Read more on page 20 Instrumentation Focus The Model DB damaged belt detector from Conveyor Components Co. is an economical and effective means of protection for valuable conveyor belts. Read more on page 23 MaxxFlow Flow Meter The MaxxFlow is designed to measure medium to high flow rates (10–600 tn/hr) of powders, pellets, and granules. In the past, only complex mechanical systems like impact flow meters and weigh feeders were possible. Advanced technology in electromagnetic velocity measurement and microwave concentration has produced an open cross-sectional spool piece less than 12 in. long. This meter can fit anywhere in your process under free-fall or sliding conditions with no straight run requirements. The system is ideal for truck and railcar load outs or process measurements after rotary valves, screw feeders, bucket elevators, air chutes, etc. The accuracy is +/- 1-3%, with repeatability to .2%.

Each analysis station is upgradeable from mes- opore to micropore with its own transducers for current or future high-throughput needs. A single 3Flex with its minimal footprint and three configurable analysis stations eliminates costly investment in multiple instruments and additional bench space. Micropore ports include krypton capability for low surface area materials. A vapor option is also available.
