Application Cautions for Insertion Flowmeters
Understand that, unlike a full-bore flowmeter, insertion flowmeters do not measure the flow in the entire pipe --- they infer the flow in the entire pipe from a small number of measurements. Hydraulic and other measurement issues can result in large measurement errors.

Be sure that adequate straight piping is installed upstream to condition the flow so that the flow at the point of measurement represents the average, center-line, or proprietary flow that was used for calibration purposes. Locate the sensor properly so as to measure at the correct location, because failure to do so directly affects measurement accuracy. Make provisions to remove the flowmeter, such as installing a valve and sealing arrangement when the pipe cannot be taken out of service.
