What is a pressure transmitter? They are simple devices based on a simple principle, and we can use them to measure more than pressure, like level and flow. To do this, we need some other devices as well, and the value proposition of a multivariable pressure transmitter is that it replaces all of them.
We can install a pressure transmitter in all kinds of applications, but all of these take different installations. For example, if we want to measure a level with a differential pressure device and if we have an open tank, then we can install the device on the bottom of the tank using a flange with a filled-sealed container.

A multivariable pressure transmitter has the ability to replace multiple other instruments in the plant by measuring multiple pressure variables. Earlier, to measure flow using a differential pressure transmitter, we had to combine elements – differential pressure transmitter, static pressure transmitter, temperature sensor, local indicator, and a computer to collect and calculate everything.
We still can find this sort of solution in the market, and depending on our needs it may be enough, for example, if we already have some of its parts in place. However, it costs more than a multivariable pressure transmitter because it needs more structure, devices, and time to set up.
A multivariable pressure transmitter offers all these features in a single device: differential and static pressure sensors, and an easy way to connect a temperature sensor. The multivariable pressure transmitter will measure mass flow accurately while requiring less structure and time to set up and run.

While multivariable pressure transmitters are great for measuring flow with pressure, it’s worth noting that now there are more specialized flow measurement devices that perform better. For steam measurement, for example, it usually makes more sense to use a vortex flow meter.
