Dwyer 4000 Series Capsuhelic® differential pressure gauge
Capsule-type differential pressure gauge, system pressure up to 500 psig, suitable for liquids, filter pressure drop and tank level measurement.
- Original Factory Genuine, Tenfold Compensation for Counterfeits
- Full Machine Warranty, Lifetime Maintenance
- In Stock, Shipped on the Same Day
The 4000 Series Capsuhelic uses a capsule-type measuring structure and can withstand system pressures up to 500 psig, while still resolving minute differential pressures of 0.1″ w.c. in high-pressure lines. Suitable for liquid filter pressure drop, tank level conversion and gas differential pressure measurement; the aluminium case is for gases, the brass case for water and water-based liquids.

| Model selection | |
| Selection table | Published on the official website as a screenshot of the selection table; for complete model numbers and ranges, see the official manual "4000 .pdf" in the documentation package. |
- Capsule (Capsuhelic) structure, can withstand 500 psig system pressure
- Still resolves minute differential pressures of 0.1" w.c. at high pressures
- Aluminium case for gases, brass case for water and water-based liquids
- Suitable for local reading of liquid filter pressure drop and tank level
Liquid filter pressure drop monitoring
Pressure is tapped at the filter inlet and outlet; the differential pressure gauge directly indicates the degree of element clogging.
Converted tank level reading
The liquid level height is converted on the dial using the hydrostatic level differential pressure, for local indication on atmospheric tanks.
