Siemens SITRANS WF340 LVDT-Based Solids Flowmeter: 0.2 to 300 TPH

Siemens SITRANS WF340 is a low- to medium-capacity solids flowmeter for various product sizes, densities, and fluidities, particularly for fine powders. It uses a robust linear variable differential transformer (LVDT) to convert the motion of the solid into an electrical signal with great precision, sensitivity, and repeatability. It's typically used in fly-ash load out, lime dosing, and gypsum flow applications.

Dry bulk solids enter the flow guide producing a mechanical deflection as they strike the flowmeter sensing plate before continuing through the process. the LVDT in the SITRANS WFS series sensing head converts the deflection of the horizontal force into an electrical signal that feeds into an accompanying integrator (Milltronics SF500) to display the flow rate and totalize the weight.

A complete solids flowmeter system consists of the SITRANS WF340 flowmeter, a SITRANS WFS300 or WFS320 sensing element, a SITRANS flowmeter sensing plate, and a Milltronics SF500 integrator.
