Level and dinsity measurement

You need two outputs to report the results of the two inputs. That sounds like two sensors to me.

What I meant was if single device existed giving "dual output", analog or digital, so there is less mechanical work involved when installing it. Name of a manufacturer would be great.

Because you want to measure density, you will have to use two sensors.

Most density set-ups (eg Rosemount, Yokogawa) have a hydrostatic pressure transmitter at the bottom of the tank and either another on the tank side higher up, or a level gauge (capacitive, servo, radar, whatever) on the tank top.

Level and temperature is common as a single transmitter setup - but not level and density.
