Microprocessor based water level controller

Microprocessor based pee take aim get windlerMicroprocessorThe processor is the portion of a calculating machine system that carries out the instructions of a computer program and is the primary comp 1nt carrying out the computers function. The form, design and implementation of CPUs have changed but their fundamental operation remains the same. The littleprocessor contains all the central processing whole (CPU) functions and is the engine that goes into motion when you turn your computer on. The microprocessor is designed to perform arithmetic and logic operations that make use of small number holding atomic number 18as called registers.The plat of microprocessor is given as underAlso microprocessor is a multipurpose, programmable, clock-driven, register based electronic device that reads binary instructions from a storage device called memory, accepts binary data as stimulant drug and processes data according to those instructions and provides as output. A microprocessor i ncorporates realisticly or all of the functions of a central processing unit (CPU) on a single integrated circumference (IC). The first microprocessors emerged in the early 1970s and were used for electronic calculators, using binary-coded decimal arithmetic on 4-bit words. Other embedded uses of 4- and 8-bit microprocessors, such as terminals, printers, various kinds of automation etc, followed rather quickly. Affordable 8-bit microprocessors with 16-bit addressing also led to the first common purpose microcomputers in the mid-1970s.The most reliable circuit is piddle take Controller circuit which takes the task of indicating and Controlling the water train in the overhead water tanks. The LED forbid graph is used for displaying the water level.The water level is sensed with the help of copper analyses. The probes which have to be monitored are inserted into the water tank.This water-level Controller circuit is set up around the well-kn give 8 bit Microprocessor 8085. It straightly monitors the overhead water level and display it and also switch off the motor when the tank fills and it go away mechanically switch On the Motor when the water level is low. The Microprocessor result also indicate the water level over the LED display.All the input and output functions are done through the Programmable Peripheral Interface IC 8255.Product Categories for water level containlerLiquid aim SwitchesLiquid train Sensors Level SensorsLevel commands piddle Quality testing instrumentsLevel GuagesPh simplenessllers Introduction to water system Level Controller In most houses,water is first stored in an resistance tank (UGT) and from there it is pumped up to the overhead tank (OHT) located on the roof. People generally switch on the pump when their lights-out go change and switch off the pump when the overhead tank starts overflowing. This results in the unnecessary wastage and sometimes non-availability of water in the case of emergency. The simple circ uit presented here makes this system automatic, i.e. it switches on the pump when the water level in the overhead tank goes low and switches it off as soon as the water level reaches a pre-determined level. It also prevents dry run of the pump in case the level in the underground tank goes below the suction level. In the figure, the common probes connecting the underground tank and the overhead tank to +9V generate are marked C. The new(prenominal) probe in underground tank, which is slightly above the dry run level, is marked S. The low-level and racy-level probes in the overhead tank are marked L and H, respectively. When there is enough water in the underground tank, probes C and S are connected through water. As a result, transistor T1 gets foregoing biased and starts conducting.This, in turn, switches transistor T2 on. Initially, when the overhead tank is empty, transistors T3 and T5 are in cut-off state and hence pnp transistors T4 and T6 get forward biased via resistors R5 and R6, respectively. As all serial publication-connected transistors T2, T4, and T6 are forward biased, they conduct to energise relay RL1 (which is also connected in series with transistors T2, T4, and T6). Thus the supply to the pump motor gets completed via the lower set of relay contacts (assuming that switch S2 is on) and the pump starts filling the overhead tank. at a time the relay has energised, transistor T6 is bypassed via the upper set of contacts of the relay. As soon as the water level touches probe L in the overhead tank, transistor T5 gets forward biased and starts conducting. This, in turn, reverse biases transistor T6, which then cuts off. But since transistor T6 is bypassed through the relay contacts, the pump continues to run. The level of water continues to rise. When the water level touches probe H, transistor T3 gets forward biased and starts conducting. This causes reverse biasing of transistor T4 and it gets cut off. As a result, the relay de-energises a nd the pump stops. Transistors T4 and T6 will be move on again only when the water level drops below the position of L probe. Presets VR1, VR2, and VR3 are to be adjusted in such a way that transistors T1, T3, and T5 are turned on when the water level touches probe pairs C-S, C-H, and C-L, respectively. Resistor R4 ensures that transistor T2 is off in the absence of any base voltage. Similarly, resistors R5 and R6 ensure that transistors T4 and T6 are on in the absence of any base voltage. Switches S1 and S2 can be used to switch on and switch off, respectively, the pump manually.You can make and install probes on your own as per the requirement and facilities available. However, we are describing here how the probes were made for this prototype. The author used a piece of non-metallic conduit pipe (generally used for domestic wiring) slightly longer than the deepness of the overhead tank. The common telegram C goes up to the end of the pipe through the conduit. The wire for prob es L and H goes along with the conduit from the outside and enters the conduit through cardinal small holes bored into it as shown in Fig. 2.Care has to be taken to ensure that probes H and L do not touch wire C directly. insulation of wires is to be removed from the flushs shown. The same arrangement can be followed for the underground tank also. To avoid any false triggering due to interference, a shielded wire may be used.The Water Level Controller System is an electronic Equipment which when electrically connected to the starter of any given Pump-set motor will control the operation of the pumpset depending upon the water level in the Source and Destination Storage Tanks.Advanced Automatic WATER LEVEL CONTROLLER unit Manufactured by M.V.Instruments is a Microprocessor based Electronic Device. This system when electrically connected to an Pumpset starter, performs the following functions automaticallySwitches ON the Pump set when Water level drops below pre-set level (i.e. T2 level) in Overhead Tank.Switches collide with the Pump set when Water level in Overhead Tank becomes full (i.e. T1 level).Switches OFF the Pump set when Water level is low in Sump/Well/Borewell (i.e. S2 level).Switches ON the Pump set when there is sufficient water in the Sump/ Well / Borewell (i.e. S1 level).Switches OFF the Pump set when there is a Dry run (i.e. when Water is not being pumped into Overhead Tank due to any reason). small-scale Voltage and High Voltage Protection for the Pump set is incorporated.The system has Surge Voltage/Current Protection for the Pump set.All these functions are automatically performed. Manual interference is absolutely not required.Manual operation is also possible if and when required by operating the switch in Manual Position.nonsuch Water Filters use a unique 5-Stage filtration system that combines the cleaning capabilities of Activated Carbon with the new technology of KDF-55The first stage consists of a micro beatnik caliper distort loc ked into place, preventing water from forming paths or channels along the sides of the unit. Once the first micron filter has removed any large particles, the water goes through a series of chambers FIVE STAGES IN ALL.The media filtration process begins with KDF-55, which uses an electrochemical process to reduce Chlorine and improve taste and odor.Water passes through progressively finer micron filters as it travels through the unit, to assure removal of particles and to separate the media so that they operate at maximum effectiveness.The final chamber contains the senior high schoolest quality Granular Activated Carbon. Water tastes best when aerated with carbon, so this final stage assures that you water is as refreshing as it is clear.Principle The Autonics Water Level Modulating controlsystem is a single element Electro-pneumaticcontrol with a pneumatic Positioner and PID/ befuddledsystem.
