Set value - Return to set value

2009-03-23View Original

Thread Content

When the measured liquid level is higher than the set value, the opening degree of the control valve is reduced, which decreases the feed rate and thus lowers the liquid level back to the set value. Translation: ..........in order to make the liquid level return to the set point. Is \"return to\" appropriate?

When the measured liquid level is higher than the set value, the opening degree of the control valve is reduced, thereby decreasing the feed rate and lowering the liquid level back to the set value. When the measured liquid level is above the set-point, adjust the control value to reduce (material) loading until the liquid level drops to the set-point.

When the measured liquid level is higher than the set value, the opening degree of the control valve is reduced, thereby decreasing the feed rate and lowering the liquid level back to the set value. My attempt: When the measured level is above the set point, reduce the feeding rate by throttling the valve opening so as to lower the level back to the set point.
