What is “Fill-by-Time (Interval Time)”? | Explained for Packaging Systems
Q1: What is Interval Time Filling?
Interval Time Filling is an automatic filling mode used in packaging machines. The system triggers a filling operation at fixed time intervals (e.g., every 5 seconds) without relying on container detection sensors or manual intervention. It is ideal for production lines with a steady rhythm or semi-automatic workflows.
Q2: How Does This Filling Mode Work?
- The operator sets a time interval (e.g., 2 seconds);
- The system automatically performs a filling operation at each interval;
- Filling occurs regardless of whether a container is in place, which may result in spillage or product waste if not monitored;
- No sensor or manual trigger is required;
- The filling frequency can be easily adjusted to suit different production needs.
? Video Demo: How to Enable Interval Time Mode?
We’ve recorded a video tutorial showing how to enable and use the Interval Time mode on VTOPS auger filling machines:

Highlights in the video include:
- Enabling the mode via the touchscreen interface (HMI);
- Setting various interval times (e.g., 0.1 seconds, 2 seconds);
- Real-machine demos showing different speeds:
- 0.1 second: Appears as continuous filling, similar to rapid-fire mode;
- 2 seconds: Obvious pause between fills, ideal for slow-paced operations.
Q3: What Applications Are Suitable for Interval Time Mode?
✅ Simplified lines without container detection sensors
✅ Semi-automatic setups with manual bottle placement
✅ Drip-filling liquids like disinfectants or pesticides
✅ Uniform-paced, continuous production lines
Q4: How Does It Compare with Other Filling Modes?
| Filling Mode | Description | Precision |
|---|---|---|
| Fill-by-Sensor | Triggers when a container is detected | ✅ Accurate |
| Fill-by-Weight | Stops when target weight is reached | ✅✅ Very Precise |
| Fill-by-Time (Interval Time) | Triggers by time interval | ⚠️ Depends on consistent rhythm |
| Fill-by-Foot Switch | Manually triggered by foot pedal | ✅ Flexible |
Q5: Which Machines Support Interval Time Mode?
At VTOPS, several powder filling machines—such as the VTOPS-P2 Series—already support the Interval Time filling mode. This feature can be configured directly through the HMI (Human-Machine Interface), with the interval adjustable in seconds. It’s a versatile option for small to medium-sized businesses or operations with frequent product changeovers.
Q6: Is Interval Time Filling Right for You?
✅ You want a cost-effective, simplified equipment structure
✅ Your production rhythm is stable or involves manual bottle placement
✅ You don’t require precise bottle detection
Then Interval Time Filling is a high-value automation choice, especially for industries like food, chemicals, agriculture, and personal care where simplicity and timing consistency are essential.
