OverView
7ME6910-1AA10-1AA0 is a SITRANS F M MAG 8000 series electromagnetic flowmeter, specially designed for liquid flow measurement in industrial pipelines. It needs to be used with electromagnetic sensors specified by Siemens (such as MAG1100, MAG3100, MAG5100W, etc. series) to complete flow measurement.
FAQ:
1.Can the trigger threshold of the empty traffic detection function of 7ME6910-1AA10-1AA0 be customized?
7ME6910 – 1AA10 – 1AA0, as a transmitter of the MAG5000 series, its empty pipe detection trigger threshold supports customization, and the threshold adjustment can match different on-site working conditions to avoid false alarms:
- Panel “Basic settings” → “Empty pipe cut-off” parameter adjustment, the default is about 500% (full pipe resistivity is the basis);
- Need to meet: fluid conductivity ≥20μS/cm, split installation with double-shielded cable (≤50 meters).
When customizing and turning on the empty pipe detection function, the conductivity of the measured fluid must be ≥20 μS/cm; and because this model is suitable for split electromagnetic flowmeters, it needs to be equipped with a special double-shielded cable (double shielding of the wire and the total shielding layer, length ≤50 meters), otherwise it may affect the accuracy of the threshold detection, resulting in abnormal alarms.
2.When 7ME6910-1AA10-1AA0 is adapted to DN150 pipes, what are the corresponding sensor models and mounting flange standards (such as PN16/PN25)?
When 7ME6910 – 1AA10 – 1AA0 is adapted to DN150 pipes, the corresponding sensor and mounting flange standards have clear adaptation models and specifications, as follows:
- Sensor model: MAG 3100P (DN150 model), MAG 5100W (DN150 model);
- Flange standard: PN16 (MAG 3100P), PN16/AS 4087 (MAG 5100W);
It should be noted that the MAG1100 series sensor adapted to this transmitter has a maximum nominal size of only DN100 and cannot be adapted to DN150 pipes, so it is not an adaptation choice in this scenario.
3.7ME6910-1AA10-1AA0 When measuring conductive liquid containing solid particles, what is the maximum allowable solid particle size?
7ME6910 – 1AA10 – 1AA0 There is no separate clear limit for the maximum allowable particle size of conductive liquid containing solid particles. The specific requirements depend on the paired sensor, and the overall system focuses more on limiting the solid content ratio.
7ME6910 – 1AA10 – 1AA0 has no hard limit on particle size. In actual use, as long as the solid content is controlled within the adaptation ratio of the corresponding sensor, and a sensor with an appropriate lining is selected based on the particle hardness, conductive liquids containing solid particles can be stably measured.
