FLUID METERING FOR PERISTALTIC PUMPING

Y. Feng, C. M. Jiang, W. H. Deng
Abstract:
Peristaltic pumping is a common process in chemical, biomedical and pharmaceutical applications. However, the actual measured flow is frequently found to be erroneous with an accuracy no better than 10%. In this paper we present a design of the precise fluid metering sensing technology using MEMS thermal time-of-flight principle in a close loop with the peristaltic pumping for the bio-fluidic analyser. The data indicate that the MEMS fluidic meter could significantly improve the accuracy and control of the fluid delivery within 5% which not only substantially reduces the cost but boosts the performance of the instrument by better controlling the sample to carrier liquid injections.
