The Accumass SF500 is a powerful integrator designed for use with solids flowmeters. Operating with any solids flowmeter with up to two strain gauge load cells or LVDT sensor, it processes sensor signals for accurate flow rate and totalized weight of bulk solids. It can take on lower level control functions traditionally handled by other devices, and it supports digital communications and Fieldbus connections. Its patented load cell balance function eliminates matching of load cells.

The PID function may be used for rate control of pre-feeding devices and/or control of additives with two internal PID controllers. Operating in tandem with two or more solids flowmeters or weigh feeders, the SF500 may be used for ratio blending and controlling additives. Batching, load out and alarm functions are also provided by the SF500.

Milltronics Dolphin Plus software may be used for programming the unit with a PC.
