Flow Measurement
/Method Conversion from surface velocity measurement to average velocity based on patent pending self- learning model using velocity distribution measurements
Conversion of water level and pipe size to fluid area/ultiplication of fluid area by average velocity to obtain the flow rate
Conversion Accuracy +5% of reading
Assumes pipe is 0 to 90% full
Communication
RS-d85 communications port with Modbus ASCII slave communication protocol
