# Industrial Specification: Float Assembly

## 1. Technical Definition
A mechanical assembly containing a buoyant float that moves with liquid level changes in a tank or vessel.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-2.5 bar differential pressure, -20°C to 120°C temperature, 0-100% liquid level**. Failure boundary: **3.0 bar differential pressure causing float deformation, 150°C temperature causing seal degradation, 0.5 mm float-to-guide clearance loss**, Mechanism: **Plastic deformation of float material (typically polypropylene) exceeding yield strength at 3.0 bar, thermal degradation of elastomeric seals above 150°C, mechanical wear exceeding 0.5 mm clearance causing binding**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Corrosive fluid exposure exceeding pH 2.0 or pH 12.0 | 8 | Float material degradation and buoyancy loss | Material substitution to PTFE-coated stainless steel with 0.1 mm coating thickness |
| Mechanical vibration exceeding 5.0 g RMS at 10-1000 Hz | 8 | Guide rod wear exceeding 0.5 mm clearance causing binding | Installation of vibration isolators with 85% damping efficiency and hardened steel guides with 60 HRC hardness |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

### Industrial DNA Context (De-duplicated)
**Complementary Dependencies**: **Liquid Level Transmitter**, **Control Valve Assembly**, **Process Tank or Vessel**  
**Downstream Applications**: Liquid Level Indicators, Automated Tank Monitoring Systems, Process Control Equipment  

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

### Q: What materials are available for float assemblies in corrosive applications?
**A**: Float assemblies are available in corrosion-resistant materials including stainless steel (general use), polypropylene (chemical resistance), PTFE/Teflon (high chemical inertness), and Hastelloy (extreme corrosion environments).

### Q: How does a float assembly work in liquid level monitoring?
**A**: A buoyant float moves vertically with liquid level changes in a tank. This mechanical movement can actuate switches, magnets, or indicators through the stem/rod assembly to provide level measurement or control signals.

### Q: What components make up a standard float assembly BOM?
**A**: Standard bill of materials includes: float body (buoyant element), stem/rod (connection component), magnet assembly (for magnetic switches), guide/stabilizer (for vertical alignment), and seals/gaskets (for leak prevention).

## 6. Manufacturing Compliance
- ISO 9001:2015 - QUALITY MANAGEMENT SYSTEMS
