Product overview

Direct reading of the mechanical register through a wired interface.

This water meter uses photoelectric sensing to read its register rather than relying solely on accumulated pulses. Longzhida lists RS-485 and M-Bus reporting forms, with a rotary-vane measuring structure. The communications protocol and power arrangement should be matched to the meter-reading system; the supplier’s zero-error wording is not treated as an accuracy guarantee.
