Flow Sciences’ Bulk Powder Weighing Enclosures

LELAND, NC, June 26, 2018 — Weighing powder from a 30-gallon drum? Flow Sciences, Inc. offers Bulk Powder Enclosures that are an effective system for bulk powder applications and large drum loading/unloading. The systems are available in several standard sizes, ranging from 4’ through 8’ exterior width.  A 20” diameter cut-out in the base allows for raising of the powder drum up and into the enclosure. This feature allows for safe weighing without interference stemming from data fluctuation or powder loss.

Bulk Powder Weighing Enclosures are shipped with 3 sizes of rubber membranes which can be cut to adapt to a wide variety of drums. To install, one simply pulls the membrane over the rim of the drum and installs a stainless steel ring to facilitate an air/powder leak-tight seal. Also available is a foot-controlled hydraulic lift (model 6551) which allows for ergonomic lifting of the drum up into the enclosure through the drum cut-out opening.

Results of Factory Acceptance Tests (FAT) and Site Acceptance Testing (SAT) have proven that Bulk Powder Weighing enclosures meet the performance requirements to retain containment below 1 microgram per cubic meter (μg/m³).  For more potent powders, a gloved Bulk Powder Hybrid Isolator is also available.
