The transmitter can be used to display data measured by the sensor, so the user can get the 4-20mA analog output by transmitter's interface configuration and calibration. And it can make relay control, digital communications, and other functions a reality.
The product is widely used in sewage plant, water plant, water station, surface water, farming, industry and other fields.
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).
Dissolved Oxygen enters 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.
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 product. Dissolved oxygen affects:
Quality: The DO concentration determines the quality of source water. Without enough DO, water turns foul and unhealthy affecting the quality of the environment, drinking water and other products.
