Component Specifications

Definition
The flow body and metering section is a critical component of reference flow sensors, designed to create a stable, predictable flow profile for precise measurement. It consists of a precisely machined housing that directs fluid through a calibrated metering section where flow parameters are measured using integrated sensing elements. This component ensures minimal turbulence, pressure drop, and measurement uncertainty while maintaining compatibility with various process fluids and operating conditions.
Working Principle
The flow body creates a controlled flow path that stabilizes fluid movement, while the metering section provides a consistent cross-sectional area where flow velocity or volumetric rate can be accurately measured using differential pressure, thermal, or ultrasonic sensing methods. The design follows fluid dynamics principles to minimize flow disturbances and ensure measurement repeatability.
Materials
Stainless steel (316L, 304), Hastelloy C-276, Titanium Grade 2, PEEK, PTFE, depending on chemical compatibility requirements. Surface finish: Ra ≤ 0.8 μm for wetted surfaces.

Frequently Asked Questions

What is the difference between flow body and metering section?

The flow body is the main housing that directs fluid flow, while the metering section is the specific area within the body where flow parameters are measured with precision instruments.

How often should flow body components be calibrated?

Calibration intervals depend on usage and process conditions, typically every 6-12 months for critical applications, or as recommended by manufacturer and quality standards.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
