Surry Power Station has Cameron UFMs installed at our plant and were wondering if any other sites have seen ambient temperature changes cause UFM Transducers to decouple (i.e. gains increase and Signal to Noise ratio decrease). The temperature change seen at Surry was approximately 30 degrees in 20 minutes.
