Volumetric sampling online for low viscosity liquids
The PEVL sampling cock is used to take a constant volume sample automatically and sequentially of clear or slightly viscous liquid on a transfer line.
The PEVL has a pneumatic control: it is comprised of a body equipped with a sampling chamber, a sampling piston and an actuating cylinder. At each movement of the actuating cylinder, the sampling piston draws from the transfer line a quantity of product corresponding to the volume trapped in the piston’s calibrated recess. When the piston returns to its initial position, the sample is transferred to the sample bottle through the outlet pipe. The sampling chamber is cleaned by simply connecting the cock to the NEP installation or by injecting a sterilising liquid.
