Automatic Shut-Off Systems For Loading Arms
Virtually any OPW top loader can be equipped with an automatic
shut-off feature to help prevent spillage and overfills that can result when
working with a remote valve.
The automatic shut-off feature allows an operator to load
using multiple arms to make the loading operation more efficient and safer.
Both electrical and pneumatically operated shut-off systems
are available. An adjustable level sensor mounted on the drop tube or vapor
recovery plate works in conjunction with an actuated valve to stop flow when
the predetermined fill level is reached. Electrical systems with multiple
sensing points can be used to trigger a number of actions such as closing
a valve, slowing down a pump, or sounding an alarm.
