What you may be referring to, since the question was posted in electrical engineering section, is in reference to the electrical switches and devices installed on sprinkler systems. The systems have water flow devices, low air switches, valve tamper devices and the like. each device is designed to monitor changes in state in the system. (sprinkler waterflow, low air pressure in a system, an improperly open or closed valve, to name a few.) these devices are designed to send an electrical current or signal of high or low voltage to a device(bell or siren) or to an alarm or control panel. The terminals on these devices are similar. They have a "common" terminal. Next, they have an "normally open" terminal; which means the circuit is open normally, but closes during a change in state. The circuit is supervised with a end of line resistor in the circuit, hence an "open loop"

What is open loop and close loop system?
Q: What is the difference between 'Open Loop' and 'Closed Loop'? A: When the engine is first started, and rpm is above 400 rpm, the system goes into 'Open Loop' operation. In 'Open Loop', the ECM will ignore the signal from the Oxygen (O2) sensor and calculate the air/fuel ratio based on inputs from the coolant and MAF sensors, but mostly from a pre-programmed table in the memcal. The system will stay in 'Open Loop' until the following conditions are met: 1. The O2 sensor has varying voltage output, showing that it is hot enough to operate properly. (This depends on temperature) 2. The coolant sensor is above a specified temperature about 40oC/104oF. 3. A specific amount of time has elapsed after starting the engine. The specific values for the above conditions vary with different engines and are stored in the mem-cal. When these conditions are met, the system goes into 'Closed Loop' operation. In 'Closed Loop', the ECM will calculate the air/fuel ratio (injector on-time) based on the various sensors but mainly the O2 sensor. This allows the air/fuel ratio to stay very close to 14.7:1.

Why kirchhoff's voltage law is applicable for open circuit?
Kirchoff's Voltage Law does not work, per se, for open circuits. You need a closed circuit for it to make any kind of sense.The signed sum of the voltage drops going around a series circuit is equal to zero.That means you have a closed circuit.However, it can be argued, correctly, that an open circuit is simply one that has two nodes with infinite resistance between them. Assuming that all of the other nodes have something less than infinite resistance between them, then Kirchoff's law does work, of sorts, in that the voltage drop across all nodes that are not voltage sources will be zero, because there is no current, and the voltage drop across the two nodes with infinite resistance will be equal to the sum of the voltage rises across the voltage sources. Current sources in such a circuit will not work, because, with zero current, they would attempt to generate infinite voltage.AnswerKirchhoff's Voltage Law does indeed apply to an open circuit, because the voltage drop across the open part of the circuit is numerically equal to the supply voltage and, hence, the algebraic sum of the voltage drops around that particular loop is zero.Kirchoff's Voltage Law does not work, per se, for open circuits.

What is system earthing and equipment earthing?
System Earthing is the earthing associated with current carrying conductor & is essential for the security of the system. Equipment Earthing is the earthing associated with non-current carrying metal work & is essential for the security of human life and property.
Why do electric circuits have to be complete?
if they're not then the circuit will not work and it won't be able to power wat u want it to power for example a lightbulb.it will be an open circuit
How does a sprinkler valve work to control the flow of water in a sprinkler system?
A sprinkler valve works by opening and closing to control the flow of water in a sprinkler system. When the valve is open, water is allowed to flow through the system and reach the sprinkler heads, which then spray water onto the desired area. When the valve is closed, water flow is stopped, preventing water from reaching the sprinkler heads. This allows for precise control over when and where water is distributed in the sprinkler system.
How do sprinkler valves work to control the flow of water in a sprinkler system?
Sprinkler valves work by opening and closing to regulate the flow of water in a sprinkler system. When the valve is open, water is allowed to flow through the pipes and out of the sprinkler heads, watering the designated area. When the valve is closed, water flow is stopped, preventing water from reaching the sprinkler heads. This control is typically achieved through the use of a solenoid that is activated by an electric signal, allowing for precise control over when and how much water is distributed.
How can I effectively blow out my sprinkler system using an air compressor?
To effectively blow out your sprinkler system using an air compressor, follow these steps: Shut off the water supply to the sprinkler system. Connect the air compressor to the sprinkler system's main line using an air hose. Set the air compressor to a low pressure setting (around 50-80 psi). Open the manual drain valves on the sprinkler system to allow water to drain out. Turn on the air compressor and slowly increase the pressure to blow out any remaining water in the system. Work your way through each zone of the sprinkler system, ensuring all water is expelled. Once all zones are clear, turn off the air compressor and disconnect it from the system. Open the main valve to allow any remaining water to drain out. By following these steps, you can effectively blow out your sprinkler system using an air compressor.
How does a sprinkler system work?
A sprinkler system works by pushing water through a hose or underground water pipes and releasing the water through a sprinkler nozzle. These can be used manually or automatically through electronic systems.
If you did not use your sprinkler system do you need to Winterize it?
winterize it only if you want it to work in the future

How to properly blow out your sprinkler system for winterization?
To properly blow out your sprinkler system for winterization, you will need an air compressor with a cubic feet per minute (CFM) rating of at least 80-100. Start by shutting off the water supply to the sprinkler system and opening the drain valves. Connect the air compressor to the sprinkler system using a quick-connect fitting. Gradually increase the air pressure to blow out the water from the pipes and sprinkler heads. Work zone by zone, ensuring all water is expelled. Once completed, disconnect the air compressor and close all drain valves. This will help prevent freezing and damage to your sprinkler system during the winter months.

What are the best and where do I find more info on a sprinkler system?
The best place to find more information on sprinkler systems is to contact a local professional. You can find helpful contractors who will work with you on what you envision for your yard, or you can also check out a home improvement store.
In my Sims kingdom Wii how do you make the sprinkler?
You do not need the sprinkler use the t pipe to drop water on the plant and using that is easier than the sprinkler since it does not work Your welcome
