Different water meter brand?

Our sensor detects the metal rotating disc in analog water meters. This small metal disc (often silver-colored) rotates when water flows through. The sensor registers each rotation via magnetic detection = 1 liter of water. ⚠️ No rotating metal part? Then our sensor won't work.
