[Product introduction]
Mt1908 magnetoresistive sensing electronic water meter module adopts low-power processor and non-contact polyphase magnetoresistive sensor (AMR) to detect impeller rotation. It is an electronic metering module without mechanical counter. This measurement method has the advantages of high measurement accuracy, small starting flow, high sensitivity and high range ratio. The intelligent electronic curve compensation technology is adopted to shorten the calibration time. Ultra small screen LCD display, suitable for small movement single flow meter or volume meter.

[Functional features]
● AMR angle and phase detection metering technology, without 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;
● wide range measurement: 5-digit integer + 5-digit decimal display;
● ultra small screen LCD Chinese / English LCD display cumulative consumption, alarm information prompt, 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 the water meter is subject to external magnetic interference, LCD displays "interference";
● battery undervoltage warning;
● data power-off protection.
