Avoiding regulatory fines through redundant water temperature monitoring is crucial for many industrial plants, by commonly extracting water from local outlets like nearby rivers, and employing it for cooling, water purification, and steam for power generation.
Often, the plant recycles the water and returns it to the source. Not only must the water be free from pollutants, but its temperature must also be within an acceptable range based on ambient conditions.
To comply with regulations, companies must monitor and record the recycled water temperature. Companies violating regulations or missing data are subject to fines for each infraction. Since data is recorded every hour, penalties can add up quickly.
Challenges
Holding ponds are often far from the plant process and can be expensive to monitor. Many wireless solutions are available, but they must be selected carefully. Some point-to-point systems are not sufficiently reliable. A wireless gateway could be a single point of failure in systems with many measurements.
In one case, a U.S. chemical manufacturer was subject to fines due to the failure of an existing temperature monitoring system. The company incurred a $100 fine every hour for 50 monitoring points.
Solution
After facing significant fines, the chemical manufacturer needed more reliable monitoring and recording. The engineering team selected Yokogawa’s XS550 Sushi Temperature Sensor due to its cost-effective, reliable long-range wireless communication. To boost the solution’s reliability and availability further, the manufacturer configured the network with redundant gateways.
The low power-consuming Sushi sensor provides long battery life. With temperature-sensing every hour at ponds and river outlets, the light load on the sensor batteries offers the chemical manufacturer a potential 10-year battery life. That translates to low maintenance. Because the Sushi sensor can transmit data over a long-range via the LoRaWAN protocol, the solution does not require data repeaters. That eliminates another potential source of failure. Since the sensor is plug-and-play and often arrives with factory-installed configuration, installation is simplified.
For this chemical manufacturer, Yokogawa’s GA10 Data Logging Software rounds out the self-contained solution to meet EPA regulations for effluent discharge. Since this fully on-premise solution can be isolated from the control room, there is no concern about losing the connection to the process control system or missing data.
Key Advantages
- The Sushi sensor’s low power consumption results in extended battery life and significantly reduced maintenance expenses.
- The Sushi sensor offers seamless, simple integration with a wide range of host systems through an industry-proven communication platform.
- Improved measurement availability with gateway redundancy enables the manufacturer to comply with regulations and avoid fines.
Industries

Chemical
Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
