Hotwell condenser level fluctuates with temperature and vacuum. When a cooling tower fan is turned on the temperature drops and the vacuum decreases and the level of the condenser on screen shows that it is maintaining a zero (0) level. However the level in the sight glass is far below the zero mark, aprox -4 to -6. We've blown out the transmitter several times and have released some air from it. Kind of new to the field, could really use a point of direction.
