Flow rate time unit Per second Per hour Per day
For volumetric flow rates, the unit is determined by all of the above settings. For example, if the metric units system, m
3
volume, and "per hour" volumetric flow rate time unit are
selected, then the volumetric flow rates are read in m

/hr.
Note: Digital outputs 1A and 1B share a common ground with Frequency outputs 1A and 1B. Digital outputs 2A and 2B share a common ground with Frequency outputs 2A and 2B.
When connecting the ultrasonic meter to two different devices, it is recommended to connect Frequency outputs 1A and 1B and Digital outputs 1A and 1B to one device and
Frequency outputs 2A and 2B and Digital outputs 2A and 2B to the other device. This will prevent ground loops.
