VARIBOX FC 800 Empty Level Sensor EPDM

Know When Your VARIBOX FC 800 Is Empty

The VARIBOX FC 800 Empty Level Sensor EPDM provides an automatic signal when the liquid inside the container reaches its minimum level. This allows your equipment to recognise when the VARIBOX is virtually empty without relying on manual checks. Installed at the lowest point of the VARIBOX FC 800, the sensor monitors the remaining liquid using an integrated float switch. When the product level drops, the electrical contact changes and sends a signal to the connected system. This signal can be used within your installation, for example to switch off a pump automatically when the VARIBOX is empty. The result is a practical way to integrate container status into your process and reduce the need for manual level monitoring.

Automatic Empty Detection for Your Process

Knowing exactly when a chemical container has reached the end of its usable contents is important for efficient process operation. Without an empty level signal, operators may need to check the container manually or determine its status based on pump behaviour. The VARIBOX Empty Level Sensor provides an electrical indication directly from inside the container. As long as sufficient liquid remains in the VARIBOX, the float stays raised and the electrical circuit remains closed. When the container is emptied, the float drops and the contact opens. Your installation can use this change in signal as part of its own control logic.

Protect Your Pump Against Running Dry

One of the most practical applications of the empty level sensor is automatic pump control. When the VARIBOX FC 800 reaches its empty level, the sensor can provide the signal required by a connected control system to stop the pump. This helps prevent the pump from continuing to operate when there is no longer sufficient product available. The exact response to the signal depends on the design and configuration of the connected installation. This gives equipment designers and operators the flexibility to integrate the VARIBOX empty signal into their own process controls. Instead of treating the IBC as a standalone container, the sensor allows the VARIBOX to communicate its status to the surrounding equipment.

Positioned at the Lowest Point

Accurate empty detection depends on the position of the sensor. The float switch is located at the deepest point of the VARIBOX FC 800 inner container, allowing it to respond when the product level reaches the bottom of the container. At the point where the sensor indicates empty, approximately 1 litre or less of liquid remains, depending on conditions. This low switching level allows the process to use virtually all of the available product before the empty signal is generated. For valuable or hazardous chemicals, making efficient use of the container contents can help reduce both product loss and residual chemical requiring further handling.

EPDM Configuration for the FC 800

This version of the empty level sensor is specifically designed for the EPDM configuration of the VARIBOX FC 800. The sensor incorporates EPDM, PE, PP and PVC materials. Because parts of the sensor are used inside the chemical container, compatibility with the stored product must always be verified. Chemical compatibility depends on factors including the chemical itself, concentration, temperature and operating conditions. A separate Viton version is available for VARIBOX FC 800 applications requiring that configuration.

Connect the VARIBOX to Your Control System

The Empty Level Sensor is designed to become part of a wider control installation rather than simply providing a visual indication. Its connection allows the sensor signal to be transferred from the VARIBOX to external equipment. The corresponding connector components can be used to integrate the signal into your control system. Depending on the installation, the empty signal can be used for functions such as stopping a pump or triggering another predefined process action. This creates an important link between chemical packaging and process automation.

Fail-Safe Level Monitoring

VARIBOX level sensors use a fail-safe electrical principle. The electrical circuit opens when the empty level is reached. It also opens if the sensor cable is damaged. This means a broken cable does not simply continue to produce the same electrical state as a container with sufficient product. The empty level sensor uses a 2-pin connection and is designed specifically for empty detection. It cannot be combined with the VARIBOX low-level sensor in the same configuration. These characteristics make correct installation and integration into the customer’s control system essential.

Supporting Efficient Chemical Handling

The Empty Level Sensor complements the wider VARIBOX principles of Safer, Reusable and Sustainable chemical packaging.

Safer

Automatic level detection reduces the need to manually determine whether product remains inside the VARIBOX. Integrating the signal into process controls can also allow equipment such as pumps to respond automatically when the container reaches its empty level.

Reusable

The sensor forms part of the serviceable VARIBOX FC system. Individual components can be inspected and replaced when required, supporting continued use of the reusable container.

Sustainable

Detecting the empty level close to the lowest point helps make effective use of the product inside the VARIBOX. Low remaining volumes mean less unused chemical is left behind when the container is taken out of service for its next cycle.

Make Your VARIBOX Part of the Process

The VARIBOX FC 800 Empty Level Sensor EPDM adds automatic container status detection to your chemical handling installation. By monitoring the product at the lowest point of the container, the sensor can tell your system when the VARIBOX is virtually empty and enable an appropriate automated response. From stopping a pump to integrating container status into a wider control system, it provides a practical connection between your VARIBOX FC 800 and your process.
