The transmitter can be used to display data measured by the sensor, so the user can get the 4-20mA analog output of the transmitter's interface configuration and calibration. And it can make relay control, digital communications, and other functions a reality. Dissolved oxygen is a measure of the amount of gaseous oxygen contained in water. Healthy waters that can support life must contain dissolved oxygen (DO).
What is Dissolved Oxygen (DO)?
Dissolved Oxygen enters the water by:
direct absorption from the atmosphere.
rapid movement from winds, waves, currents, or mechanical aeration.
aquatic plant life photosynthesis as a by-product of the process.

Why Monitor Dissolved Oxygen?
Measuring dissolved oxygen in water and treatment to maintain proper DO levels, are crucial functions in a variety of water treatment applications. While dissolved oxygen is necessary to support life and treatment processes, it can also be detrimental, causing oxidation that damages equipment and compromises products.

Dissolved oxygen affects:
Quality: The DO concentration determines the quality of the source water. Without enough DO, the water turns foul and unhealthy affecting the quality of the environment, drinking water, and other products.
Regulatory Compliance: To comply with regulations, wastewater often needs to have certain concentrations of DO before it can be discharged into a stream, lake, river, or waterway. Healthy waters that can support life must contain dissolved oxygen.
Process Control: DO levels are critical to controlling the biological treatment of wastewater, as well as the bio-filtration phase of drinking water production. In some industrial applications (e.g. power production) any DO is detrimental to steam generation and must be removed and its concentrations must be tightly controlled.
