Swagelok E-69 area flow meter product leaflet with specifications, installation guidance and optional accessories.
The Swagelok E‑69 area flow meter series (G‑Series glass tube and M‑Series metal tube) provides highly accurate flow measurement for gases and liquids. The leaflet describes the construction, material options, and performance ranges for each model (E‑69 to E‑78), including optional limit switches and electronic displays.
Installation must be vertical for most models (MH model may be mounted horizontally). The document also covers factory calibration procedures, cleaning, custom calibration options, and ordering codes for configuring specific model options. This manual is written in Japanese.
| Air flow range (standard) | 0.5 – 5.0 std L h |
|---|---|
| Water flow range (standard) | 0.25 – 2.5 L h |
| Maximum allowable error formula | E = (0.75 M + 0.25 F) × A × 100 |
The meter must be installed vertically; only the MH model may be installed horizontally.
Use the formula E = (0.75 M + 0.25 F) × A × 100, where M is the measured flow, F is the full‑scale flow, and A is the accuracy class.
