Smart Utility Meters Use Reed Sensors To Measure Water Flow, Gas and Electricity
Most households and businesses have meters reading and recording the volume of water used, the volume of gas used and/or the amount of electricity being used. Most of these meter use reed sensors to count and measure the usage for each household. This is done in a power efficient and tamper proof way using reed sensors.
Full application writeup: Water, Gas and Electricity Meters use Reed Sensors
- Magnet and reed sensor are isolated and have no physical contact by typically having the magnet mounted to a mini paddle wheel, and the reed sensor is mounted strategically such that the magnetic field of the permanent magnet will be sensed with each rotation of the paddle wheel.
- The reed switch used in the reed sensor is hermetically sealed and is therefore not sensitive to wet, watery environment
- The permanent magnet is not affected by its environment
- Tens of millions of reliable operations
- Surface mounting and through hole mounting
- Contacts dynamically tested
