DEFINITIONS
Active excitation
ACT EXC: The active RTD supply current.
Active RTD
The flow element part that senses the fluid flow rate.
Active sense
ACT SEN: The active RTD voltage measurement.
Differential resistance
Delta -R (DR): The flow element signal.
Differential temperature
Delta -T (DT): The difference in temperature between the active and
reference RTDs.
Flow arrow
An indication mark used to properly orient the flow element in relation to the “
fluid flow direction.
Flow transmitter
The portion of the flowmeter that conditions, converts and scales the flow signal.
Ground sense
GND SEN: The ground voltage measurement.
Heater
HTR: The flow element part that heats the active RTD.
Local enclosure
The enclosure attached to the flow element (usually contains the wiring
terminal block).
Orientation Flat
A datum plane used to properly orient the flow element in the fluid conduit.
Range
The flow rate measurement region as defined by the lower and upper limits.
Reference excitation
REF EXC: The reference RTD supply current.
Reference RTD
The flow element part that senses the fluid temperature.
Reference sense
REF SEN: The reference RTD voltage measurement.
Remote enclosure
The enclosure that protects the flow transmitter.
