A "Fixed Resistor" Flow Limiting Orifice Flowmeter On The Pipeline
An orifice plate flowmeter is a simple throttling device that limits, stabilizes or distributes flow by creating a fixed pressure drop.
Main advantages:
- Extremely simple structure and low cost.
- No moving parts, high reliability and maintenance-free.
- Clear and effective functions: very reliable in limiting flow and stabilizing pressure.
- Adaptable to harsh working conditions: suitable for high temperature, high pressure and corrosive media through the selection of appropriate materials and multi-stage design.
Typical application scenarios:
- Safety protection: Recirculation lines for pumps, anti-surge bypasses for compressors, to limit minimum flow.
- Pressure distribution: Before manifold or parallel equipment to ensure balanced pressure in each branch.
- Pressure reduction and buffering: Installed before high-pressure control valves to reduce pressure before the valve and extend valve life.
- Sampling system: Provide stable small flow samples for online analyzers.
- Relief device: As a small safety relief valve or auxiliary relief for flare systems.
- Test bench: Provide a fixed flow resistance in fluid test systems.
The flow-limiting orifice plate is a "functional" throttling element rather than an "instrumental" measuring element.
