1. An apparatus for monitoring a cooling system comprising a chiller and a heat exchange process connected to the chiller by a coolant supply line and by a coolant return line, the apparatus comprising:
a first temperature sensor, for measuring a coolant temperature in the coolant supply line;
a second temperature sensor, for measuring a coolant temperature in the coolant return line; and
a readout circuit, for monitoring respective temperatures sensed by the first temperature sensor and the second temperature sensor,
wherein:
the coolant return line is configured to carry coolant from the heat exchange process to the chiller,
the readout circuit comprises a processing circuit configured to:
perform a first temperature sensing operation with the first temperature sensor, during an interval of time;
perform a second temperature sensing operation with the second temperature sensor, during the interval of time; and
display, on a display, a first temperature value and a second temperature value, and
the first temperature value is a difference between a temperature measured in the first temperature sensing operation, and a temperature measured in the second temperature sensing operation.
