Patent ID: 10507411

Abstract:
A device to extract a near continuous stream of sample water from a high solids content source for the purpose of delivery to a liquid analyzer or sensor for test or measurement. The device includes a source of compressed air and a source of chemical cleaning agent that are used in a coordinated effort to purge and clean the sampling system to ensure the water stream is maintained over long periods of time without significant human intervention. The device includes a valve to allow compressed air to intermittently be sent backwards through the sampling line to purge to drain an inline strainer of solids that have built up since the previous air purge. Downstream of the air valve another valve is used to introduce cleaning chemical into the sampling system to clean residual buildup downstream of the inline strainer. A debubbler unit is placed between the air valve and the cleaning chemical valve to remove air from the sampling system after it was introduced during the air purge event.
