A water flow meter can be used to measure the heat recovery of a compressed air system by measuring the flow rate of the water used to cool the compressed air. The heat generated by the compression process can be recovered by passing the compressed air through a heat exchanger, where it transfer heat to the water.
By measuring the flow rate of the water before and after it passes through the heat exchanger, the amount of heat transferred from the compressed air to the water can be calculated. This can provide information on the efficiency of the heat recovery system and identify any potential issues.
