How does a dosing module work?

2025-08-07

A dosing module operates through an integrated system of precision mechanisms to deliver controlled quantities of fluids. Here's how it typically functions:

‌Precise Measurement‌:
It employs sensors (e.g., high-resolution load cells) to continuously monitor the weight of the substance being dispensed. Weight loss per unit time is measured at rapid intervals, enabling real-time calculation of flow rates and ensuring exact dosing volumes 3.

‌Controlled Delivery Mechanism‌:

- For liquids (e.g., SCR reducing agents), it generates a fine atomized spray injected into a process stream (e.g., exhaust flow). This ensures optimal dispersion and reaction efficiency 12.
- For solids/powders, it uses gravimetric or volumetric feeders to regulate material throughput based on weight-loss feedback 3.

‌Automated Regulation‌:
An electronic control unit processes sensor data (e.g., weight differentials, timing signals) and dynamically adjusts dosing parameters. This includes modulating pump speeds, valve openings, or actuator positions to maintain target flow rates 14.

‌Dosing Strategies‌:

- ‌Bolus dosing‌: Instantaneous injection of a set quantity 4.
- ‌Continuous dosing‌: Sustained release via infusion or zero/first-order kinetics, often regulated by predefined intervals or external triggers 4.

‌Self-Adjustment & Optimization‌:
Advanced modules feature adaptive algorithms that recalibrate dosing based on real-time system feedback (e.g., pressure changes, concentration shifts), enhancing accuracy in dynamic environments 23.

This integration of metrology, fluid dynamics, and automation enables reliable chemical addition in applications like SCR systems or industrial batching
