What metering equipment do water-abstraction permit rules require at intakes, and can the LGF-PA66 meet remote-supervision requirements?

Water-abstraction permit rules require the abstractor to install qualified metering at the intake — one meter per well or offtake — and the data feeds water-resource fee (tax) accounting and planned-use assessment. Supervision focuses on three things: accurate measurement, reliable operation and auditable data.

Accuracy: the meter must have a valid verification basis. Every LGF-PA66 is wet-calibrated individually at the factory and ships with a verification certificate; periodic verification follows JJG 1033, the Chinese electromagnetic flowmeter verification regulation. For points tied to water-resource fee accounting, order the ±0.5%（DN50-100） accuracy class. Reliability: field intakes are harsh environments. The LGF-PA66 body is aviation-grade PA66 composite whose corrosion resistance comes from the material itself rather than a lining, so there is no rust-maintenance burden, and IP68 protection allows buried or submerged pit installation. Auditability: data must be readable remotely and leave an auditable trail. With the Hero V9 EC32 RTU the meter reports over 4G/NB-IoT, the platform automatically builds daily and monthly totals, and the full consumption curve is retained — inspectors do not need to visit the site.

Scope matters: for pressurised, always-full points such as borehole outlets and pump discharges, LGF-PA66 plus EC32 RTU is a proven combination, and off-grid sites can add solar power. Open-channel intakes cannot use an electromagnetic meter — choose a radar or ultrasonic open-channel flowmeter instead. Before retrofitting intake metering, confirm the required accuracy class and data-transmission protocol with the local water authority.
