Abstract
This report describes the development of a Microcontroller based product that monitors and controls the foam that is produced in Industrial processes such as Brewing, Pharmaceuticals, Food, Effluent Treatment etc. The project was carried out by Charis Technology Ltd. , a British SME with 4 employees, of which one is an electronic engineer and one is a technician.

The aim was to develop a new product using a microcontroller to replace a previous product that used conventional analogue and digital circuitry. The new product is a programmable device with greater functionality, e.g. self-calibration, multi-dimensional measurements and serial communications. The microcontroller used is a PIC16C74, 8-bit device, with built-in A/D converter. The software was written in the "C” language which proved to be suitable for the whole project.

The first user had no previous experience of microcontrollers and how to use them. The project took 12 months to complete, which was 3 months longer than the original plan. The over-run was due to an underestimate of the effect of the project on the other operations of the business. The project cost 49K Euro to complete, the payback time is approximately 18 months and the expected return over the product lifetime of 5 years is 400K Euro.

The application experiment will be of interest to any small company working in instrumentation and considering a move to the adoption of Microcontroller technology.
