1.2 Product Description
The Welker
LS-14
Constant Pressure Sample Container is designed to collect, retain, and mix large volumes of representative
composite sample.
The LS-14 can be integrated into a system with a pneumatically driven sample pump that interfaces with a Programmable Logic
Controller (PLC) or other signal control system for proportional to flow or timed collection of sample grabs. Product level can be
visually verified on site by referring to the volume indicator with tracker magnet on the LS-14.
Engineered features ensure that the sample is retained and representative for laboratory analysis. The connected inert gas supply
applies and maintains constant pressure on the sample in the LS-14 to prevent vaporization and the escape of entrained gases.
An operator can manually actuate the mixing plate in the LS-14 to thoroughly mix the sample prior to transfer to a transportable
container for laboratory analysis.
Optional equipment can be added to enable remote operation: a controller to take samples automatically, an electro-hyrdaulic
supply to drive the incorporated sample pump, a magnetostrictive level indicator to communicate product level to the PLC, and
a proximity switch to signal the PLC once the desired volume of sample has been collected.
For this manual, the term "PLC," or Programmable Logic Controller, will be used to refer to the PLC, DCS, or other signal control
system used by the customer to activate and operate the solenoid.
Welker may custom design the LS-14 to suit the particular application and specifications of each customer.
