GDC-bus of the display of the signal converter. This jumper prohibits the changing of the Weights and Measures parameters. 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 2 Conditions for Approval - If the water meter is used bi-directional, both flow directions must be included in the verification.
