bytes 6-9: (32 bit long integer, MSB first) totalizer for TOTAL volume + or batch quantity ( batch quantity
only for ML M3F )
bytes 10-13: (32 bit long integer, MSB first) totalizer for TOTAL volume - or batch quantity ( data valid
only for ML 210 )
bytes 14-15: (16 bit unsigned integer, MSB first) process flags:
bit 0 =1 if the excitation is too fast for the sensor connected
bit 1 =1 if the maximum alarm is active
bit 2 =1 if the minimum alarm is active
bit 3 =1 if the Flow rate exceeds the scale range value (overflow)
bit 4 =1 if one or more output impulses are saturated (too many impulses to emit)
bit 5 =1 if the measurement signal is highly disturbed or if the sensor is disconnected
bit 6 =1 if the measurement tube is empty
bit 7 =1 if the circuit powering the coils is not working or the sensor is disconnected
bit 8 =1 if the second measurement scale is active
bit 9 =1 if the Flow rate is lower than the cut-off threshold
bit10=1 if the Flow rate is negative
bit11=1 if a new measurement value calculated for the display is available
bit12=1 if the counter block signal is active
bit13=1 if dosing is in progress
bit14=1 if a calibration cycle is in progress
bit15=1 if a Flow rate simulation is in progress
