Selection guide
- DK46 vs 47 vs 48 vs 800
- Float / scale fluid
- Needle valve / fittings
- Pressure limit of glass
Common mistakes
- Exceeding ~10 barg on glass tubes.
- Using glass VA on opaque/dirty media that hide the float.
- Ordering DK46 when DK48 accuracy is required.
When to RFQ / what to tell us
- DK model, fluid, flow.
- Connections, quantity, ship-to.
