Product Details
Dry dial multi jet water meter, valve control for prepaid RF IC
DN15 - DN25
It's developed to help control the water use via electronic
controlled ball valve. The prepaid water meter is completely
designed according to STS (Standard Transfer Specification) and
able to measure in high accuracy. The step-tariff and fixed-tariff
can be set.
