It measures airflow velocity by averaging multiple pressure readings across the duct cross-section, delivering consistent and repeatable readings without requiring an actuator or differential pressure transmitter. This kit fits 12-inch round damper configurations and supports a velocity range of 400 to 5,000 FPM with an accuracy of 5 percent. It is installed by HVAC technicians and controls contractors as part of air measurement and balancing systems in commercial and industrial mechanical applications.\u003c\/p\u003e\n\u003cp\u003eThis flow probe kit is suited for round duct and damper assemblies where airflow monitoring or control is required. Typical installations include air handling unit supply and return sections, outdoor air intake stations, and VAV system measurement points. The kit ships without an actuator and without a differential pressure transmitter, making it appropriate for applications where those components are sourced or specified separately. Maximum operating temperature is 120 degrees F.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCenter averaging design provides representative velocity measurement across the full duct cross-section\u003c\/li\u003e\n  \u003cli\u003eVelocity range of 400 to 5,000 FPM covers typical commercial HVAC duct velocities\u003c\/li\u003e\n  \u003cli\u003e5 percent accuracy rating for reliable airflow data in balancing and controls applications\u003c\/li\u003e\n  \u003cli\u003e12-inch diameter sizing for direct installation in matching round damper assemblies\u003c\/li\u003e\n  \u003cli\u003eKit ships without actuator and without differential pressure transmitter for flexible system integration\u003c\/li\u003e\n  \u003cli\u003eMaximum operating temperature of 120 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flow measurement component for 12-inch round damper assemblies in commercial HVAC air distribution and controls systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or certified controls contractors. De-energize the air handling system and verify zero airflow before inserting or securing the probe in the damper assembly. Ensure the probe is oriented correctly per manufacturer directional markings to achieve accurate center-averaging readings.
