What is the seal wire?

It is a type of wire that is used to secure and seal an object, typically for security or tamper-evident purposes.
It is typically a thin, strong wire made from materials such as stainless steel, copper, or brass.
Commonly used in various industries, including transportation, security, and so on.
The thickness and strength of the wire may vary depending on the level of security required, and it may be color-coded or labeled with identifying information.
In the context of fuel dispensers, it is usually attached to a seal or locking mechanism.
And it must be broken or removed in order to access the protected components of the dispenser.
The seal wire is placed through a small hole or loop on the access panel. And it fastened to a corresponding point on the dispenser body.

What is the function?

A seal wire is used as part of the metering system in a fuel dispenser.
The function is to provide a physical barrier against entering the metering system.
Once the seal wire is in place, it is twisted or crimped to create a secure seal that can only be removed by breaking the wire.
In addition to preventing unauthorized access,  can also be used to detect if the dispenser has been tampered with.
Any tampering with these components could compromise the accuracy of fuel measurements or create safety hazards, such as leaking or fire.
If the wire is broken or missing, it indicates that someone has attempted to gain access to the dispenser, and the dispenser should be inspected and possibly repaired before being put back into service.

By using, fuel dispenser owners and operators can ensure that the dispenser remains secure.
The presence of the seal wire indicates that the fuel dispenser has not been tampered with since the last inspection or maintenance check.
Fuel dispensers are complex machines that consist of various mechanical and electronic components, including pumps, meters, valves, and sensors.
These components are critical to the accurate measurement and dispensing of fuel, and any tampering or unauthorized access to them could compromise the safety and accuracy of the dispenser.
