A system is provided with an ultrasonic flow meter. The TCP parameters may be selected before usage or at start-up such that a TCP connection is dynamically configuredre-configured prior to transporting the traffic flow over the network. The polarizer includes a first transparent conductive layer, an upper polarizing layer, and a second transparent conductive layer on the second surface of the upper polarizing layer stacked together. During a heat-up operation of the valve, current is applied to only one of the coils so that the reduced resistance of a single coil provides increased heat.
