1. Introduction
Control is an important aspect in the production process since it gives the desired output with the
given input parameters. For decades, this discipline has seen the increase in the production
efficiency by reducing unnecessary costs for certain activity. In the process depicted in the
diagram in the question, several control loops are present to ensure that the light amount sugar,
coffee, milk, temperature and water are in place (Brando, n.d.). The process is more complex
that it appears to since extensive mathematical calculations and modeling is need in every stage
of production. Since it is an automatic process, very little input from human hands is necessary
once the process starts. among the many advantages that come along with automation is the
consistency of quality of the goods produced. For instance, the person served first by the
machine and the one served last will have their coffee with same sugar concentration, coffee
concentration and at the same temperature (Brody, 2009). Also, water boiled in the boiler will
consistently be at the same temperature regardless of the amount needed. Since this machine is
common in coffee shops, there are pick hours when there are several people and there are times
when there are few customers. the amount of water needed when there are a lot of people is
quite high and therefore the system has to heat up to keep up with the demand while maintaining
quality. Using the control and instrumentation the heat of furnace is either increased or reduced
depending on the amount of water needed. Though there have been numerous advantages
attributed to the automation, several people whose skills were limited to manual laboring were

rendered jobless. However, there are several other opportunities that open such as the in factories
where sensors and other control gadgets are made.
2. Process requirement
Without any doubt there are several instruments for measurement and control that this process
requires for it to work efficiently. Among the are the flow sensors, temperature sensors, display
system, alarm system, flow control among many others. in this report, every activity of
production will be analyzed individually. among the requirements are the instruments, sensors,
pumps, pipes, lagging materials among many others (Choubey, 2017).
1. Level mearing sensors
The levels of water and milk has to remain at a certain level. This is dependent on accurate
measurement to ensure the process control is reliable. The sensors plays important role in
ensuring that there is no overflow of milk tanks and water tanks as well. Another function of the
sensors is to ensure that the tanks do not go dry (Environmental Conundrums of Coffee
Processing, 2017). Dry tanks may cause the pumps to run dry which is not a very good thing for
the pumps. In the water system, the sensors are located water reserve, water tank and the boiler.
In the milk system, the sensors are needed in the milk reserve and the tank as well. The coffee
and sugar contain also have the level sensors. The precise measure from the sensors ensure that
checking and balancing of raw materials, finished and semi-finished product is adequately
performed. Therefore, these sensors are important in inventory keeping, retracing and
demarcation of each and every batch. The reliability of the level sensors is heavily depended
upon by the production planning process and all the logistic supporting the process. Such
instruments may include the echomax transducer, ultrasonic technology and sitrans.
