1. An overview

Electromagnetic flow meter is designed specifically for the water industry to meet the city' s water supply to ensure the accurate calculation, the scene is widely used in places without power supply, such as urban water supply, sewage treatment, water conservancy and other industries.
Electromagnetic flow meter specially designed sensor excitation system, and high-performance lithium battery-powered systems, and uses 16-bit AMD embedded processor power, with all-digital signal processing, measurement stability, high measurement accuracy, anti - Interference ability, and other features, automatic bi-directional flow measurement, on-site instantaneous flow of positive and negative cumulative total to show that self-diagnosis alarm FAULT Far GSM wireless data functions, the user through the powerful GSM / GPRS remote management software system can flow Far total wireless data storage functions.

4. Display

The instrument for large LCD screen LCD, two-line display, scheduled for the last 10 cumulative flow shows that the greatest value 9, 999, 999, 999 display can be displayed alternate is, the reverse flow of the cumulative value of the schedule for the next five instantaneous flow shows that the largest display 99999 value can be displayed alternate is, the reverse flow of transient value and prompt report to the police.
Alarm Information Corrective measures.
Air Traffic Alarm Check whether the pipeline is full of fluid under test, to adjust air traffic control warning
Threshold adjustment factor and the air traffic control
Magnetically-shielded alarm system circuit Check excitation output signal cable wiring and sensors
Alarm signal output short-circuit Check signal cable wiring and sensor input
Check whether the appropriate scope of the range set to re-set range.

Limit traffic police Check the output pulse frequency settings are appropriate, pulse frequency output
Pulse output limit alarm Shall not exceed the maximum 1000HZ, re-set the maximum frequency

Check signal cable wiring and sensor input
Check whether the appropriate scope of the range set to re-set range.

Low-voltage battery alarm Battery replacement
GSM forced to send police GSM mandatory testing the use
