Open Channel Flow Meter, a versatile and intelligent solution for measuring both liquid level and flow rate in open flow applications.

 

Unlike traditional flow meters designed for closed pipes, Philemon‘s open channel flow meter is tailored for free surface flow environments, such as Parshall flumes, V-notch weirs, rectangular weirs, and irrigation or drainage channels. Utilizing ultrasonic or radar level sensing technology, the device accurately detects water level changes and automatically calculates the corresponding flow rate based on the geometry of the flow structure.

 

This dual-function instrument offers non-contact, maintenance-free operation, making it ideal for:

 

Municipal water monitoring

 

Wastewater treatment

 

Irrigation and hydrology

 

Industrial discharge supervision

 

With a user-friendly display, multi-language interface, and built-in flow algorithms for various flume types, Philemon’s open channel flow meter greatly simplifies on-site setup and data integration. Output options such as 4–20mA, RS485, and Modbus allow seamless connection with SCADA systems and remote monitoring platforms.

 

Designed to withstand harsh outdoor environments, the instrument comes with IP65/IP68 protection, high-temperature resistance, and stable performance in varying weather and flow conditions.
