Flow Meters: Essential Guide for Industrial Applications
As critical components in process automation, flow meters rank among the top three measured parameters. This guide explains core concepts for various industries.
1. Core Flow Concepts
Volumetric Flow
Measures fluid volume passing through pipes:
Formula: Q = F × v Where F = cross-sectional area, v = velocity
Common Units: m³/h, L/h
Mass Flow
Measures actual mass regardless of conditions:
Key Advantage: Unaffected by temperature/pressure changes
Common Units: kg/h, t/h
Total Flow Calculation
Volume: Gtotal = Q × t
Mass: Gtotal = Qm × t
！Always verify measurement units to prevent errors.
2. Key Measurement Objectives
Process Control
- Real-time system monitoring
- Equipment speed regulation
- Safety assurance
Economic Accounting
- Resource tracking
- Cost management
- Leak detection
3. Flow Meter Types
