Control products can be subjected to harsh environments where they can be splashed during the process or covered in dust or get warm through their location. The E5CN, E5CSV, H7CX, H5CX and K3HB all feature a NEMA4X (IP66 equivalent) front panels so are suitable for the use in these applications, also the low profile fascia means that they are less prominent in the front of the panel and so less likely to become dirty.

Monitoring the flow rate of the two liquids means that if one changes the other will match the change, with the offset required helping to maintain product quality. The colour change display can be used to identify when the rate changes and additional alarm points can be set to give local or remote outputs. A linear output could be used for an input into a PLC system, SCADA or chart recorder if external monitoring or traceability are required.

A linear output flow sensor is used in the pipe to measure the flowrate through the tube, the K3HB-X is used as a local display. This can be the first indication of potential problems within the system, a leak would cause the flow rate to increase as the liquid is lost a blockage would cause a decrease in flow rate.
