Method for determining volume and mass flow through power main, involves maintaining constant difference in pressure over valve body such that automatic controller action is reached to make valve authority equal to specific percent
Method for determining volume and mass flow through power main, involves maintaining constant difference in pressure over valve body such that automatic controller action is reached to make valve authority equal to specific percent
The method involves evaluating stroke value of a pressure independent control valve. Constant difference in pressure is maintained over a valve body such that an automatic controller action is reached to make a valve authority equal to 100 percent. Return temperature measurement of an associated fluid-flowed through consumer is measured such that heating and/or a cooling performance is enabled. The pressure independent control valve is combined with a microcontroller over a display. An independent claim is also included for a device for determining volume and mass flow through power main.
