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.
Automatic Liquid Sampling Systems
Sample bite verification for crude oil and liquid hydrocarbon sampling systems that require grab size confirmation and sampler performance monitoring.
Sample Volume Verification
Confirms adjustable sampler volume settings and supports repeatability checks for adjustable or fixed-volume samplers.
Sampling System Overpressure Protection
Provides remote warning and pressure relief to help protect the sample line from continued overpressurization.
Complies With:
Resources
Quick-Connect Outlet Connection With Tubing
Allows operators to conveniently verify sample grab size from one location.
Outlet Check Valve
Helps eliminate drips between pulses for cleaner sample grab validation and more distinct sample counting.
Pressure Switch With Externally Adjustable Relief Valve
Provides remote warning of overpressurization and relieves excess sample line pressure to help protect the sampling system.
Modular Design With Two Panel Configurations
Supports easy mounting and system integration for new automatic samplers or upgrades to existing systems.
