MI Description Number T10350 revision 1 Project number 218464 Page 1 of 5 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 1.1.1 Measurement Sensor The inside of the cylindrical measuring tube is provided with a rectangular-like flow profile. The internal flow sensor is covered with an insulating liner. Through the liner, the 3 electrodes are in contact with the liquid. The flow sensor is equipped with 2 magnetic coils. 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) This board has the following outputs: Current Output including digital Hart® protocol, Status output or Control input, Status output and single channel pulse output. MI Description Number T10350 revision 1 Project number 218464 Page 2 of 5 • 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 1.2.1 Measurement sensor • Characteristics stated on page 1 of the EC type-examination certificate. • Further characteristics are given in the following table: Flow rates [m3/h] Meter Ratio size Minimum Transitional Permanent Overload Q3/Q1 Q1 Q2 Q3 Q4 0,025 0,04 10 12,5 400 DN25 0,04 0,064 16 20 400 0,0625 0,1 25 31,3 400 DN40 0,1 0,16 40 50 400 0,1 0,16 40 50 400 DN50 0,1575 0,252 63 78,75 400 0,1575 0,252 63 78,75 400 DN65 0,25 0,40 100 125 400 MI Description Number T10350 revision 1 Project number 218464 Page 3 of 5 Flow rates [m3/h] Meter Ratio size Minimum Transitional Permanent Overload Q3/Q1 Q1 Q2 Q3 Q4 0,25 0,40 100 125 400 DN80 0,40 0,64 160 200 400 0,40 0,64 160 200 400 D N 100 0,625 1,00 250 312,5 400 0,625 1,00 250 312,5 400 DN125 1,00 1,60 400 500 400 1,00 1,60 400 500 400 DN 150 1,575 2,52 630 787,5 400 1,575 2,52 630 787,5 400 DN200 2,54 4,06 800 1000 315 DN250 2,5 4 1000 1250 400 DN300 4,0 6,4 1600 2000 400 • The following characteristics are applicable for all sizes: Maximum admissible pressure (bar) 10/ 16 Min/max admissible temperature (°C) +0,1 /+50 Orientation All positions Power supply Type mains AC DC AC/DC Umax 230 V 24 V 24V Umin 100 V 12 V 24V Frequency 50—60 Hz - - • Electronic revision number The electronic revision number is used to lay down the software version and the hardware of the instrument.

MI Description Number T10350 revision 1 Project number 218464 Page 4 of 5 - 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 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. 1.2.2 Bi-directional flow The sensor can be used to measure flow in forward and reverse directions. See also the conditions as stated in chapter 3. 1.2.3 Operation and presentation of legal data The meter is standard equipped with an electronic display and can be operated using the infrared keys on the display module. The operation is further described in Chapter 6 of the IFC300 handbook. The measured volume is presented by means of an electronic display The display settings are as follows: Meter Indicating range Verification scale interval Size [m3] [m3] DN25 99.999 0,00001 DN40, DN50, DN65 and 999.999 0,0001 DN80 DN100, DN125, DN150, 9.999.999 0,001 DN200 and DN250 DN300 99.999.999 0,01 1.2.4 Maximum operating pressure: - 16 bar(g) for sizes DN200 and smaller; - 10 bar(g) for sizes DN250 and larger. 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: MI Description Number T10350 revision 1 Project number 218464 Page 5 of 5 • 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 Inlet pipe and outlet pipe Minimum straight inlet pipe: 0 D Minimum straight outlet pipe: 0 D 1.4 Conditional shapes - Cylindrical pipe with a rectangular-like flow profile The cylindrical pipe and the internal rectangular like flow cross-section profile are constructed so that the combination of material and wall thickness is such that the influence due to changing liquid pressure is negligible. 2 Seals The following seals are applied: - The data plate is fixed to the water meter and secured against removal by sealing or will be destroyed when removed; - 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. 3 Conditions for Approval - Bi-directional flow measurement During conformity assessment it is sufficient to verify a bi-directional meter only in one direction.
