Anemometer
The thermal flow sensor measures the flow rate and temperature of air and gases and has a limited-range signal output, with an LED display showing the sensor's operating status. It features a compact design, fast single-hole mounting, and flow measurement that does not require pressure and temperature correction. It can be used for combustion gas control, gas measurement in drying systems, etc.
Overview
Applications
Specifications
The thermal flow sensor measures the flow rate and temperature of air and gases and has a linear signal output. An LED displays the sensor's operating status (normal or error). The compact plug-in sensor is installed in the air duct and features a highly accurate probe.
◆Fast single-hole installation
◆Flow measurement requires no pressure and temperature correction
◆Low pressure loss
◆Compact design
◆Probe tube length up to 500mm
Air duct flow measurement, volumetric flow measurement, combustion gas control (e.g., oil, carbon, wood, or combustion gases), gas measurement in drying systems
