Abstract
- Flowmeter adapters include thread types (internal/external), pipe insertion, and weld connections, each suited for specific methods.
- Choose the correct adapter based on precise pipe outer diameter measurements, considering material differences like stainless steel versus plastic.
- During installation, avoid over-tightening to prevent leaks or damage to the flowmeter.
1. Flowmeter Connections Types
Flow meter connections are categorized into two main types: threaded and insertion. Special attention is needed when connecting different materials to avoid debris that could lead to blockages.
