Data Acquisition System with sensors & software included.
Tesca Concentric Heat Exchanger consists of a concentric tube exchanger in the form of “U”, mounted on a support frame. The external surface of the exchanger is insulated. Six temperature sensors are installed in both the inlet and outlet tubes, to measure the fluid temperatures accurately. To minimize losses in the system, the hot water is fed through the inner pipe, with the cooling water in the outer annulus. Control valves are incorporated in each of the two streams to regulate the flow. The flow rates are measured using independent flow meters installed in each line.
Temperature and flow readings could continuously be captured and logged into the computer with a data Acquisition System. These data are useful for further calculations and analysis. On-line trending displays allow students to observe the fluctuations of flow and temperature readings immediately. Detailed Operation & Maintenance Manual is provided along with the trainer.
