Large-Diameter Ultrasonic Heat Meter DN200

Overview

Large-diameter ultrasonic heat meters are high-technology devices designed to measure thermal energy in liquid or steam lines. Using ultrasonic measurement technology, they determine the fluid velocity and calculate the consumed energy from the temperature difference between the inlet and outlet lines. They are indispensable for district heating systems, industrial production facilities and central energy management projects.

Key Features

• 🔬 High-Precision Measurement: With picosecond (ps) level high-precision chips and platinum (PT1000) thermal resistors, it measures accurately even at the lowest flow rates.
• 💳 Flexible Payment and Billing: Supports prepaid, per-meter prepaid or mixed billing models via the platform. Fully compatible with WeChat, Alipay and mobile apps.
• 📊 Comprehensive Data Storage: Records total heat, cooling, flow and operating-time data in hourly, daily and monthly periods. Data is securely retained for a long time even during power outages.
• 🚨 Smart Monitoring and Safety: Equipped with real-time monitoring features such as empty-pipe alarm, low-battery warning, temperature anomalies and sensor fault detection.
• 🔋 Ultra-Low Power Consumption: Thanks to its built-in high-capacity lithium battery and low-power design, it offers a battery life of over 6 years.
• 🛠️ Easy Installation: Can be mounted horizontally or vertically as needed; can be installed on the inlet or return line.
• 🌐 Remote Update (OTA): All software updates can be performed remotely (online) without removing the device or physical contact.
• 🔌 Broad Communication Infrastructure: Easily integrates into any automation system with modern communication protocols such as M-BUS, RS485, LoRa, LoRaWAN, NB-IoT and Cat.1.
