Essentials™ Crude Oil Sampler

WELKER > Crude Oil Sampling > Crude Oil Composite Samplers > Essentials™ Crude Oil Sampler

Economical Crude Oil Sampler

Sampling low volumes of low-pressure, low-viscosity crude oil? Welker has a low-cost, low-maintenance solution. The Essentials™ Crude Oil sampler is a probe-mounted volume regulator with a 3-way solenoid for remote operation. Avoid the inaccuracies and potential hazards of manual tank gauging by including the Essentials™ on your Lease Automatic Custody Transfer (LACT) Unit for truck and rail car loading or unloading.

Complies WithAPI Chapter 8.2, ASTM D4177, ISO 3171

More Bang For Your Buck

Practical Value

For low frequency sampling of low-density stabilized light crude oils, you don’t need a sampler that breaks the bank. The Essentials™ is the no-frills sampler you need. Install it directly to your low-pressure line and connect the 3-way solenoid to your Programmable Logic Controller (PLC) or other control device to pace the sampler for proportional to flow or timed sampling. Collect composite samples in an atmospheric container, such as a Welker SCC or Welker TCC.

Outer Limits

External Sample Volume Adjustment

With an externally adjustable sample volume, the Essentials™ can be easily set from 2–5 cc or from 2–10 cc to suit your sampling requirements. When the solenoid is energized, line pressure fills the Welker Volume Regulator with the desired volume of sample. Trapped under pressure, the sample volume is injected into the connected atmospheric container when the solenoid is de-energized.

Without Interruption

Easy Maintenance

There’s no need to depressurize your pipeline and remove the Essentials™ Crude Oil Sampler for standard maintenance. Closing the valve on the probe isolates the solenoid and Welker Volume Regulator from process pressure, enabling you to safely remove them.
