H2O compensated flue gas meters are specially designed to measure and compensate for the amount of water vapor in the flue gases, while traditional flue gas meters do not do this.
This makes H2O compensated meters more accurate in their measurements, because the water vapor in the flue gases can influence the amount of oxygen in the flue gases. This can lead to an incorrect measurement of the amount of carbon monoxide and other harmful substances in the flue gases.
H2O compensated meters compensate for this variation, providing a more precise measurement of the amount of harmful substances emitted by the boiler.
The way in which an H2O compensated flue gas meter compensates for the amount of water vapor depends on the specific type of meter. However, there are some common methods that are used.
One of the most common methods is to use a second sensor in the meter to measure the amount of water vapor in the flue gases. This sensor can, for example, be an rh sensor (relative humidity sensor). The measurement from this sensor is then used to correct the amount of oxygen in the flue gases, providing a more accurate measurement of the amount of harmful substances in the flue gases.
Other methods may include: using a pressure sensor to measure the pressure of the flue gas and thus calculate the amount of water vapor, or using a temperature sensor to measure the temperature of the flue gas and thus calculate the amount of water vapor.
It is important to know that the precision of the compensation depends on the accuracy of the sensors used and the precision of the compensation algorithms designed by the manufacturer.
There are many different brands of flue gas meters available, depending on where you are looking. Here are some examples of well-known brands:
This is not a complete list, and there are many more brands available. It is important to research which brand best suits your specific needs and whether the brand has a good reputation for accuracy and reliability.
