Fluorescence Digital Dissolved Oxygen Sensor For Thermal Power Plants
The dissolved oxygen analyzer(DO controller and DO sensor) is widely used in industrial applications. For example, in thermal power plants, in order to inhibit the metal corrosion of the system by dissolved oxygen in the water and ensure the safe and economic operation of thermal equipment, the dissolved oxygen content of the outlet water and condensate of the deaerator should be monitored to facilitate Adjust the operating conditions or change the operating mode according to the monitoring results to reduce the dissolved oxygen content to the allowable range.

Factors affect the measurement of dissolved oxygen
1. The water temperature: The higher the water temperature, the lower the solubility of oxygen.
2. Pressure: The solubility of gas is also closely related to atmospheric pressure, so pay attention to compensation for atmospheric pressure.
3. The dissolved salt in the water: At the same temperature, the dissolved oxygen will decrease by about 1% for every 100mg/L increase in salt content.
In addition, the diffusion of oxygen through the solution is faster than the diffusion through the membrane, and the flow rate is too slow to cause interference. Our dissolved oxygen controller has the compensation for air, salinity and temperature.
