Most LP tanks require Hall Effect

Some are.  Others are hall effect sensors which need 5v and output a voltage.

I've had some customers hook up the output of these to a voltmeter or shunt input with reasonable results.  What I've had in the queue is a module set up specifically for these sensors and which reports percent directly.

    It it not just a 0-200ohm sensor?

    Holy cow, it looks like I should get around to finishing up the
    $59+sensor ($50ish) add-on module for the sitemonitor system....

    Didn't realize these were so expensive.

        This is what you are looking for. We have 4 of them and love
        them.

        Generac 7005 Propane Tank (LP) Fuel Level Monitor - WiFi
        enabled
        https://www.amazon.com/dp/B072KJBLV2/ref=cm_sw_r_cp_api_i_cqtsCbZ22K84X

        The only down side is it has to connect to a 2.4ghz SSID with
        no security enabled.  So we engineered the WiFi AP to only
        accept that MAC address and only hand out 1 ip to that device
        and then fire walled everything so the monitor could only
        talk to their cloud.  Basically the device has a battery in
        it and it turns on once a day for a minute and pushes its
        data to the cloud so you can access it on their free AP or
        website.

            What solutions exist to monitor propane tank levels
            remotely? I've got an off-grid site with three 100 gallon
            tanks. The propane guy setup the manifold such that the
            tanks should drain sequentially, but I'd like to
            monitoring/chart them remotely. Each tank has a R3D
            gauge, but not sure what sensor to plug into them.
