Understanding Automatic Weight-Based Dosing Technology
At its core, automatic weight-based dosing is a closed-loop system that measures the actual weight of each laundry load and calculates precise chemical requirements based on soil levels, fabric types, and program parameters. Load cells integrated into the washer drum or support structure continuously monitor weight fluctuations throughout the cycle.
How Load Cells Transform Chemical Delivery
Load cells function as highly sensitive digital scales, detecting weight changes as small as a few grams. When textiles absorb water, the system recalculates and adjusts chemical injection rates in real-time. This dynamic adjustment prevents the common problem of over-dosing during water saturation or under-dosing during final rinse phases.
The Difference Between Volumetric and Gravimetric Systems
Traditional volumetric systems pump chemicals based on time or pump strokes, assuming consistent viscosity and pressure. Gravimetric (weight-based) systems measure mass directly, making them immune to temperature fluctuations, chemical settling, or supply line pressure variations that plague conventional setups.
