Ultrasonic Water Meter S-UWM

Water Meter S-UWM

Introduction
S-UWM is a smart water meter based on the latest ultrasonic technology. The meter has no moving parts and maintains its pinpoint accuracy throughout its entire lifetime of up to 15 years.
The meter has industry-leading low flow accuracy to ensure that even very low flows are measured down to the very last drop. This secures a fair and correct billing, improves the quality of your data and helps you to reduce Non-Revenue Water.

Features and Benefits

  • High Accuracy
    The S-UWM ultrasonic water meter has a low start flow down to 0.002m3/H which ensures that
    even very low flows are measured.
  • Alarm function for Leakage & Burst
  • Intelligent Design
    The S-UWM is made from 100% Eco-friendly and durable composite. The upper cover is 6mm
    thick tempered glass, the shell cover is 2.5mm thick. It is anti-ultraviolet, anti-aging, strong
    weather resistance.
  • Measuring Excessive Consumption & Wasting Water
  • Long lifetime
    The S-UWM Ultrasonic Water Meter is fitted with 4 lithium batteries with capacity 14400mAh.
    Depending on use and setup, the lifetime is up to 15 years.
  • Little Maintenance
    In general, it is no need maintain after installment
  • Communication
    The S-UWM Ultrasonic Water Meter supports remote reading through the following
