Introduction

An RF card water meter is a smart water meter that uses radio frequency (RF) technology for wireless data transmission. It enables remote monitoring of water usage, prepaid or postpaid billing, and supports contactless recharging via an RF card. This technology improves accuracy, convenience, and efficiency in water management for residential, commercial, and industrial applications.

Features

1.Mechanical and electrical separation facilitates installation and maintenance

2.The liquid crystal display is synchronized with the mechanical part

3.Timing of valve rotation ensures flexibility

4.Applicable to low-density meter metering scenarios
