Abstract:
A pulse encoder for a sensor interface module, said pulse encoder for use with an existing meter having a meter dial, said encoder comprising:an encoder shaft having a first end with a top and bottom, and a second end having an attachment clip, wherein said bottom is slotted to fit over a meter dial and said top has a shoulder; a surrounding spring mounted around said encoder shaft and biased against said shoulder; an encoding magnetic field generator having a central opening therethrough, wherein said generator is mounted over said encoder shaft in order to rotate with said encoder shaft and biased against said surrounding spring; and a magnetically actuated reed switch positioned adjacent to said shaft having two flexible reeds, wherein each reed has a contact point for connecting and deconnecting with the contact point of the other reed whereby the rotation of a magnetic field by the magnetic field generator causes the connecting and deconnecting of said contacts.
