Open Channel Ultrasonic Level Meter

0.3m to 1m. The output will be directly the instantaneous flow rate. Meanwhile, the flow range can be up to 10000 liters per second, and it is up to the size of parshall flumes and your requirement. The accumulative flow will be displayed and stored for a long time.

In addition, our open channel ultrasonic level meter has an error rate of 5%, in which 1~3% due to the uncertainty from Parshall flume slot allocation, and 1~2% due to the instrument error.
