Abstract
An apparatus for measuring a hydrocarbon concentration of a gas stream in a line includes at least one sensor for measuring a hydrocarbon concentration, the position of said sensor being set off in relation to the line.
Claims12
An arrangement for measuring a hydrocarbon concentration of a gas flow in a line, comprising:
- at least one hydrocarbon sensor configured to measure a hydrocarbon concentration, the hydrocarbon sensor being arranged in a sensor chamber coupled to the line and being set back in the sensor chamber with respect to the line, the hydrocarbon sensor comprising:
- at least one first temperature sensor;
- at least one second temperature sensor;
- and
- at least one heating element for heating the gas flow arranged between the at least one first temperature sensor and the at least one second temperature sensor.
