Level Indicator/Working and its uses

By Prathima
Level indicators   Level indicator is used to detect liquid levels. This is mainly used in water treatment plants, Sewage treatment facilities, buildings , housing complexes and so many other appliances. It will sense lower to higher level of water which is connected to control panel to give the information about the level of liquids. Water level indicator is a combination of probe  sensor or float switches. Working of level indicator   The mechanism of level indicator is quite simple. It will sense the level of liquid in storage tank by using sensor probes. When water reaches a certain level it will give signal to your connected device(Probes send information back to the control panel to trigger an alarm or any indicator. When we are using any type of sensor our motor is to control all the equipment automatically, here  also same, when you connecting the level indicator in storage tank, the control panel can be programmed to automatically turn on or off ...

Counter and its Function/Automation/Industrial Automation/PLC counter

By Prathima
What is counter A counter may be a digital circuit or device that counts the amount of products and returns predefined values supported clock pulse applications. The output of the counter are often wont to count the amount of pulses. The counter circuit is typically composed of several flip-flops connected within the cascade method. Counter automation and digitally based components are very widely used components.      Micro controller applications require external events or precise internal time delay generation and calculation of pulse frequency as required . These phenomena are often utilized in digital systems and automation. Both of those events are often performed by software techniques, but software loops for counting won't give accurate results, as little more important work isn't done. These problems are often corrected by timers and counters in micro controllers that are used as interrupts. Classification of counters In digital circuits, counters ...

What Is SCADA System

By Prathima
SCADA                 Supervisory Control and Data Acquisition or SCADA is an automation control system used in industries such as energy, oil and gas, water power and many more.         The system has a centralized system that monitors and controls the entire country from industrial plants to plant premises.             The SCADA system works by working with signals that communicate through channels to provide the user with remote control of any device in a system.        There are some essential parts composed of highly controllers and monitoring Systems. 1. SCADA system human machine interface or HMI supervisory system remote terminal units 2. RTu  use programmable logic controllers or PLC and communication infrastructure. HMI processes the data and sends it to the human operator. Where they can monitor or control the system.          The supervi...
