Ultrasonic Open Channel Flow Meter

TUF-MOCF

The TUF-MOCF Ultrasonic Open Channel Flow Meter is designed for accurate flow measurement in open channels such as flumes, weirs, and wastewater streams. The system uses ultrasonic pulse echo technology to measure the liquid level in the channel and calculate the flow rate based on the channel geometry. With smart echo processing, automatic temperature compensation, and robust probe construction, the TUF-MOCF ensures reliable performance in water treatment, environmental monitoring, and industrial discharge applications.

Frequently Asked Questions About This Product

An open channel flow meter is used to measure liquid flow in channels where the fluid is not confined inside a pressurized pipe, such as rivers, drainage channels, and wastewater treatment plants.

The sensor sends ultrasonic pulses toward the liquid surface and measures the time taken for the echo to return. This determines the liquid level, which is then used to calculate flow based on channel geometry.

They are widely used in water treatment plants, wastewater treatment facilities, environmental monitoring systems, and irrigation channels.

The meter supports 4–20 mA output with optional HART and MODBUS communication for integration with industrial control systems.

The ultrasonic sensor supports level measurement ranges up to 40 meters, depending on the selected configuration.
