I. Product Introduction:

       YYDG water supply dedicated electromagnetic flowmeter has strong anti-interference ability, can quickly capture flow changes, and improve measurement accuracy. The lining material meets drinking water standard requirements; rich self-diagnosis functions, noise suppression, and anti-interference functions ensure more stable measurement; high accuracy class up to 0.2; high signal resolution that can achieve the best range ratio, suitable for small flow measurement at night.

II. Product Features:

       Parameter wizard function for quick and accurate product setup;

       Infrared buttons, no need to open the cover for menu settings;

       Wiring self-check diagnosis function to prevent wiring errors;

       Free switching between Chinese and English menus;

       Rich data recording functions, including power on/off records, parameter modification records, historical data records, etc;

       Noise suppression and anti-interference functions;

       Rich self-diagnosis functions, such as empty pipe, excitation failure, etc;

       Sensor magnetic field simulation, excitation frequency adjustable from 1.5625HZ-25HZ, adaptable to different working conditions, accuracy up to 0.2 class;

       Damping adjustable between 0.1-200S, smaller damping time means faster response, larger value means more stable flow, suitable for filling applications;

       Flexible product iteration and backward compatibility.
