MAG 8000 GSM/GPRS Wireless Communication Module

The MAG 8000 GSM/GPRS wireless communication module provides the latest mobile technology using a Quad Band (850/900/1800/1900 MHz) module.
The GSM/GPRS module logs data from the MAG 8000 memory and from the two analog inputs (one 4 to 20 mA not powered by the module and one 5 V
ratiometric powered by the module) and
storage in the internal memory and later transmit it into a system or PC via email or SMS.
An additional synchronization function secures the initial collection time of the data independent of the sample rate used.

The GPRS technology makes it possible to send a higher amount of data via email. The data is secured using a POP 3 server configuration avoiding
encryptions that require additional software. The configuration of the module is performed via SMS commands that allow you to define the users,
email accounts, transmission settings, collection, etc.
The GSM/GPRS module is a compact built-in solution which can be installed in the existing MAG 8000 with SW version 3.02 and higher.
The battery lifetime will depend on signal strength and especially on the number of transmissions. Therefore we recommend an optimal setting of
transmission once a day (see page 3/121).
The module also includes the same power management algorithm that secures a very good calculation of the remaining battery lifetime.
The OPC server specifically designed for the MAG 8000 GSM/GPRS module is offered free of charge. With this valueadded package, the opportunity
for measurement data collection and further processing/analyzing for system integration and automation is offered.

MAG 8000 is a microprocessor-based water meter with graphical display and key for optimum customer operation and information on site. The
transmitter drives the magnetic field in the sensor, evaluates the flow signal from the sensor and calculates the volume passing through. It
delivers the required information via the integrated pulse output or communication interfaces as part of a system solution. Its intelligent functionality,
information and diagnostics ensure optimum meter performance and information to optimize water supply and billing.

 The SIMATIC PDM tool gives the possibility of testing and verifying the flowmeter on site and creating a printed ”Qualification Certificate” with all
specific data that define the quality status of the measurement.
The Qualification Certificate consists of two pages with information about the actual status of the sensor:
 Part 1 provides general settings, sensor and battery info, totalizer values and pulse output settings.
 Part 2 provides detailed information about electronic and sensor functionality and a main parameter list for evaluating the functionality of the MAG 8000 water meter.

MAG 8000 water meter uncertainty
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.

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.

MAG 8000 (7ME6810) for Fire Service applications
MAG 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

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.
A variation in temperature from 15 °C to 55 °C (59 to 131 °F) reduces the capacity by 17 % 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.

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)
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
