Ultrasonic Open Channel Flowmeter | Parshall Flume & Weir Transmitter | SUL815

The SUL815 Ultrasonic Open Channel Flowmeter is an all-in-one flow monitoring solution engineered specifically for municipal effluent, wastewater discharge, and environmental compliance monitoring. Designed to work seamlessly with standard primary measuring structures—including Parshall flumes, triangular (V-notch) weirs, and rectangular weirs—the SUL815 calculates instantaneous liquid flow rates and cumulative volume without touching the fluid. Featuring a wall-mounted host with a 3-inch LCD display and a remote IP65 ultrasonic sensor, it converts water head height into precise volumetric flow values (L/s up to m³/s). It is the ideal, low-maintenance choice for industrial wastewater discharge tracking and environmental reporting. Key Highlights: Flume & Weir Compatibility: Pre-configured for Parshall flumes, triangular/V-notch weirs, rectangular weirs, and custom channels. Non-Contact Level-to-Flow Calculation: Ultrasonic sound waves measure head height to calculate flow without fouling or clogging. Comprehensive Totalizer Functions: Tracks instantaneous flow rates and stores hourly, daily, monthly, and annual flow totals. Flexible Data Export: Features USB data export, MiniSD card logging, and optional micro-printer support. Industrial Signal Outputs: Standard 4-20mA analog output, RS485 Modbus communication, and up to 4 relay outputs.
