The Micro Motion straight-tube Coriolis sensor has two separate temperature measurement circuits.
The first temperature measurement circuit consists of one RTD directly connected to the flow tube, which measures the temperature of the process fluid through the flow tube.
The second temperature measurement circuit consists of three RTDs: two on the reference tube and one on the case. These three RTDs are used to compensate for differences in temperature between the case, reference tube, and the flow tube.
This Micro Motion measurement circuit provides accurate flow and density measurement under varying thermal conditions.
