It helps in faster way of communication and it helsaving the water form wastage.

This would bring the transparency in public distribsystem as there will be a direct communication betwpeople and Government through this system.

Using such a system, Government would have all

These units are ideal for use in water conservationstorage tanks, water recycling home applications,systems and much more. The sensors are solidly const

provide a digital pulse each time an amount of wathrough the pipe. The output can easily be connemicrocontroller for monitoring water usage and calcuamount of water remaining in a tank etc.

This flow sensor is suitable for a standard pipe. A w

voltage can be connected to the unit. The unit is conlong-life polymer and is suitable for outdoor mounting. Tto connect units are ideal for use in environmentahousehold water management systems.

How does it works ????

It an accurate and reliable flow meter for liquids

gases. It consists of a slightly magnetic multi blaspinning rotor (impeller) mounted inside at rightto the flow.

The rotor is suspended in the flow by 2 end suppwhich act to straighten the flow prior to reachingblades.

As the flow reaches the turbine, the turbine begispin due to the applied force by the flow. As suchrotation of the rotor is proportional to the rate of

Due to the action of rotation

Due to the rotation of the blades we use the mec

energy of the fluid to rotate a pinwheel (rotor) flow stream. Blades on the rotor are angled to trenergy from the flow stream into rotational enerrotor shaft spins on bearings. When the fluid mofaster, the rotor spins proportionally faster.

Shaft rotation can be sensed mechanically or by the movement of the blades.Blade movement is detected magnetically, with each blade or embedpiece of metal generating a pulse.

Action of sensor

Inductance type sensor generates a voltage puls

time a rotor blade passes by. Depending on the tof signal receiving instrument a pre-amplifier mneeded. The Hall-effect sensor provides a squareoutput each time a blade passes by and has a bupre-amplifier. The Hall-effect sensor also produce

magnetic drag on the rotor and is more suitable flow rates.
