[Product Profile]
MT1903 Magnetoresistance Sensing Electronic Water Meter Module is a low-power processor, non-contact multiphase magnetoresistance sensor (AMR) to detect impeller rotation, no mechanical counter, valve-controlled electronic water meter module. It has the advantages of high metering accuracy, small starting flow, wide range, etc. It uses intelligent electronic curve compensation to shorten the calibration time.

[Functional characteristics]
Adopt reluctance angle phase detection metering technology, without counter components, directly sample the calculation amount of impeller rotation angle, with high metering accuracy and low starting flow;
Supporting positive/reverse flow measurement;
Broad range measurement: 5-digit integer + 5-digit decimal display;
LCD Chinese/English LCD display cumulative usage, alarm information prompts, etc.
Large storage capacity: frozen data for 12 months, frozen data for 30 days and current cumulative usage;
Circuit design with ultra-low power consumption, battery life > 7 years;
Early warning of magnetic interference: LCD displays "interference" signal when external magnetic interference occurs;
Early warning of battery undervoltage;
Pre-payment and post-payment management and real-time settlement;
Waterfall alarm function;
Data outage protection function;
Function of valve control;
Backwater function: partial backwater operation can be carried out after the water meter is filled;
Function of zero clearing of recharge data in the table.
