Water Flow Alarm Circuit
A water flow detector commonly produced by system sensor is an electro mechanical device designed to send an alarm to a fire alarm panel and or fire department when a continuous flow of water occurs through the fire sprinkler system s piping from an activated sprinkler head or leak in the system.
Water flow alarm circuit. Whenever tank gets filled we get alerts on particular levels. When the building sprinkler system activates the waterflow switch has three main functions. What happens is the flow switch short circuits the buzzer and light emitting diode led when there is flow the 100ω resistor limiting the current to a safe 0 12a the flow switch can switch 1 0a. Here is a simple water overflow alarm circuit to prevent overflow of water from overhead tanks.
With both alarm and chime modes use the sk630 to add security or convenience. As water will be full contact to the wire then buzzer will start giving sound. Here we have created 4 levels low medium high and full we can create alarms for more levels. Both ic1 and ic2 are wired in astable multivibrator mode.
It detects water flowing in the sprinkler system and causes the fire alarm system to sound the evacuation. In alarm mode the sensor will trigger a loud 105db 30 second alarm. A waterflow switch is the interface between the building s fire suppression system and the building s fire alarm system. The circuit can be implemented to fit other applications as well that require liquid level measurement.
Nowadays all the householders owners are storing the water in overhead tanks by using the pumps. Get notified of visitors intruders or passers by with the sk630 pressure mat alarm. The sensor is triggered when stepped on activating a pleasant chime or loud alarm. This type we can make over flow water alarm circuit.
When flow stops and the flow switch opens the buzzer and led will operate at about 9v. This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank. And we can do silent of buzzer by opening the battery.
