MAG 8000 water meter uncertainty To ensure continuous accurate measurement, flowmeters must be calibrated. The calibration is conducted at Siemens flow facilities with traceable instruments referring directly to the physical unit of measurement according to the International System of Units (SI). Therefore, the calibration certificate ensures recognition of the test results worldwide, including the US (NIST traceability). Siemens offers accredited calibrations assured to ISO 17025 in the flow range from 0.0001 m³/h to 10 000 m³/h. Siemens Flow Instruments accredited laboratories are recognized by ILAC MRA (International Laboratory Accreditation Corporation - Mutual Recognition Arrangement) ensuring international traceability and recognition of the test results worldwide. The selected calibration determines the accuracy of the meter. A standard calibration results in max. ± 0.4 % uncertainty and an extended calibration ± 0.2 % (for MAG 8000 irrigation ± 0.8 %). A calibration certificate follows every sensor and calibration data are stored in the meter unit. MAG 8000 (7ME6810) for Fire Service applicationsMAG 8000 (7ME6810) is FM Fire Service approved for automatic fire protection systems according to the Fire Service Meters Standard, Class Number 1044. The approval is applicable for the sizes DN 50, DN 80, DN 100, DN 150, DN 200, DN 250, and DN 300 (2", 3", 4", 6", 8", 10", and 12") with ANSI B16.5 Class 150 flanges. The FM Fire Service approved product can be ordered via the Z-options P20, P21 and P22. Grounding The sensor body must be grounded using grounding straps and/or grounding rings to protect the flow signal against stray electrical noise. This ensures that the noise is carried through the sensor body and a noise-free measuring area within the sensor body. For MAG 8000 Irrigation grounding rings on both sides are factory-mounted. | Metal pipes On metal pipes, connect the straps to both flanges. | | Plastic pipes On plastic pipes and lined metal pipes, optional grounding rings must be used at both ends. Grounding rings has to be ordered separately see “grounding ring kit” | | Combination of metal and plastic pipes A combination of metal and plastic requires straps for metal pipe and grounding rings for plastic pipe. |
Battery operation time and calculation The battery operation time depends on the connected battery pack as well as the operation condition of the meter. MAG 8000 calculates the remaining capacity every 4 hours and includes all consuming elements. Calculation compensates for temperature influence on battery capacity. The grafic shows the effect from other temperatures. A variation in temperature from 15 °C to 55 °C (59 to 131 °F) reduces the capacity by 17 % in the table from 15 Ah to 12.5 Ah. At typical revenue scenario of expected battery operation time can be seen in the table below. The measurement for calculating the rest capacity of the battery life time is only completed if the system has no active fatal faults or the empty pipe is active. Maximum battery specification is 10 years operation. Scenario - Revenue application | Output A | Pulse rate max. 10 Hz | Output B | Alarm or call-up | Meter dialog | 1 hour per month | Add-com | None | Temperature profile | | | |

External battery pack can be used as battery backup for mains power supply (if two cable entries in one cable gland are needed, order cable glands with two entries, see accessories on page 3/xx) Serial RS 232/RS 485 add-on communication modules are designed for mains powered systems as the battery operation time will be reduced. At 1 hour communication per month (all meter data collected 2 times per day) and the module is connected, the operation time is reduced to: - RS 232:
- low excitation frequency: 10 % of calculated operation time
- high excitation frequency: 80 % of calculated operation time
- RS 485:
- low excitation frequency: 50 % of calculated operation time
- high excitation frequency: 90 % of calculated operation time
