音叉料位计
The Soliphant M FTM50 is a rugged vibronic point level switch for fine solids or low-density, loose bulk powders in silos. It is widely applicable and has international approval for hazardous-area applications with dust and flammable gases. Available options include a polished fork, clamp process connection, stainless steel or aluminum housing and coated fork. The instrument is maintenance-free; typical applications include grain, flour, cocoa beans, sugar, animal feed, dye powder, chalk, etc.
