PRO-50 Flow Switch with Flow Trend Display

The new captor P-R-O 50 Flow Switch is for applications requiring RELATIVE measurement and set-point of flow rate. This means that the actual velocity of the flow or the quantitative measurement in GPM is not known and is not important. What is important is that the Flow Switch set-point can be set as a “percentage of” or “relative to” the full flow rate. No other flow switch could do it this simply or effectively.
