The purpose of this sampler is to provide a safe and efficient method for sampling refined product. This sampling process requires larger volumes per sample than other sampling procedures, necessitating the larger size pumps.

Principle of Operation

A double acting power cylinder is connected to a smaller sampling cylinder pump. As the piston retracts via actuation by the sample signal, product is pulled into the small cylinder. The reverse actuation causes the valve actuator to switch the 3-way valve to allow product to be pumped from the cylinder into the sample container.
