Photoelectric direct reading remote transmission water meter
DN 15-50mm
LXSGZ dry direct-reading remote-transmission water meter is a direct-reading remote-transmission water meter that is convenient for remote reading and control. It uses M-BUS/RS485 bus communication to realize remote reading of water meter readings, effectively avoiding the management department's door-to-door meter reading. It makes meter reading more convenient and reliable, effectively improving work efficiency while saving manpower and material resources.
Product Features
◆Zero error: Utilizing unique direct-reading encoding technology, the meter reading moment directly reads the position status of the counter wheel, decodes it and transmits it to the system computer. The same value as the water meter window is displayed on the meter reading interface, regardless of time. , the influence of the environment and backflow, truly achieving zero error
◆ Passive direct reading: no need for power supply at ordinary times, only power supply at the moment of meter reading, long service life
◆ Does not affect the meter measurement accuracy: direct reading transmission The sensor part has no physical contact with the counter and other devices in the meter, which does not affect the measurement accuracy.
◆Electromagnetic compatibility: EMC testing meets the national standard requirements, overcoming the problem of direct-reading water meters being affected by external electromagnetic interference in accuracy and stability.
◆Unique address coding : Each meter has a unique address code belonging to this meter, which facilitates management and maintenance.
◆Fault protection: There is a fault protection device for bus open circuit, short circuit idle, etc.
