The measuring part of the electromagnetic water meter consists of a cylindrical piece of piping with a square-like flow profile and 2 magnetic spools and 3 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 Description Document Remarks Measurement 10201-01 The inside of the cylindrical measuring tube is sensor provided with a square-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. printed circuit 10201-05 IFC 070 flow converter board 10201-06 Signal Converter and meter readin Mi Description Number T10201 Revision 0 Project number 812577 Page 2 of 5 1.2 Essential Characteristics 1.2.2 Flow characteristics Meter Flow rates [m3/h] size Minimum Transitional Permanent Overload Q1 Q2 Q3 Q4 DN50 01158 0,252 63 78,75 0,10 0,16 40 50 DN65 0,25 0,40 100 125 0,16 0,25 63 78,8 0,40 0,64 160 200 DN80 0,25 0,40 100 125 DN100 0,625 1,00 250 312,5 0,40 0,64 160 200 1,00 1,60 400 500 DN125 0,63 1,00 250 312,5 1,575 2,52 630 787,5 DN150 1,00 1,60 400 500 DN200 2,54 1 4,06 800 1000 1,58 2,52 630 787,5 1.2.3 Measuring principle In documentation 10201-01, paragraph 8.1, the measuring principle is described. 1.2.4 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. 1.2.5 Software specification (refer to WELMEC guide 7.2): • Software type P; • Risk Class C; • Extension L, while extensions D, S and T are not applicable. Software version Remarks 4.0.4 The software version is displayed after operating the right infrared key. Mi Description Number T10201 Revision 0 Project number 812577 Page 3 of 5 1.2.6 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 Manual 10201-01. The measured volume is presented by means of an electronic display The display register is built up as follows: Meter Indicating range Verification scale Size (minimum value) interval [m3] (maximum value) [mi] DN50 99.999 0,0001 DN80 until DN150 999.999 0,001 DN200 9.999.999 0,001 1.2.7 Accountable alarms If malfunctions are detected a visible alarm will be performed which remains present until the alarm is acknowledged and the cause of the alarm is suppressed. During the accountable alarms the registration of the volume in the totalizers is stopped. The validity of the program and the parameters is continuously checked. If these checks fail an alarm is generated. 1.2.8 Operating pressure range The measuring tube and measuring sensor may be used at an absolute pressure up to 10 bar. 1.3 Essential Shapes 1.3.2 Markings: - The markings have to fulfil the requirements stated in the legislation. - 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. An example of the markings is given in document no. 10201-04. M1 Description Number T10201 Revision 0 Project number 812577 Page 4 of 5 1.4 Conditional parts 1.4.1 Housing The housing of the Signal Converter consists of a metallic housing (compact and remote version). 1.4.2 Cabling remote reading When the meter is executed as a remote version the cable between the measuring sensor and reading unit should be mounted fixed. During use it should not be possible to move this cable. 1.4.3 Power supply The water meter is powered by one or two 3,6 Volts D-cell Lithium primary (non- rechargeable) batteries. The replacement date of the battery shall be indicated on the meter. A low battery alarm is generated one year before the meter stops functioning (based on actual settings and measuring situation). 1.5 Conditional characteristics 1.5.1 Programming Essential parameters (see documentation 10201-01) cannot be changed after the access control function (menu item 13) is set for "fiscal metering". In order to disable the "fiscal metering" a seal has to be broken, see documentation 10201-01 page 19 and 20. 1.5.2 Low flow cut off The low flow cut off is a programmable minimum flow. If the flow measured by the meter is below the programmed low flow cut off, the flow will be considered zero, so the meter reading will no longer change The programmed value cannot not exceed 10 mm/s, see documentation no. 10201-01 page 20. 1.5.3 Cylindrical pipe with a square-like flow profile The cylindrical pipe and the internal square flow profile is constructed so that the combination of material and wall thickness is such that the influence due to changing liquid pressure is negligible. 1.6 Non essential Shape 1.6.1 Alarm or pulse outputs MI Description Number T10201 Revision 0 Project number 812577 Page 5 of 5 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 measurement sensor against opening. - The cover of the display of the signal converter against opening. This makes it impossible to "unlock" the access control function (menu item 13). For unlocking this function, it is necessary to activate a hardware switch which is located inside the electronics unit. See documentation no. 10201-01 page 19. See the drawing no. 10201-03 for an example of the sealing. The securing component has to bear either: — A mark of the manufacturer laid down in an approved quality system by a Notified body, or; — A mark of a Notified body. 3 Conditions for conformity assessment 3.1 Bi-directional flow measurement During conformity assessment it is sufficient to verify a bi-directional meter only in one direction.
