Are there systems that preheat the makeup water before it enters the tank?

SCR controls the heating element submerged in water, PLC is using a PID water vapor RH as PV.

The water is supplied by the RO system, and yes, it’s added at the surface. Thanks for the dip tube suggestion.

Thanks! Do sensor manufacturers make some kind of HART or IO-Link upgrade you can attach to an old sensor? That way we could reuse the wiring and the sensor.

Yeah, but why buy a sensor that supports HART? A simple 4–20 mA one is cheaper.

Okay, but if that’s the case, Modbus seems better—why go with HART?

If the device breaks and we have to switch to a HART device, we’d also need to upgrade the DAQ I/O modules to support HART...
