    • A chiller system including an evaporator for evaporating a refrigerant and a water pipe in fluid communication with the evaporator. The water pipe is configured to allow water to pass through at a flow rate and to circulate the water with the evaporator to exchange heat with the refrigerant in the evaporator. The chiller system includes a flow restrictor tube within the water pipe that is configured to allow the water to flow through the flow restrictor tube at a reduced flow rate relative to the flow rate. The chiller system also includes a measuring probe that passes through walls of the water pipe and the flow restrictor tube and includes an accuracy range of flow rates less than the flow rate. The measuring probe is configured to measure the reduced flow rate within the flow restrictor tube where the reduced flow rate is within the accuracy range.
    • 一种冷却器系统,包括用于蒸发制冷剂的蒸发器和与蒸发器流体连通的水管。 水管构造成允许水以流速通过并且使水与蒸发器循环以与蒸发器中的制冷剂交换热量。 所述冷却器系统包括在所述水管内的限流管,所述限流管配置成允许水以相对于所述流速的降低的流速流过所述限流管。 冷却器系统还包括通过水管和限流管的壁的测量探头,并且包括小于流量的流量的精度范围。 测量探头被配置为测量限流器管内的减小的流量,其中减小的流量在精度范围内。
