Open Channel Ultrasonic Flow Meter

Product Description

The Open Channel Ultrasonic Flow Meter from Brotek Instruments is a high-precision, non-contact flow measurement solution designed for continuous monitoring of liquids flowing through open channels, rivers, canals, flumes, weirs, and partially filled pipes. It operates by transmitting ultrasonic pulses toward the liquid surface and measuring the echo return time to determine the liquid level. Using pre-programmed hydraulic equations and channel dimensions, the instrument automatically converts level measurements into accurate flow rate values without contacting the process medium. The flow meter features automatic temperature compensation, intelligent signal processing, and support for all standard weirs and flumes, ensuring dependable performance under varying environmental conditions. With no moving parts, the system requires minimal maintenance while providing excellent long-term reliability in corrosive, humid, and outdoor installations. Its robust IP66 transmitter and IP68 ultrasonic sensor make it suitable for permanent field installations, while the LCD display offers clear visualization of flow rate, liquid level, and system status. The instrument supports 4–20 mA analog output, RS485, and Modbus communication, allowing seamless integration with PLC, DCS, SCADA, and remote monitoring systems. It is widely used in wastewater treatment plants, irrigation canals, stormwater drainage systems, municipal water distribution, hydropower stations, industrial effluent monitoring, environmental monitoring, and mining applications, providing reliable and maintenance-free flow measurement for open channel systems.
