South Africa’s municipal water infrastructure is undergoing a critical transformation. With aging networks, water scarcity, and the urgent need to reduce Non-Revenue Water (NRW), municipalities need modern metering solutions that deliver accuracy, durability, and smart capabilities.
El Tengyue plastic-body ultrasonic water meter addresses these challenges through three core advantages tailored for South African municipal applications.
Lightweight, Corrosion-Resistant Design
The Challenge: Traditional brass meters face corrosion from aggressive water quality and rampant theft for scrap metal value.
La solución: Our plastic-body meter uses high-grade engineering polymers that withstand pH levels from 4 to 12, far exceeding typical municipal water ranges . The lightweight design (70% lighter than brass) reduces installation labor costs by 15-20% . More importantly, the polymer construction eliminates scrap value, stopping meter theft—a persistent issue in South African municipal projects .
Long-Life Reliability with No Moving Parts
The Challenge: Mechanical meters experience wear and accuracy degradation, requiring frequent replacements.
La solución: Ultrasonic technology eliminates moving parts entirely. The solid-state design delivers 16-20 years service life compared to 8-10 years for mechanical meters . With Protección IP68, the meter remains fully operational even when submerged during floods . The corrosion-resistant polymer body, tested to 4800 kPa, withstands pressure surges without degrading .
Precision Measurement & Smart Connectivity
The Challenge: Low-flow leaks go undetected by mechanical meters, contributing to South Africa’s NRW problem.
La solución: Ultrasonic measurement captures flows down to 2-3 liters per hour , detecting hidden leaks that mechanical meters miss. The meter supports real-time AMI/AMR connectivity (NB-IoT, LoRaWAN, wireless M-Bus), enabling instant leak alerts, tamper notifications, and remote reading—reducing NRW by 12-18% in municipal deployments .
