The SMV 3000 Smart Multivariable Flow Transmitter combines integrated sensor and microprocessor technologies as well as dynamic flow compensation to produce the most accurate and consistent flow measurement. It comes in three different models -
SMA110 0 to 100 psia 0-1in/ 25 inH2O
SMA125 0 to 750 psia 0-1in / 400 inH2O
SMG170 0 to 3,000 psig 0-1in / 400 inH2O
This smart transmitter measures differential pressure and absolute or gauge pressure from a single sensor and temperature from a standard 100 Ohm Resistance Temperature Detector (RTD) or thermocouple type E, J, or T input signals. In addition, the smart transmitter in its flow calculation also includes compensation of pressure and/or temperature and complex variables such as viscosity, discharge coefficient, thermal expansion factor, velocity of approach factor and gas expansion factor.
