A relative-reading flow monitor with a built-in learn function, the Pro-50 does not have any moving parts and is constructed of stainless steel. When the user turns on the flow, the unit automatically scales itself to display that rate as 100 percent full flow. The process setpoint then is automatically set at 50 percent without requiring calibration or adjustments. Setting can be changed via pushbutton. The unit meets IP67 protection standards and offers epoxy-encapsulated electronics for shock and vibration. It is capable of low-flow monitoring.
