Flow proportional constant volume, variable time (CVVT)
CVVT sampling is a flow-proportional method of sampling. CVVT samples are taken
when a user-defined flow volume occurs in the flow stream. This occurs when the
sampler is programmed to take a sample every time a specified volume of flow occurs in
the flow stream. Specified flow volume intervals can vary with the flow rate of the stream,
therefore varied time intervals can occur when constant (fixed) volume occurs.
Flow volume is determined internally, by the optional integral flow meter or by an external
flow meter.
