Most water meters are equipped to provide pulse output. That means they have a magnet on either a visible dial, or an internal part of the mechanical drive train. A reed switch, positioned in such a manner that the passing magnet will pull it closed, allows the switch to create a "dry contact closure" pulse. It's just like turning a light switch on and off. Depending on where this magnet is located (what dial it is on) the pulses represent different volumes of water.

Pulse output is used to allow the water meter to communicate with external electronic equipment.
- Simple Pulse Counter (many to choose from in the "Add Accessories" section)
- A transciever that communicates with a gateway for a wireless submetering system
If this is an option for the meter that you are specifying, then the meter already has the magnet in it.
By selecting anything other than "None", you are simply buying a wire with the reed switch on it.
The switch will come preinstalled on the meter.
