Normal Cubic Meter per Hour
Resistance Temperature Detector
Definitions
The flow element part that senses the fluid flow rate.
The difference in resistance between the active and reference RTDs.
Delta-R (ΔR)
The difference in temperature between the active and reference RTDs.
Delta-T (ΔT)
The portion of the flow meter that conditions, converts and scales the flow signal.
The flow element part that heats the active RTD.
The enclosure attached to the flow element (usually contains the wiring
terminal block).
A flat part on the sensor head that helps to orient the sensor head to the flow.
The flow element part that senses the fluid temperature.
The enclosure that houses the flow transmitter remotely from the sensor head.
A sensor whose resistance changes proportionally to temperature changes.
Detector (RTD)
An adjustment that sets the transmitter's flow rate output range.
Also, the difference between the upper and lower flow rate values.
The flow element part that protects the heater and RTDs from the process fluid.
The ratio of minimum flow rate to maximum flow rate.
An adjustment that sets the flow transmitter's output at zero flow.
