What devices are installed in the fill pipe of underground tanks to automatically stop the flow of product during delivery?

Flow shut-off devices are specifically designed to enhance the safety and operational integrity of underground storage tank (UST) systems during product delivery. They work by detecting when the tank reaches its maximum capacity and automatically halting the flow of fuel or product to prevent overfilling. This is essential not only for compliance with environmental regulations but also to mitigate the risks associated with spills and leaks, which can have serious environmental impacts.

These devices are typically installed in the fill pipe, ensuring that during delivery, any potential overflow is effectively managed and that the tank operates within safe parameters. This technology plays a critical role in maintaining the operational safety of UST systems and protecting both the environment and public health.
