System for Oil Refinery Parameters Measurements Based on Piezoresistive and
Strain Gauge Pressure Sensors
Iman Morsi, Loay Mohy El Din Rasheed
Abstract
A
typical oil refinery has a number of physical parameters that need to be
measured, including pressure, flow rate and level. Authors built a
microcontroller system based on PIC 16F877A, piezoresistive differential
pressure DP sensor (24PC series) and strain gauge DP sensor (IDP-10) with
ranges from 0 to 15psi.
The results of the microcontroller system revealed the following:
the percentage error for piezoresistive sensor in pressure from 0.43808% to
8.613 %, in flow rate from 0.21929% to 20.340%, and in level from 0.43808% to
2.5789%. The percentage error for strain gauge sensor from 0.846% to 1.946% for
pressure measurement, from 0.1% to 0.4% for flow rate measurement and from 0%
to 0.64% for level measurement. The percentage error of the piezoresistive
sensor is more than the percentage error of the strain gauge sensor: for
pressure measurement by about 6.667%, for flow rate measurement by about 19.94%
and for level measurement by about 1.9389%. Fuzzy logic is used to predict the
output surface of pressure, flow rate, and level measurements.
