Fluid Dispenser Prototype: A Time Based Approach

Abstract

In today's era when precise, accurate and time efficient systems are in great demand, automated techniques
supersede manual practices. As a need of time, we introduce a wireless, automated, cost effective, yet reliable and efficient system of fluid dispensing. Our prototype system can dispense varying amounts of fluids in milliliters (maximum 1L) as per demand of the user. It uses the principle of time based fluid dispensing achieved through the built-in timer property of the AT89C51 microcontroller. To satisfy the principle used and verify the system's accuracy, fluids of varying viscosities were dispensed and monitored. The experimental results of the wireless fluid dispensing system when tested showed linear relationship between the dispensing time and desired volumes of fluids having differing viscosities. The added feature of wireless control using HM-TRP series transceiver module along with onsite control via a keypad eliminated the need of physical presence of operator within the range of 10 meters in order to make the system operational. This system can be used in pharmaceutical and beverage industries as well as in different laboratories for dispensing and filling volumes of fluids with varying viscosities.
