Anti-overfill Valve

Anti-overfill valve for tank gauging system is installed at the loading pipe between oil truck and underground tank; and between anti-overfill valve and SS160Plus tank gauge console, there is a valve controller. The controller plays a role like a information transmission center which receive the demand from SS160Plus tank gauge console, send shut off demand to specific valve, so to stop oil loading immediately.

When the oil height arrive the alarm value of Oil High (e.g. 90%), the valve can automatically trigger alarm; when the oil height reach to the alarm value of Oil HH (e.g. 95%), it will cut off the loading pipe automatically, so to protect against overfill perfectly.

When SS160plus console send demand to valve controller?

Usually user preset the alarm value of Oil H and Oil HH in console, when the oil level data from SP300 magnetostrictive probe reach to this alarm valve, console will send demand to valve controller instantly. The data transmission speed from probe to console is one time per ms; all demands transmission and cut off will be finished in seconds, much faster than manually operation.
