# Industrial Specification: Precision Flow Controller

## 1. Technical Definition
A device that precisely regulates the flow rate of fluids (liquids or gases) within an industrial system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 bar differential pressure, 0.01-100 L/min liquid flow, 0.1-1000 SLPM gas flow**. Failure boundary: **150 bar differential pressure (diaphragm rupture), 120°C fluid temperature (seal degradation), 0.5 μm particle size (orifice clogging)**, Mechanism: **Cavitation at vapor pressure &lt;0.1 bar absolute, thermal expansion mismatch at ΔT&gt;50°C, abrasive wear at particle velocity &gt;2 m/s**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
