Description

The Heat Flow Rate Sensor block represents an ideal heat flow meter, that is, a device that converts a heat flow passing through the meter into a control signal proportional to this flow.

Connect this sensor in series with the block where you want to measure the heat flow because heat flow is a Through variable (for the thermal domain). Connecting the sensor in parallel may affect the simulation results because it is analogous to adding a bypass connection line between the connection points. A series connection within an existing line does not affect the simulation results and provides an accurate measurement.

Connections A and B are thermal conserving ports. Port H is a physical signal port that outputs the heat flow value.

The block positive direction is from port A to port B.

Ports

Output

H — Heat flow rate measurement, W

physical signal

Physical signal output port for heat flow measurement.

Programmatic Use

Port: H

Conserving

A — Sensor inlet

thermal

Thermal conserving port. The measurement is positive when the value at port A is greater than the value at port B.

Programmatic Use

Port: A

B — Sensor outlet

thermal

Thermal conserving port. The measurement is positive when the value at port A is greater than the value at port B.

Programmatic Use

Port: B

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"fl_lib/Thermal/Thermal Sensors/Heat Flow Rate Sensor"

Example: add_block("fl_lib/Thermal/Thermal Sensors/Heat Flow Rate Sensor","myModel/myBlock",MakeNameUnique="on")

For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
