ABOUT 3077-755A 9907-147N 5501-303L :

The flow element consists of two pairs of thermowells of the same size, shape and mass. One pair contains a platinum RTD and a heater element. The other pair contains one RTD. The RTD located next to the heater element is called the active RTD. The other RTD is referred to as the reference RTD. Since the active RTD is adjacent to the heater, the temperature at the walls of the thermowell are always above the temperature of the process media. The temperature at the reference RTD is the temperature of the process media. When the process media is flowing past the active RTD a quantity of heat is carried off into the flow stream. The amount of heat taken from the active RTD is a function of the process media mass flow rate. A ∆T exists between the two pairs of thermowells and a proportional ∆R exists between the active and the reference RTDs. The ∆R is measured by the flow transmitter. The relationship of ∆T to the mass flow rate is calculated by the flow transmitter and is converted into a signal or is sent to the flow transmitter's display.
