Abstract
Mass flow rate of liquid is an important parameter to be measured and controlled in a process industry. In this paper, the design of a PC based mass flow indicator has been studied using a well known temperature sensing IC AD590. The temperature sensing IC AD590 has been used as a flow sensing element and the effect of fluid temperature has been eliminated by using four identical IC units. Four IC units are connected in the differential mode. The output of the differential circuit is sent to opto-isolator circuit through a signal conditioner circuit. LabTech Notebook Pro software has been used for the flow rate display on a PC monitor. The output of this circuit has been theoretically related with flow rate of the fluid. Experiments have been performed to find the operational characteristics of the transducer. In this paper, the experimental results are presented, a good performance characteristic has been observed.
