M � Description Number T10201 Revision 4 Project number 11200810 Page 2 of 4 1.2.2 Measuring principle In documentation 10201-01 the measuring principle is described. 1.2.3 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. 1.2.4 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 versions Remarks 4.0.4, 4.0.10, 4.0.11, The software version is displayed after 4.0.12, 4.2.2_ operating the right-hand infrared key. 1.2.5 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 documentation 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 interval Size [m3] [m3] DN25 99.999.999 0,00001 DN40, DN50, DN65 and 99.999.999 0,0001 DN80 DN100, DN125, DN150, 99.999.999 0,001 DN200 and DN250 DN300 99.999.999 0,01 The parameter "counter multiplier value" has to be set to 1. See documentation 10201-01. 1.2.6 Accountable alarms If malfunctions are detected a visible alarm will be displayed 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. 1.2.7 Maximum operating pressure: - 16 bar(g) for sizes DN200 and smaller; - 10 bar(g) for sizes DN250 and larger. M � Description Number T10201 Revision 4 Project number 11200810 Page 3 of 4 1.3 Essential Shapes 1.3.1 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 documentation 10201-04. 1.3.2 Signal converter The signal converter is mounted either: - Directly on the measurement sensor, this is called the compact version. - Separately from the measurement sensor, this is called the remote version. A single shielded cable connects the sensor to the signal converter. 1.3.3 Inlet pipe and outlet pipe Minimum straight inlet pipe: 0 D Minimum straight outlet pipe: 0 D 1.4 Conditional parts 1.4.1 Housing The housing of the Signal Converter consists of either: - a metallic housing, compact and remote version; - a plastic housing, compact version only. See documentation 10201/02-03. 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 is set for "fiscal metering". In order to disable the "fiscal metering" a seal has to be broken, see documentation 10201-01. The access control function is menu item 13 for software versions 4.0.x_I'l and menu item 1 for software versions 4.2.x I'l. See documentation 10201-01. 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 and the meter reading will no longer change The programmed value cannot not exceed 10 mm/s, see documentation no. 10201-01. �'� With x being any number. M � Description Number T10201 Revision 4 Project number 11200810 Page 4 of 4 1.5.3 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. 1.6 Non essential parts - Single channel pulse output (optional). This is an extra printed circuit board stacked to the printed circuit board mentioned in paragraph 1.1. This pulse output may not be used for the legal transmission of measured volume. - Temperature and pressure sensor and transmitter, compact version only (optional). The temperature and pressure sensor are mounted in the measurement sensor. The corresponding electronics is mounted in the signal converter. The measured value can be displayed for information purposes only. The values may not be used for conversions. 1.7 Non essential shapes - Alarm and pulse outputs (double channel for legal transmission of the measured volume) 2 Seals The following seals are applied: - The data plate is fixed to the water meter and secured against removal by seal or it will be destroyed when removed. - The hardware switch located inside the electronics unit is sealed against activation. This prevents the access control function (see paragraph 1.5.1) from being unlocked. - The electronics unit is sealed against removal. See the drawing numbers 10201-03, 10201/02-03 and 10201/02-04 for examples of the seals. 3 Conditions for Approval - Bi-directional flow measurement During conformity assessment it is sufficient to verify a bi-directional meter only in one direction.
