DN15-50 Brass shell with impulse Multi-jet Water Meter For Sale

Product Description

The DN15-50 multi-flow rate copper-cased water meter uses a national standard high-purity brass casing. The copper content meets standards, offering superior resistance to oxidation, rust, and water corrosion compared to iron-cased meters. It is suitable for long-term humid water supply scenarios such as municipal and commercial/residential water networks. The product employs a precise multi-flow metering structure, adhering to ISO4064 metering standards, ensuring sensitive and accurate readings and stable operation. The integrated cast-in-place design provides excellent sealing and strong pressure resistance, supporting various intelligent remote transmission upgrades.

The product features a detachable mechanism assembly, a streamlined and rational structure, convenient installation, and low maintenance costs, significantly improving subsequent operation and maintenance efficiency. The instrument's optimized fluid design provides high flow measurement capabilities while exhibiting low head loss, excellent energy efficiency, stable metering accuracy, and high sensitivity. It supports functional expansion, allowing for the addition of reed switches and Hall pulse output modules as needed. It is compatible with RS485, M-bus, NB-IoT, and other remote transmission output methods, and is compatible with both magnetic and non-magnetic sensor configurations. The entire casing is made of robust iron material, offering impact resistance, corrosion resistance, and outstanding durability, making it the preferred device for accurate metering and intelligent upgrades in small-diameter pipelines.
