Calculate total volume of liquid in sim

Is there any way to calculate/display the total volume of liquid in the simulation at any given time?

I have multiple liquid sources of varying sizes all pushing liquid into a simulation and another object draining the liquid out.

The animation needs to loop so ideally I would be able to match the total liquid being added to the simulation with the total amount being removed.

Is it simply a case of taking the total number of liquid particles and multiplying it by the grid size?

Yup, that’s it - take the number of liquid particles, multiply it by 8 and then by the volume of a voxel/cell in the Grid rollout.

Note that if the Steps per Frame are low and/or the scene scale is too low, the liquid might compress somewhat, so you might get a lower volume compared to what you calculated.

Cheers!
