# Industrial Specification: Flow Meter Sensor

## 1. Technical Definition
A sensing device that measures the flow rate of liquids or gases within a flow control system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 m/s flow velocity, -40°C to 150°C temperature, 0-100 bar pressure**. Failure boundary: **Flow velocity exceeding 120 m/s causes impeller deformation, temperature beyond 180°C degrades piezoelectric crystal response, pressure above 120 bar ruptures diaphragm seals**, Mechanism: **Cavitation at vapor pressure below 0.023 bar causes impeller erosion, thermal expansion mismatch between stainless steel housing (17.3 μm/m·K) and ceramic sensor (5.5 μm/m·K) creates microcracks, electromagnetic interference above 100 V/m disrupts Hall effect sensor signals**.

### 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.
