Reliable flow measurement in open channels

Wastewater flow measurement in open channels faces multiple challenges: fluctuating hydraulic conditions, backwater effects, and environmental influences such as foam, turbulence, and debris. Traditional systems often lack flexibility for different channel types and struggle with accurate compensation when downstream restrictions occur. Additionally, integrating reliable signals for samplers and plant control systems can be complex, especially when multiple measurement points are required. These issues demand a robust, adaptable solution that ensures precision, easy configuration, and dependable performance under harsh conditions.

FlexView FMA90 is a versatile control unit for radar, ultrasonic, hydrostatic, HART or universal 4–20 mA level sensors. It offers precise flow calculation in open channels, weirs, and pipes, with easy selection of predefined flumes and integrated Q/H tables for quick configuration. The device supports two independent flow calculations and totalizers in one unit, making it ideal for multi-point monitoring. Advanced backwater detection and compensation using a second level sensor ensures high accuracy even under challenging conditions. Available in field, DIN rail, and panel housing variants, FlexView FMA90 guarantees seamless installation and reliable operation in wastewater plants.
