Notes When handling the glass taper tube flowmeter, please consider the following points:
1. Choose an installation location with minimal vibration.
2. Be aware that impact pressure can damage the glass.
3. Rapid float rise during ON/OFF operations might also damage the glass.
4. Avoid thermal shock from rapid cooling or heating to prevent glass damage.
5. If measuring liquids with a freezing risk, ensure to drain them to protect the glass.
