Verify sample bite size and monitor sampler performance from one convenient panel.
The Welker Checkpoint™ Sample Bite Verification Panel is designed for automatic liquid sampling systems that require convenient sample grab size confirmation, sampler performance monitoring, and overpressure protection. By allowing operators to verify actual sample volume settings and check repeatability for adjustable or non-adjustable samplers, Checkpoint™ helps improve batch sampling frequency, reduce sample bias, and validate crude oil or liquid hydrocarbon sampling system performance. With a quick-connect outlet and tubing, outlet check valve, pressure switch with externally adjustable relief valve, and modular panel configurations, Checkpoint™ provides a simple upgrade for new or existing automatic sampling systems.
Where to Use
Automatic Liquid Sampling SystemsSample bite verification for crude oil and liquid hydrocarbon sampling systems that require grab size confirmation and sampler performance monitoring.
Sample Volume VerificationConfirms adjustable sampler volume settings and supports repeatability checks for adjustable or fixed-volume samplers.
Sampling System Overpressure ProtectionProvides remote warning and pressure relief to help protect the sample line from continued overpressurization.
