LDYA electromagnetic water meter
1. Product overview CHINT electromagnetic water meter is an intelligent water meter based on Faraday electromagnetic induction
principle, with high metering accuracy, wide measuring range and good reliability. The communication mode
supports 4G/RS-485, which can realize water consumption information monitoring and water consumption
reading. The use scenarios of electromagnetic water meters are generally industrial and commercial trade
measurement, residential water monitoring and assessment, etc.
Optional caliber: DN40-DN1200.
2. Product features ● Using plastic guide tube, no eddy current is generated; Corrosion resistance; Smooth inner wall, delaying scaling. ● Self-adhesive coils are wound, and the magnetic field is more uniform. ● The magnetic circuit board is formed by stamping, which is stable in structure, shockproof and durable. ● Integrated pressure measuring structure, no protrusion, no connection, no bump and no damage. ● Support two-way measurement ● The internal/external antenna can be selected, and the angle of the external antenna can be adjusted flexibly to adapt to various installation environments. ● The LCD screen is always on, no need to wake up, and it is more convenient to read meters on site. 3.
