A flow data logger is a device used to measure and record the flow rate of a fluid in a machine. This information can be used to monitor machine performance, troubleshoot problems, and improve performance. There are a few different ways to use Flow Data Logger on a computer. One way is to place the locker directly in the flow. This will give you a more accurate measurement of the flow rate but is more invasive. Another way to use a flow data logger is to place it downstream of the machine. This will give you a less accurate measurement, but it will be less invasive.
