[Constant Vs]
Press the <Right Arrow> to access.
The [Constant Vs] UniMass Table can be used for single liquid applications where
temperature is not constant but measured directly by the flow meter.
●
Create/Edit Table Point
[New Point + Points List (1-32)]
You may Create or Edit up to 32 points. If you need support for multiple liquid classes, you
may create additional identical flow sensing sites to accommodate them, altering only the
UniMass Table entries. Then each site may be called up as needed for each liquid.
●
Temperature F or C
[Temp Value]
This is the temperature of a liquid. In the UniMass table this entry must correlate with a given
Vs (sound velocity).
●
S.G.
[Specific Gravity]
This is the specific gravity of the process liquid at the Vs and Temperature for this table
entry. The specific gravity is defined as the density of the sample divided by the density of
water at 20°C (68°F).
●
Viscosity
[Liquid Viscosity (cS)]
This is the viscosity of the process liquid in centistoke units at the Vs and Temperature for
this table entry.
●
Clear Table
[Yes/No]
Use this item to remove all table points. You will need to re-enter all table data if you answer
[Yes] to this menu item.
●
Table Active
[Yes/No]
Use this item to tell the flow meter whether to use the UniMass Table.
Standard Data Entry Method
Use the following standard data entry methods for Constant Vs and Constant Temperature.
Note
UniMass will not project viscosity and specific gravity measurements beyond the entered
limits of the table but rather keep the highest or lowest table entry as its output.
