1.3SMV 3000 Smart Multivariable Transmitters

About the Transmitter The SMV 3000 Smart Multivariable Transmitter shown in Figure 1 measures three separate process variables and calculates volumetric or mass flow rate for gases, steam or liquids for output over a 4 to 20 milliampere, two-wire loop. Its general design is based on the field proven technology of our ST 3000 Smart Pressure Transmitter and meets the same high performance standards.

The SMV 3000 transmitter accepts process temperature signals from an external Resistance Temperature Detector (RTD) or any one of several common thermocouple types. Its unique measurement sensor simultaneously handles differential pressure, static pressure, and meter body temperature signals while a separate circuit processes the process temperature input. Note that the static pressure (absolute or gauge) is read from the high pressure side of the meter body.

Using stored equations in conjunction with the multiple process variable inputs, the SMV 3000 calculates a compensated volumetric or mass flow rate output for gases, liquids and steam. Its output signal is proportional to the calculated differential flow rate.
