# Industrial Specification: Flow Meter

## 1. Technical Definition
A device that measures the volumetric or mass flow rate of a fluid within a spray system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-100 L/min at 1-60 bar, fluid temperature -20°C to 120°C**. Failure boundary: **Pressure exceeding 80 bar causes permanent deformation of turbine blades or ultrasonic transducer damage; flow rates below 0.2 L/min cause measurement inaccuracy exceeding ±5% FS**, Mechanism: **Cavitation at vapor pressure below 0.5 bar absolute causes bubble implosion damaging turbine blades; piezoelectric crystal fatigue at temperatures above 120°C degrades ultrasonic signal accuracy**.

### 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.

| Symbol | Variable Definition | Localized Reference |

| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding 50 μm diameter in fluid stream | 8 | Turbine bearing seizure or ultrasonic transducer surface abrasion | Install 40 μm absolute filtration upstream with differential pressure monitoring |
| Water hammer pressure surge exceeding 1.5× rated pressure for &gt;100 ms | 8 | Diaphragm rupture in differential pressure sensors or piezoelectric crystal fracture | Install surge suppressor with 10 ms response time and pressure relief valve set at 1.2× operating pressure |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are available for the flow meter housing in spray systems?
**A**: Our flow meters are available in stainless steel for durability, brass for cost-effective applications, and plastic materials like PVC or PTFE for corrosion resistance in chemical spray systems.

### Q: How does the flow meter measure fluid flow rates in industrial spray equipment?
**A**: The flow meter uses a sensor/transducer to detect fluid movement, with electronics/transmitter converting this data into volumetric or mass flow rate measurements displayed on the indicator for precise spray system monitoring.

### Q: What maintenance is required for flow meters in machinery manufacturing applications?
**A**: Minimal maintenance is needed with proper installation. Regular calibration checks, cleaning of sensor components, and inspection of housing seals ensure accurate, long-term performance in industrial spray environments.
