Transducer Block
4.4 Transducer Block
The Transducer Block contains the actual flow measurement data. The data include
information about sensor type, engineering units, digital filter settings, damping, and
diagnostics.
4.4.1 Process Variables (PV)
PV value
PV Value is the actual measured flow rate in the line. On the bench, the value should be
zero. Check the units of the value to make sure they are configured correctly. The unit
configuration is contained in the AI block.
Sensor serial number
This parameter can be entered by the user to be the serial number of the unit or any other
number they would like to insert.
Sensor range
The Sensor Range is the entire flow range of the vortex meter. This includes the range that is
out of the accuracy specification. If the range is between the PV Range and the Sensor
Range, the status of the value is UNCERTAIN. If the Sensor Range is exceeded, the status
goes to BAD and OUT OF SERVICE.
PV range
The PV Range is the range of the flowmeter that can be met with stated accuracy.
4.4.2 Basic setup
Pipe I.D.
The Pipe I.D. (inside diameter) of the pipe adjacent to the flowmeter (mating pipe) can
cause entrance effects that may alter flowmeter readings. You must specify the exact inside
diameter of the pipe to correct for these effects. Enter the appropriate value for this
variable.
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)
