Open Channel Flow Meter
Dynasonics iSonic 4000 - Badger Meter
An economical open channel flow meter, iSonic 4000 measures level, flow rate and total volume of water flowing through weirs and flumes. The meter includes a non-contact ultrasonic level sensor to detect the water level and then calculates the flow rate and volume using the Manning equation and characteristics of the channel. All the measurements are available over Modbus RTU and can be logged for historical records. Open channel flow meters perform best where the sediment does not build up.
