Sounds like the LM-150 is the better option.</div>

Yes I would keep the AC Line voltage (a separate unit on the LM controllers) as most all liquid level meters require power cycling at some point, and the means to do that remotely is beneficial.</div>

I looked around and it seems like only AMI is still producing a liquid level readout, if Lakeshore still has one I couldn't find it on their active products.</div>

The AMI unit is a bit cheaper than the LM-150 however it only has a single I/O connector and has a single 0-10V and 4-20mA output, whereas the LM-510 has 2 of each.</div>

Is AC line voltage output (to control a valve) something that will be needed?</div>
