Backup safety shutoff control
Overfilling an asphalt tank can create a big mess and require a lot of cleanup effort. Tank gauge boards, radar level systems and/or level systems using pressure transmitters are normally setup to prevent overfilling a tank. They are wired into circuits that shutoff the unloading pump when the tank is full. But these can fail unexpectedly, especially if they are not properly maintained.
Our backup system uses a highly reliable float with proximity switch to shut off the pump in case the other device fails. It is included on every asphalt storage tank and will pay for itself by preventing overfills and eliminating their cleanup costs. For payback you only need to prevent a single overfill.
