Google Tank Level Indicator

A level indicator will not stop an overflow, you need some sort of interlock for that.

Try the top mounted radar level transmitter from Rosemount for fouling applications.

The poster asked for a level indicator not a transmitter, I assumed he was asking for a sight board or magnetic flag type.

Roydm, Am assuming the OP has used the word "level indicator" to mean a transmitter, since he is wanting to enable an inlet line shutdown on LAHH with this device.

We'll probably never know since he hasn't been back.

While I agree radar is a good choice for level I still prefer a bottom mounted DP cell for reliability perhaps with a backup level switch.
Cheers

what you need is LIT, Level Indicator Transmiter, in order to trasmit the signal to the control room asociated to an interlock to stop the flow of entrance of the tank controlling a valve, or stop a pump, depending of your system configuration.
a level indicator do not perform any action to stop the filling of the tank, the level indicator only shows the level of the tank in your control room (depending if it is in field or control room)
