The SVL100 Digital Stack Velocity Meter is a portable battery operated instrument that can be used to measure Stack Gas Draft Velocity, Stack Temperature and concentrations of CO2 and Oxygen in the flue gas. Optionally a Sensor for CO can also be provided. Unlike several other instruments that measure the Oxygen concentration and calculate the CO2 levels the SVL100 uses dedicated sensors to measure both CO2 and Oxygen.
For better accuracy in Draft measurement the SVL100 Digital Stack Velocity Meter will calculate Stack Gas Density based on measured concentrations of CO2 and Oxygen present in the Flue gas. A filter holder and moisture trap has been provided to protect the sensors from particulates and moisture present in the flue gas.
