Quick answer
A DWS system (Dimensioning, Weighing, and Scanning) is an automated data capture solution that measures a parcel's dimensions, records its weight, and reads its barcode in a single pass — replacing manual spot-checks with certified, real-time freight data. Emerdis deploys both Static and Inline DWS configurations, eliminating carrier billing leakage, induction bottlenecks, and WMS data gaps across fulfilment, 3PL, and postal operations.
INDUSTRY CHALLENGES
Why Manual Parcel Measurement is Costing You More Than You Think
Every parcel that passes through your facility without verified dimensional data is a risk. Under-declared dimensions mean under-charged freight. Inaccurate weights corrupt carrier billing reconciliation. Poor-quality scan data creates downstream errors in your WMS and TMS — errors that compound across thousands of parcels per shift.
For most operators, the problem isn't visible until it hits the P&L.
01
Revenue Leakage
Under-declared parcel dimensions pass undetected through manual checkpoints. The carrier charges you less than the freight actually costs — or you absorb the difference on outbound shipments. Either way, margin drains quietly, shift by shift.
02
Induction Bottlenecks
Manual spot-checks create hard stops at your busiest induction points. One operative, one scale, one barcode scanner — it can't keep pace with modern sortation speeds. The downstream conveyor slows. Your SLAs suffer.
03
WMS & TMS Data Gaps
Poor parcel profiles fed into your Warehouse and Transportation Management Systems propagate errors across billing, routing, and compliance. Without a reliable data layer, you're making operational decisions on guesswork.

DWS System
What is a DWS System and How Does It Work?
A DWS system automates the three most critical data points on every parcel: its physical dimensions (length × width × height), its weight, and its barcode identity — captured simultaneously, in a single pass, at line speed.
The output is a certified, legal-for-trade parcel profile that feeds directly into your WMS, TMS, or carrier billing system in real time. No manual data entry. No spot-check delays. No disputed invoices. Emerdis configures deployments around your throughput — static at induction, or inline on existing conveyor infrastructure.

Emerdis DWS Solutions: Static and Inline
Not all DWS deployments look the same. Emerdis offers two proven configurations, selected based on your throughput volumes, conveyor infrastructure, and operational footprint.
Static DWS — Precision at the Induction
Point
The Static DWS unit sits at a fixed induction station, capturing dimensional, weight, and scan data as each parcel is presented. It's the right choice for operations that need certified data capture without full conveyor integration.
Best suited for
-
Inbound goods receiving and SKU dimensioning
-
Facilities processing mixed parcel profiles
-
Manual induction workflows needing a data layer
Key attributes
-
High-accuracy dimensional capture (±2mm)
-
Legal-for-trade weight verification
-
Instant barcode / 2D code reading
-
Real-time WMS data push
Inline DWS — Continuous Capture at Full Line Speed
The Inline DWS system integrates directly onto your existing conveyor line, capturing data on every parcel without breaking flow. Emerdis executes inline installations as brownfield retrofits, matched to running sorter infeeds, without downtime.
Best suited for
-
High-volume parcel hubs and 3PL sortation centres
-
Automated or semi-automated outbound conveyor lines
-
Facilities where manual induction caps throughput
Key attributes
-
High-speed capture at full conveyor line speed
-
Zero operational disruption during installation
-
Direct WMS, TMS and sorting control integration
-
Continuous audit trail for billing reconciliation

Case Study
Proven in the Field: How Ultima DWS Eliminated Revenue Leakage at a UK Parcel Hub
The Challenge
A UK parcel operator was facing a problem it couldn't fully see. Under-declared parcel dimensions and inaccurate weights were passing through unmonitored sorting segments — creating steady, compounding revenue leakage that only became visible during carrier billing reconciliation. Manual spot-checks at induction had become a bottleneck, and poor-quality parcel data was corrupting the facility's WMS and TMS.
The Emerdis Approach
Emerdis deployed the Ultima DWS system — a compact, industrial-grade dimensioning, weighing, and scanning solution built for high-volume parcel environments. Our engineering and IT teams executed a brownfield retrofit: embedding the Ultima frame onto existing conveyor infrastructure and integrating real-time data into the active WMS, TMS, and sorting control layers — without a single hour of disruption.
The Results
Revenue leakage eliminated
Certified dimensional and weight data on every parcel stopped profit drain from under-declared freight.
Induction bottlenecks cleared
Continuous inline scanning removed manual touchpoints, restoring downstream sortation speed.
Full network visibility
Executive teams gained an auditable, real-time data trail across all parcel exceptions and profile anomalies.
Expert Insight
"The operators we work with don't realise how much they're losing until we show them the data. A 3–5% dimensional error rate across 10,000 daily parcels isn't a rounding error — it's a six-figure annual billing gap. DWS doesn't just fix a measurement problem. It gives you the data infrastructure to run a tighter, more defensible operation."

FAQs
People Also Ask
What does DWS stand for?
DWS stands for Dimensioning, Weighing, and Scanning. A DWS system automates the capture of a parcel's physical dimensions, weight, and barcode data in a single pass, replacing manual measurement and delivering certified parcel profiles to your WMS and TMS in real time.
What is the difference between Static and Inline DWS?
A Static DWS system is installed at a fixed induction station where parcels are individually presented for measurement. An Inline DWS system integrates directly onto a conveyor line, capturing data continuously at full operational speed without any manual touchpoint or break in flow.
Can a DWS system integrate with our existing WMS?
Yes. Emerdis DWS deployments are engineered to feed certified parcel data directly into your existing Warehouse Management System, Transportation Management System, and automated sorting control layers — without requiring a platform replacement.
What is dimensional weight and why does it matter for billing?
Dimensional weight (also called volumetric weight) is a pricing method used by carriers that factors in a parcel's size as well as its actual weight. When parcel dimensions are inaccurate or under-declared, the carrier charge doesn't reflect the true freight cost — creating billing variances that erode margin on every shipment.
What does "legal-for-trade certified" mean for DWS?
Legal-for-trade certification means the DWS system's weight measurements meet the regulatory standards required for commercial billing and compliance — giving you an auditable data trail that holds up in carrier disputes and regulatory checks.
How long does a DWS installation take?
Installation timelines vary by system type and facility configuration. Brownfield inline retrofits — such as the Ultima deployment described in our case study — can be completed without operational downtime. Contact Emerdis for a site-specific timeline.
Is DWS suitable for small-to-medium e-commerce operations?
Yes. Emerdis offers DWS configurations scaled to a range of throughput volumes. Static DWS units are particularly well-suited to growing e-commerce operations that need certified parcel data without full conveyor automation.
