  • Page 5: General

    E-216-5N-E 2. GENERAL Combined with a flowmeter and a shutoff valve, the batch counter passes a predetermined amount of the process fluid in batching operations. Built around a single chip microprocessor, this versatile, compact, and lightweight counter is designed for ease of operation. It saves time and effort in many processes, such as blending materials, dosing with additives, transferring materials from one tank to another, or shipping from an outlet, at chemical, food, paint plants or elsewhere where streamlined production lines are desired.
