4.9.7 Submenu Flow Linearizer Tabular entry
The Flow Linearization algorithm may be used to improve linearity of the flow
measurement. The Flow Linearization table is built during factory calibration pro-
cedure and stored in the device EEPROM. The Flow Linearizer can be used with
both flow measurement algorithms. By default unit shipped from the factory with
enabled Flow Linearizer. A typical display with Flow Linearizer selection is shown
below.
The listed above Flow Linearizer selections can be set with the Up and Dn buttons
and are accepted by pressing ENT button.
4.9.8 Submenu Fluid Density Numerical entry
When the flow is displayed in gravimetric (mass based) units (e.g: g, kg, t, pound)
a density value of the actual fluid must be entered for the flow rate and total cal-
culation. The translation conversion to mass flow is settable between 0.01 and
5.00000 g/cm3. A typical display with Fluid Density selection is shown below.
4.9.9 Submenu Pilot Calibration timer Tabular entry
The Pilot Calibration timer accumulates operational hours since last time unit was
calibrated. The value of the timer may be reset by the user by pressing Ent button.
A typical display with Calibration timer selection is shown below.
