Page 8: Installation
Air flow / Air velocity-FDM06-P Pitot Tube Thermal Mass Flowmeter IV. Installation The installation method and conditions of the wind speed sensor will directly affect its measurement accuracy and stability. To ensure optimal performance, be sure to follow these recommendations: 1. - Page 9 Air flow / Air velocity-FDM06-P Pitot Tube Thermal Mass Flowmeter 2. Keep away from heat or cold sources Because thermal mass wind speed sensors are extremely sensitive to temperature, they should be installed away from equipment that produces significant thermal effects (such as electric heaters, air conditioning vents, etc.).
- Page 10 Air flow / Air velocity-FDM06-P Pitot Tube Thermal Mass Flowmeter 4. Gas Condition Effects and Scaler Factor Thermal mass sensors calculate flow rate based on the thermal conductivity and specific heat capacity of the gas. Therefore, when the measured gas is different from the calibration conditions, the thermal mass sensor will calculate a different flow rate.
- Page 11 Air flow / Air velocity-FDM06-P Pitot Tube Thermal Mass Flowmeter 5. Flow volumetric rate calculation and profile factor When the gas passes through the duct, the viscosity between the gas and the duct wall causes the wind speed near the wall to be zero (No-slip condition). As the distance from the duct wall increases, the wind speed gradually increases and reaches the maximum value at the center of the cross section.
