pH/ORP Measurement for Reverse Osmosis |
|
Reverse Osmosis is another pure water application where accurate pH measurement and control are the key for assuring reliable membrane performance.
|
|
|
Reverse Osmosis Filter Monitoring |
|
The reverse osmosis (RO) process is used in many industries. This process uses membrane separation which has been proven to be one of the most economical means to remove suspended solids from feed water.

Fully Integrated Modbus Communication Functions on STARDOM PLC/RTU |
|
STARDOM field control node (FCN) autonomous controllers allow both Modbus master and slave functions to run simultaneously.
|
|
|
Integration of Real-time Utility Monitoring with a DCS |
|
The discharge of improperly treated industrial chemicals and fuel gas can have a major impact on the environment, posing a serious threat to public health. Concurrent with the global growth of manufacturing operations to keep pace with market trends, many countries are taking measures to deal with environmental problems.

SCADA-RTU Communications Using GPRS |
|
| To make the most of the advantages of GPRS, Yokogawa's STARDOM FCN/FCJ intelligent RTUs and FAST/TOOLS SCADA package have several functions that reduce the number of packets that must be sent. This dramatically lowers communication fees. |
|
|
Dissolved Oxygen Measurement |
|
When used to measure the dissolved oxygen in an aeration tank, sensors tend to quickly become contaminated and need frequent cleaning. A cost-effective solution to this problem has finally been found with the Yokogawa DO402 Dissolved Oxygen Converter system.
|
|
|
Selection of Sensor Holders for Liquid Analyzers |
|
To reduce the maintenance frequency, measures must be taken to prevent dirt accumulation on the sensor. Our liquid analyzers, DO402/OR400/SS400 can ensure stable and continuous measurement, and reduce the operating costs.
|
|
|
Float Holders |
|
The DO402 dissolved oxygen analyzer system has demonstrated that the sensors could be kept free of heavy dirt accumulation, eliminating the need for maintenance and enabling continuous measurement for long periods of time.
|
|
|
Remote Monitoring of Water Supply and Sewage |
|
By introducing DAQSTATION into your system with its high reliability and wealth of computation and networking functions (Ethernet), you can greatly reduce the labor and costs of monitoring and recording supply pumps at the waterworks.
|
|
|
Measurement Optimization in the Water Industry |
|
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.
|
|
|
Measuring Water Quality |
|
The TB750G can support the application specified as "Constant Turbidity Monitoring at the Outlet of a Leaching Pond" in the "Guidelines in Japan for Provisional Measures against Cryptosporidium in Tap Water".
|
|
|
Screen Differential Control |
Screen differential control and monitoring is needed to prevent damage to rotating screens caused by excessive pressure being applied by debris collecting on the screens.
|
|
|
Autolevel |
|
Level transmitter configuration can be very time consuming. DPharp transmitters with advanced software functionality eliminate this time consuming task. With maintenance shops getting smaller, finding equipment that allows us to do more with less becomes a priority.
|
|
|
Low Flow Cut-off |
|
One of the most common applications for differential pressure transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.
