The liquid level in a tank is controlled using a Pneumatic proportional

The liquid level in a tank is controlled using a Pneumatic proportional controller as shown the figure below. The level sensor is able to measure over the range 1.85 to 2.25 m. it is found that, after adjustment, the controller output pressure changes by 4 kN/m for a 0.01 m variation in liquid level with the desired value held constant. If a variation in output pressure of 80 kN/m moves the control valve from fully open to fully closed, determine the gain and the proportional band.
