1.2 Product Description
The Welker inFlow™ ACE Crude OilSampler is a direct-mount isokinetic probe sampler designed to extract a representative
sample of liquid product from the flowing stream. Once all desired samples have been collected, the inFlow™ ACE can be fully
evacuated of internal sample volume using the purge tube, thus preparing the sampler for the next sample batch.
Sampling may be hydraulically or pneumatically operated but is electronically controlled from a Programmable Logic Controller
(PLC) or other signal control system. Sampling may be timed or proportional to flow.
With protection from an external sand relief and check and relief valves designed for sandy oils, this sampler is capable of
sampling product containing sand or debris. For added safety, the inFlow™ ACE is equipped with a dustcover, shaft wipers to
protect seals, and an adjustable V-ring packing for emergency shutdown leak protection.
Designed with ease of use in mind, the external sample volume adjustment simplifies operation of the inFlow™ ACE even further.
The external adjustment allows the operator to adjust the sample volume without having to remove the inFlow™ ACE from the
pipeline.
For this manual, the term "PLC," or Programmable Logic Controller, will be used to refer to the PLC, DCS, or other signal control
system used by the customer to activate and operate the solenoid.
Welker may custom design the inFlow™ ACE to suit the particular application and specifications of each customer.
1.3 Important Information
1. The lubrication port should remained plugged at all times except when performing maintenance on a sampler that has
been isolated from pipeline pressure and/or removed from the pipeline.
2. Prior to injecting Welker Great Barrier Sealant™ into the lubrication port, the plug must be removed and an
appropriately sized grease fitting installed.
3. After Welker Great Barrier Sealant™ has been injected into the lubrication port, the grease fitting must be removed and
the plug reinstalled before the sampler can be exposed to pipeline pressure and returned to operation.
Failure to remove the grease fitting and return the plug to the lubrication port prior to exposing the sampler to pipeline
pressure could result in a product leak and/or injury to the operator.
