temperature is only available through the serial digital interface. See
the Command Set
section.
At flows below 1 standard L/min, the temperature inside of the flow
tube will increase several degrees because of the heat generated by
the thermal flow sensor. This effect is normal and the temperature of
the incoming gas will be measured accurately once flow resumes.
Volume Measurement
These flowmeters can measure total volume by integrating flow over
time. This measurement is available only via the serial digital
interfaces. Refer to the Command Set
section for instructions on
using the volume function.
