: Low alarm outputs 3.8 mA & high alarm can output
K-Factor linearity:
The VT-222 provides 2 to 5
points of K-Factor linearity correction.
Local adjustments:
Setting range and PV units, Density, Flow mode, damping, high alarm percent, low alarm
percent and data recovery etc.
LCD display:
Line 1 shows the instantaneous flow. Line 2 shows the totalized flow. Line 3 can display the
percentage, output current, temperature, pressure, density and more combinations easily selected by the user.
Multivariable Operation:
The VT-222 supports real-time temperature and pressure compensation for gas, and
utilizes the international standard for the steam and density tables for temperature and pressure compensation as well
for superheated steam with pressure compensation or temperature compensation for saturated steam.
Temperature trim:
High trim and low trim .
Pressure trim:
High trim and low trim .
The VT-222 provides power-down protection and flow totalizer value storage functions.
Hardware
