# Industrial Specification: Water Level Indicator

## 1. Technical Definition
A device that visually or electronically displays the current water level within a tank.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-100% full scale with ±1% accuracy at 20°C ambient temperature**. Failure boundary: **Exceeds 125°C operating temperature or experiences &gt;50g shock acceleration**, Mechanism: **Thermal expansion mismatch between float magnet assembly and guide tube causing binding, or Hall effect sensor saturation beyond 100mT magnetic flux density**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electrolytic corrosion in float chamber due to pH&lt;6.5 water chemistry | 8 | Float buoyancy loss causing 0% reading regardless of actual level | 316L stainless steel float with epoxy coating and cathodic protection at -0.85V vs Ag/AgCl reference |
| EMI induction from adjacent VFD cables exceeding 100V/m field strength | 8 | ADC sampling errors producing ±15% reading oscillations | Shielded twisted pair wiring with ferrite chokes and 4-20mA current loop isolation |
