[Product introduction]
MT1907 magnetoresistive sensing electronic water meter module is an electronic water meter module that uses low-power processor, non-contact polyphase magnetoresistive sensor (AMR) to detect impeller rotation and has no mechanical counter. It adopts the advantages of high measurement accuracy, small starting flow and wide range, and adopts intelligent electronic curve compensation technology to shorten the calibration time.

The module has NFC communication function. Users can read and set relevant parameters through mobile phones with NFC function.

[Product features]
● AMR magnetoresistive angle phase detection and metering technology, without mechanical counter components, directly samples the impeller rotation angle to calculate the consumption, with high metering accuracy and low starting flow;
● support forward / reverse flow metering;
● have NFC communication function;
● wide range measurement: 5-digit integer + 5-digit decimal display;
● LCD Chinese / English LCD displays cumulative consumption, alarm information, etc;
● large storage capacity: 12 months of monthly frozen data, 30 days of daily frozen data and current cumulative consumption;
● ultra low power consumption circuit design, battery life ≥ 7 years;
● magnetic interference warning. When disturbed by external magnetic field, LCD displays "interference" signal;
● battery undervoltage warning;
● data power-off protection function.
