[product introduction]
MT2002 magnetoresistive sensing electronic water meter module is an electronic water meter module with valve control function, which uses low-power processor and non-contact polyphase magnetoresistive sensor (AMR) to detect impeller rotation. It adopts the advantages of high measurement accuracy, small starting flow and wide range. It adopts intelligent electronic curve compensation to shorten the calibration time.

[functional features]
● magnetoresistive angle phase detection and metering technology is adopted, without counter components, directly sampling impeller rotation angle to calculate consumption, with high metering accuracy and low starting flow;
● support forward / reverse flow metering;
● wide range measurement: 5-digit integer + 5-digit decimal display;
● 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: in case of external magnetic interference, LCD displays "interference" signal;
● early warning of battery undervoltage;
● prepayment and post payment management, real-time settlement;
● residual water volume alarm function;
● data power-off protection function;
● valve control function;
● water return function: after the water meter is recharged, partial water return operation of the water meter can be carried out;
● reset function of recharge data in the table.
