Is the measurement of an ultrasonic flow meter related to fluid density? ?

As the title says. Does a change in fluid density affect the flow measurement results?
Liquids have a relatively smaller impact, while gases have a greater one; therefore, when measuring gas flow rates, temperature and pressure compensation is generally required
Changes in density will certainly affect the sound speed of the medium, which in turn has a certain impact on the flow measurement results. It’s just that the density of liquids generally changes little, so this effect is minimal. For reference only.

Personally, I think density must be related to flow rate
An ultrasonic flow meter determines the volumetric flow rate by measuring the fluid velocity; for liquids, it is necessary to measure the mass flow rate. The instrument calculates the mass flow rate by multiplying the volumetric flow rate by a density value set manually. As the temperature of the fluid changes, its density also changes, and relying on a manually set density value does not ensure the accuracy of the mass flow rate measurement.
In my opinion, the measurement of an ultrasonic flow meter has nothing to do with the fluid density! The reason for using ultrasonic flowmeters is to measure flow rate by determining the velocity of the fluid, and any change in the fluid’s density will inevitably affect its velocity; therefore, errors are likely to occur regarding the density value.
