Description
Honeywell’s HERMetic Samplers A-2 and A-4 are dedicated to applications where restricted sampling is authorized.
A restricted system exists when a marine tank vessel allows some vapors from its cargo tanks into the atmosphere under normal operating conditions. The samplers are used for crude oil sampling on tankers and very large crude carriers (VLCCs).
What Is It?
HERMetic Sampler A-2: Its key features include:
- Used for connection on 2-inch HERMetic compact valves
- For applications involving liquids with low or high viscosity
- Ideal for use under open operations
- Easy installation on 2-inch vapor control valves with quick connect coupling
- Sampling height can be measured on the graduated tape
- Sampling bottle can be easily removed and exchanged
- Delivered with a zone sampling bottle - spot, running and bottom sampling bottles are also available on request.
HERMetic Sampler A-4: Key features include:
- Used for large volume sampling of up to 1.8 liters under open operations
- Easy installation on a 4-inch deck valve
- Sampling height can be read on the graduated tape
- Sampling bottle can be easily removed and exchanged
- Delivered with a zone sampling bottle; spot, running and bottom sampling bottles also available.
How Does It Work?
The sampler housing is mounted on top of the HERMetic 2” ball valve or a 4” deck valve, depending on the type of sampler model. The sample is taken through the vertical movement of the sampling bottle inside the liquid. The bottle is linked to a graduated tape. A reading window allows users to monitor the bottle location.
What Problems Does It Solve?
Honeywell’s samplers for restricted operation offer easy installation, low costs and clean operation during sampling. It permits taking a representative sample of the content inside the tank for further analysis in a laboratory.
