The DO30G sensor for dissolved oxygen is designed for use in water treatment plants such as sewage treatment works, effluent activated sludge process, and potable water treatment. It is also effective in river monitoring, intake protection, fish farming and other fields where water quality is important.
This galvanic cell has a fast response time and good long term stability, and features replaceable diaphragm and cable for easy maintenance. A temperature sensor is incorporated for compensation. The DO30G sensor can be used in either the floating ball fitting or in the immersion fitting.
Features
- Fast response time
- Good long term stability
- Easy membrane change

PB350G/PB360G Floating Ball
The floating ball holder for the DO30 features a design that minimizes fouling in the process. A brass ring around the sensor facilitates a check for membrane integrity and helps to eliminate any deposits of algae, making a cleaning system unnecessary. Maintenance is straightforward, with only periodic inspection and calibration needed.
Features
- Easy to install
- Easy calibration
- Sensor diagnosis for membrane integrity
FD30/PH8HG/DOX8HS Immersion Adapter
The immersion fitting is designed for installing the DO30G sensor in tanks, open vessels, and drains. It can be supplied in lengths between 0.5 and 2.0 meters. Flange mounting is also possible. In applications with a heavy load of solids, a cleaning system is recommended. An optional, "jet cleaner" is available for the immersion fitting. The use of this device can extend the continuous measurement period and eases maintenance.
Features
- Various immersion depths
- Flange mounting possible
- Cleaner option
- Sensor diagnosis for membrane integrity

The control of the world's water resource is arguably one of the most important issues. Water demand from industry and domestic users is set to rise throughout the industrialized world. Yokogawa has been applying minimized maintenance measurement systems.
In a batch tank, analyzers such as dissolved oxygen (DO) analyzers, oxidation-reduction potential (ORP) meters, and mixed liquor suspended solid (MLSS) analyzers are used. To reduce the maintenance frequency, measures must be taken to prevent dirt accumulation on the sensor. As the liquid level in a tank can vary greatly, great care should be taken when selecting the sensor installation position in a tank.
When used to measure the dissolved oxygen in an aeration tank, sensors tend to quickly become contaminated and need frequent cleaning.
Removal of free oil and grease from a wastewater stream reduces the potential for equipment problems to occur further downstream. There are three forms of oil encountered in wastewater treatment at a refinery.
