Understand and calculate delays in Swagelok analysis instrument systems to ensure accurate results.
This guide explains the causes of delay in analysis instrument systems and how to calculate and optimize them. Delays occur from sampling points to analyzers and are cumulative. The document covers delays in piping, sampling points, field stations, and probes, with formulas and examples for liquids and gases. It also discusses how to reduce delays using pressure regulators, quick loops, and optimized probe placement.
The guide includes practical examples for calculating delay times in different scenarios, such as liquid and gas flow through pipes and probes, and how to adjust for pressure differences. It also addresses flow switching components and how to minimize delay using integrated flow loops and proper valve selection. This manual is written in Chinese.
| Delay Calculation Formula for Liquids | Delay = Pipe Length / (Flow Rate / Unit Length Volume) |
|---|---|
| Delay Calculation Formula for Gases | Delay = Pipe Length / [(Flow Rate / Unit Length Volume) × (Pressure Ratio)] |
| Probe Volume Impact | Delay increases with probe volume |
Use the formula: Delay = Pipe Length / (Flow Rate / Unit Length Volume).
Use the formula: Delay = Pipe Length / [(Flow Rate / Unit Length Volume) × (Pressure Ratio)].
Install a pressure regulator near the sampling point to reduce pressure and increase flow speed.
