Reading configuration parameter of device when applying Formula

Reading configuration parameter of device when applying Formula

Hello, 

Is there a way to read a configuration parameter of a device to calculate a formula on a widget?

For e.g. if I have a blueprint dashboard and I have to calculate the volume of water in a tank but each device has a different height(which is stored in the configuration parameter of each device). Can I retrieve this height so as to alter the formula for each device?
