Process fluid
The flowmeter can be used for liquid or gas applications, but it must be configured
specifically for the application. The standard flow meter can be configured for a liquid
process fluid or a gas process fluid which includes steam. The MTA model which is capable of
measuring process fluid temperature can also be configured for temperature compensated
saturated steam. This model is capable of dynamically calculating the density of the
saturated steam process fluid and using that density in mass flow measurements. If the
flowmeter is not configured for the proper process fluid, readings will be inaccurate. Select
the proper Process Fluid for your application:
Liquid
Gas/Steam
Temperature compensated saturated steam (MTA model only)
Reference K-Factor
The Reference K-factor is a calibration number assigned at the factory. It is located on the
meter body tag. It should only be changed if the meter body is replaced.
Installation effects
Installation Effects enables you to compensate the flowmeter for installation effects. See
reference graphs located in Technical Data Sheet (document number 00816-0100-3250)
for the percent of K-factor shift based on entrance effects of upstream disturbances. This
value can be set between +1.5% to -1.5%.
Compensated K-factor
The Compensated K-factor is based on the reference K-factor as compensated for the given
process temperature, wetted materials, body number and pipe I.D. Compensated K-factor
is an informational variable that is calculated by the electronics of your flowmeter.
Meter body number
The Meter Body Number is a factory set configuration variable that stores the body number
of your particular flowmeter and the type of construction. The meter body number is found
to the right of the body number on the meter body tag, which is attached to the support
tube of the meter body.
The format of this variable is a number followed by an alpha numeric character. The number
designates the body number. The alpha numeric character designates the meter body type.
There are three options for the alpha numeric character:
1. None – Indicates welded meter construction
2. A – Indicates welded meter construction
3. B – Indicates cast construction
Process temperature
Process Temperature and Temperature Units are needed for the electronics to compensate
for thermal expansion of the flowmeter as the process temperature differs from the
reference temperature. Process temperature is the temperature of the liquid or gas/steam
in the line during flowmeter operation.
