Mass Flow (Multivariable)

A Multi-variable transmitter combines a differential pressure transmitter, a gauge pressure transmitter, a temperature transmitter, and a flow computer into one unit.

The flow computer is programmed with application information and uses the three measured inputs to calculate the Mass Flow.

Like the Volumetric Flow, Mass Flow accuracy is determined by the accuracy entire system. This accuracy not only includes the hardware, but also the accuracy of the process parameters used to program the flow computer.

  • EJX910A

    This transmitter precisely measures differential pressure, static pressure, and process temperature; then uses these values in a high-perfomance on-board flow computer to deliver fully compensated Mass Flow.
