2 Page 1 of 6 1 General information on the water meter All properties of this water meter, whether mentioned or not, shall not be in conflict with the legislation. 1.1 Essential Parts 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 Signal Converter 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: VAC, 50/60 Hz VDC (grounding mandatory) 24 V AC/DC (grounding mandatory) - Output boards The output board(s) installed determine the possible outputs available. Possible are: Basic IO 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.

3 Page 2 of 6 EXI IO Module (IFC300 type CG300xxYZ0) This module has a basic layout. Depending on the required functionality, certain components are placed on the board. Possible are: Y = 2: Current output (active) with Hart protocol and pulse output (passive) Y = 3: Current output (passive) with Hart protocol and pulse output (passive) Z = 2: Current output (passive) and pulse output (passive)/control input (passive) Modular IO (IFC300 type CG300xx4YZ) This is a modular IO board, providing: Current output (active) with Hart protocol and a pulse output (active). 2 places for modules (indicated with Y and Z) for extra outputs: Y = 8: No module placed Y = A: Current output (active) Y = C: Pulse output (active) Z = 8: No module placed Z = A: Current output (active) Z = C: Pulse output (active) RS485 Modbus (IFC300 type CG300xxGYZ) The flow converter with RS485 interface is able to communicate with an external device using the Modbus protocol. Possible are: 2 places for modules (indicated with Y and Z) for extra outputs: Y = 8: No module placed Y = A: Current output (active) Y = B: Current output (passive) Y = C: Pulse output (active) Y = E: Pulse output (passive) Z = 8: No module placed Z = A: Current output (active) Z = B: Current output (passive) Z = C: Pulse output (active) Z = E: Pulse output (passive) 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 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).

Electronic revision number The electronic revision number is used to lay down the software version and the hardware of the instrument. If either changes, the number is updated. Approved electronic revision numbers: 3.2.4_; 3.2.6_; 3.2.7_; 3.3.0_; 3.3.1_; 3.3.2_; 3.3.3_; and 3.3.5_. The electronic revision number is stored under menu items B3.6 and C See the manual in how to access the parameters. Software specification: The first approved version of the water meter number. The approved software version is identified as: Main software: Menu items B3.3 and C5.1.5 User interface: 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. - Working principle The magnetic field, generated through the 2 magnetic coils, induces a voltage across 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 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 a seal or will be destroyed when removed.

This jumper prohibits the changing of the Weights and Measures parameters. 3 Conditions for Conformity Assessment - If the water meter is used bi-directional, both flow directions must be included in the verification.
