Volumetric screw feeders for metered dispensing
Scaletron’s Model VMF-28 volumetric screw feeders are designed for metered dispensing of powdered or pelletized chemicals into water, wastewater, and chemical treatment processes. The Model VMF-28 auger-style feeders feature a fully integrated Scaletron scale. Precise dosage amounts are automatically weighed
and added to treatment processes without requiring an operator to measure
and weigh amounts. Data is displayed at a central monitoring station where
operators can quickly make adjustments as necessary from the control panel. Heat, moisture and other environmental variables can cause additives like lime and carbon to absorb or dissipate water which changes the compound’s weight.
The integrated scale employs four load cells each with an adjustable stainless steel leveling bolt. The scale measures changes in volume to 0.5% accuracy. Controls are housed in a NEMA 4X, UL-approved enclosure. The VMF-28 models are compatible with Scaletron’s line of scale indicators and controllers. These include the Model 1020 5 Digit Controller and Model 1020-B 5 Digit Batching Controller V5 which are programmable units that monitor and automate dosing and dispensing processes.
