Abstract: |
The paper presents the design and
experimental experience with the gas flow measurement instrument for the
range of (5 – 25) ml/hr. The aimed application area is in a biochemical
laboratory for the study of reaction kinetic of sediments decomposition in waste water. The time – of – flight type of sensor with
one upstream and one downstream temperature sensor has been chosen for the
study. We explain the basic operation principles of the tiny flow measurement
and the sensor structure. In the numerical model paragraph, we are describing
the basic configuration model and the modelling
results. As the three – dimensional simulation would be very time consuming
process, we have simplified the simulation for only two – dimensional task.
The presented diagrams are derived for different gases (air, nitrogen, carbon
oxide and chlorine) and sensor tube materials, namely steel, copper, and plexi-glass. We present also the experimental set – up
including the design and sensor parameters. The paragraph with experimental
results and discussion on them illustrates the good correspondence with
expected values. The paper concludes with the employment of designed gas flowmeter in the biochemical laboratory. |
