HONEYWELL PID module PV value change rate
Thread Content
May I ask what parameter in the HONEYWELL PKS300 PID module represents the rate of change of the PV value? I need to implement a function that converts a decrease in liquid level into a flow rate value
There is a way to do this, namely by using calculation methods alone; an auxiliary calculation module can be employed, and by configuring the appropriate formulas within that module, the result can be obtained.
I remember that in the Yokogawa system, there is a parameter called VL which represents the rate of change. What formula should be used in the calculation module? The decrease over a certain period divided by time? How is this time determined in the formula? Please make it explicit as well
