Temperature Pressure & Velocity Integrated Monitor
Descriptions
The temperature pressure & velocity integrated monitor is based on pitot differential pressure velocity measurement principle. During measurement, insert the probe of pitot tube into pipeline and make the direction of probe dynamic hole face the flow direction directly and static hole back to the flow direction. Transfer dynamic pressure and static pressure to pressure transmitter respectively and then calculate velocity value according to formula.
When measuring differential pressure, differential pressure transmitter is required to measure both dynamic pressure and static pressure. Thus, special attention shall be paid to the direction of pitot tube during installation, making sure both pressure-acquiring ports are consistent with the flow direction of flue gas (dynamic pressure measurement port is required to align with coming direction of flue gas while static pressure measurement port aligns with the departure direction of flue gas). There are two installation methods, vertical type and horizontal type, as shown in the following figure.
