This research performs thermal analysis of the central heating's radiator by the final
elements method manner using Cosmos/m2.6, Where it was designing a three dimensional
model of the radiator with engineering specifications that mimic one of the
used radiators
.Then apply a convection simulates the role of the mediator heating used and ambient
temperature for concluding the mathematical behavior of thermal gradient within the
radiator.
Research proposing a control system depends on adjusting the intermediary of
heating inside the radiator, through the installation of flow control valve which works by
D.C motors at the entrance to each radiant.
The research shows the inability of depending on controlling system which uses the
PI controller in building a suitable control system, Because the difficulty of receiving
signals from analog temperature sensor that reflect the constant readings of room
temperature which makes the response of control valve for signals slow, Thus makes the
use of PI unhelpful of the economic and technical side.
This paper discusses improveming of the methods of computerized measurements by using some practical examples in the field of automation of flow, and pressure and level measurements and data
logging. Tnis work has been done on an experimental station, which has been developed specifically for this paipose. It is a multi purpose station for training on automation of measuring techniques in
industrial processes
