The principle of the Liquids Mixture Control System By using PLC is to mix two
or more types of liquids with different PH values, in order to acquire new PH
value with correct composition, which to maintain product quality .These
processes exist in beverage, drinkingwater, food, pharmaceuticals, chemistry,
refinery indutries, also important for fish hatcheries, water conditioning and
aquaculture, etc, moreover correct composition of PH value in our diet is
important for our health,therefore for this project, volumetric of one type of
liquid,can be determined its quantity of volume before entering into the Mixture
tank and then, another liquid is entered automatically into this Mixture Tank,after
that the mixing process will be done,which this system determined PH value
automatically that macthing the PH value requirement as a complete
product.Programmable Logic Controller (PLC) with analogue input signal is used
to control this Liquids Mixture Control system.This system consist of six tanks,
with one mixturer motor and also five pumps are used to control the system via
PLC. PH sensor is used to detect PH value of the mixture, which this signal is fed
to analogue input PLC teminal, that to be used for comparing PH value required
as a product. The user can select volume one type of liquid to be entered into
Mixture Tank, by pressing select buttons on the control panel board.This project
can be used for manufacturing industries base on liquids and also for fish
hatcheries, water conditioning and aquaculture ,which have been proved by
project analyzing and testing results
