Operation Description of the Two Reed Switches System
The diagram illustrates a system with two reed switches. These switches are activated (“ON”) or deactivated (“OFF”) by a magnet attached to the pointer or gear of a register. The magnet operates each switch individually, ensuring that they are never both “ON” at the same time, except in the case of an external magnetic interference.
When the pointer or gear completes one full rotation, the two reed switches activate and deactivate in a specific sequence, generating a single signal output. This mechanism prevents signal loss or overcounting that might occur due to switch movement or pipe vibration. By ensuring a reliable and consistent signal output, this system enhances the overall reliability of the register.
Warranty
All meters will be guaranteed against defects in workmanship and material for a period of 1 year from the date of delivery. Defective meters or parts discovered within this period shall be replaced without charge upon return to the Bridgetech Innovations.
