PC based measurement and control are important to the industrial automation. The signal transmission through a hazardous region in the form of optical signal is preferred more than the electrical signal. In the present work, an experimental study has been made with low cost modified optically isolated Rotameter based flow transmitter and flow control system. This flow indicating controller has been designed using modified LVDT based Rotameter, PC based controller NI DAQ and LabVIEW software. An analog signal-conditioning and flow control circuit is developed. The same was calibrated with flow measuring test rig with a standard available industrial flow meter. The output of the opto-isolator circuit has been shown in a PC and the flow rate is controlled to a desired value using LabVIEW software. The output of the Rotameter is sent to the remote location through optical fiber cable and converted to electrical signal using optoelectronics converter. The experiment has been performed and results are presented in the paper. The experimental result follows the theoretical equations. Simulation is done on optical flow transmitter. It has been observed that variation of LVDT output voltage and the characteristic of the transducer and PC based controller are all linear in nature. © 2017 IEEE.

Design and implementation of a real time PC based flow indicating controller and optical transmitter

The ordinary orifice transducer widely used in process industries for flow rate measurement produces a differential pressure which is generally measured by a DP cell and thus may suffer from various problems like leakage of process fluid, corrosion of diaphragm materials, etc. In this paper, the design of a noncontact capacitance-type orifice transducer for the measurement of flow rate of a conducting liquid through a pipeline has been described. In the proposed transducer, the use of a diaphragm-type DP cell is not needed, and thus, the problems associated with DP cell are avoided. The theoretical analysis of the flow transducer is presented in this paper. The performance of the flow transducer along with that of the signal conditioner for flow of tap water through a pipeline has been tested experimentally. The experimental results are presented in this paper. A good linearity and repeatability of the sensor capacitance, transducer output, and signal conditioner output with flow rate have been observed. © 1963-2012 IEEE.
