Multivariable Transmitters (Mass Flow/Multi-sensing)

Multivariable Measurement

Multiple measurements in one devicemultivariable transmitter

Multivariable transmitters simultaneously measure differential pressure, static pressure, and external temperature all in one device. Engineered with mass flow and multi-sensing capabilities, these devices can calculate either compensated mass or volumetric flow rate. They are ideal for use in mass flow and DP flow applications, helping you achieve improved operational efficiency and reduced installation costs.

Yokogawa EJX series transmitters integrate the DPharp multi-sensing capability with an onboard flow computer and can be configured for multivariable (DP, SP, T) or dynamically compensated mass flow outputs.

  • 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.
