GM9907-L6 / L6D Liquid Filling Controller

Precision liquid filling for food & beverage, chemical and coating industries
The GM9907-L6 (single nozzle) and L6D (dual nozzle) is a dedicated liquid filling controller built for drum, IBC, jerry-can and bottle filling lines. The user interface adapts automatically to single or dual nozzle configuration, with dual-speed filling and feed control for stable, repeatable accuracy across food and beverage, chemical, paint, lubricant and coating applications in South Africa.

VARIANTS

Choose single nozzle (L6) or dual nozzle (L6D) — same controller, adaptive interface

The GM9907 liquid filling controller is available in two configurations. The hardware is identical; the firmware adapts the user interface based on whether one or two filling nozzles are connected. This means a single SKU covers single-line and dual-line filling stations.

Feature GM9907-L6 (single nozzle) GM9907-L6D (dual nozzle)
Filling configuration One nozzle, one fill cycle at a time Two nozzles, independent or simultaneous fill
UI adaptation Single-channel display Dual-channel display with per-nozzle status
Recipe storage Up to 20 recipes for different liquid products Up to 20 recipes per channel
Fill speed control Automatic dual-speed (coarse / fine) fill Per-nozzle dual-speed control
Front-end integration Feed control to pump or supply valve Independent feed control per nozzle
I/O 12 inputs / 16 outputs (shared) 12 inputs / 16 outputs (allocated per nozzle)

How to choose

Choose the L6 for single-station filling lines — manual drum filling, single-head bottling, IBC and jerry-can stations with one filling point.

Choose the L6D for dual-station filling lines — higher throughput, two parallel fill points, or two different products being filled simultaneously.

Typical industries

Food and beverage: syrup, juice concentrate, oils, sauces. Chemicals: solvents, detergents, agrochemicals, acids/bases (specify compatible materials). Paint and coatings: emulsion paint, resins, inks, lubricant oils. The Modbus-TCP interface integrates fill records with batch traceability and ERP.
