1.2 Product Description
The Welker PP-1, PP-2, PP-3, and PP-F Pitot Probes are designed to create a product loop through a connected sampler or
sampling system.
When the product outlet and return of the unit are connected to a sampler or sampling system, the circulation pump and/or
kinetic energy from flow velocity create a circulation loop, a.k.a. hot loop. When in operation, product circulates through the hot
loop, continually presenting fresh product to the sampler or sampling system, allowing for collection of representative samples.
Welker may custom design the PP-1, PP-2, PP-3, and PP-F to suit the particular application and specifications of each customer.
