9.5 P4 – LOW FLOW CUTOFF
This register is used by the gauge to set a minimum active displayable flow value. Once the flow measurement falls
below this value the LCD on the front panel and the serial port will show zero flow. This will allow the user to set a
low flow threshold so that erroneous or noisy data at the low end of the measurement element will not be displayed
by the gauge. A typical setting value for this register might be 0.0 to prevent system noise from causing negative
flow measurements from being displayed.
The decimal point is used to indicate the status of the Low Flow CutOff detection. When the unit is in the measure
mode of operation and the flow rate falls below the Low Flow CutOff value. The display will show zero with a
flashing decimal point.
