The photoelectric water meter is a new era of Internet of Things water meter with rotary cold water meter as the base meter, equipped with communication module, and communicates with the management center through wired connection to carry out wireless meter reading, network recharge, remote control, fault detection and other functions.

 The CZ6510 is a direct-reading remote meter: instead of counting pulses and inferring volume, a photoelectric encoder reads the actual position of the digit wheels on the register. The reading you get is the reading on the dial - the same number a meter reader would see, delivered over the bus without anyone visiting the meter. This matters most where billing disputes and reconciliation occur. Pulse systems accumulate and can drift if a pulse is missed; direct reading returns an absolute value every time, so the platform, the bill and the meter always agree. Power only flows at the moment of reading - the meter is normally dormant and needs no battery when on an M-Bus/RS485 bus that supplies power over the same two wires. Readings are triggered on schedule or on demand. Base meter is our rotary vane mechanical register (DN15–DN50, threaded), with accuracy per ISO 4064. Typical deployments: apartment blocks, dormitories and commercial buildings where meters are concentrated and a wired bus to one collector is economical.

FAQ：

Q: What is the difference between direct reading and pulse output?

A: Pulse meters count electronic ticks and compute volume - one missed tick means a small permanent error. Direct reading photographs the digit wheel position, so every read is an absolute value that matches the dial exactly. For billing, direct reading is the defensible option.

Q: Does it need a battery?

A: Not on a powered bus. M-Bus supplies power over the same two-wire bus used for reading, so the meter stays dormant and battery-free. Battery versions exist for wireless deployments - different model line.

Q: What happens to data during a power cut?

A: Nothing is lost - the volume lives on the mechanical digit wheels, which need no power. When the bus returns, the next read picks up the current value. This is the core advantage over electronic-only registers.

Q: How many meters can one bus carry?

A: A standard M-Bus segment handles up to 250 meters; larger installations use repeaters/level converters to scale further. Send your meter count and building layout and we will size the bus topology.
