Product Description

Product Introduction:

Applicable Area:

It is suitable for residential area and meter improvement, it can satisfy the accurate metering from the water supply company.

Features:

It can keep the historical data for a long time, and it has diversified alarms.
High accurate metering, we can customize R400, R500 and R800.

Technical Strength:

It is no need to enter in to the verification mode for all meters, it can ensure the metrological mode are same between filed and calibration station.
High freezing resistance under the self-innovated temperature compensation module.
Wide range ratio which is up to 800：1, it can satisfy the accurate metering on light flowrate.
