The D430S Weir and Flume Flow Collector is a data acquisition device specifically designed for critical monitoring fields such as hydrology, water conservancy, and environmental protection. It supports data collection from various sensors via common communication interfaces such as RS485, RS232, and 4–20mA. The device also performs flow calculation and accumulation. By connecting an external liquid level sensor and utilizing its built-in standard weir-flume models, it calculates instantaneous flow rates and total accumulated flow, providing robust data support for flow monitoring tasks.

Equipped with a 4.3-inch high-definition screen, the collector enables users to conveniently query real-time sensor data, monitor current statuses, flexibly configure system parameters for personalized needs across scenarios, precisely adjust sensor settings, and perform on-site sensor debugging to enhance operational efficiency. For data interaction, the device supports the standard Modbus protocol. External PLCs, RTUs, or other data acquisition and transmission equipment can easily access the collector’s acquired and computed results through its RS485 interface.
