Hi All,

I have a projects where will be a request to install pig signallers.
Customer who came back to me, asked question:
What is a cheaper/ better device to install: intrusive or non-intrusive pig signallers.

There is not an easy answer on that one.

I'm personally big fan of non-intrusive pig signallers but I will still have to convince my client to go with non-intrusive.

Any thoughts?

Thanks for any advice
