Safe and efficient liquid level control

——Wireless monitoring services make work more efficient and safer

In the past, the preferred mode of operation for small oil plants was manual control. Operators needed to repeatedly check the liquid level and pressure gauge in the tank and adjust the valve. Today, all complex procedures, engineers and operators can complete their work more accurately through Human-machine interface (HMI). The EXTER series human-machine interface not only increases the safety and accuracy of the operator's work, but also improves overall work efficiency and reduces costs. The EXETR series human-machine interface has the characteristics of reliability, accuracy and high clarity, and is very easy to install and use. Safety first NTE Automation (NTE) is a supplier of oil tank monitoring services. Their customer Economy Plymer and Chemicals is one of the leaders in polymer technology. Economy contracts with customers to maintain polymer supply at customer locations. NTE needs to ensure that Exonomy's oil tanks around the world maintain effective polymer standards. Before using human-machine interface control, operators at each site had to manually check the liquid level of the oil tank and need to climb up and down to check the oil tank. Today, automation technology simplifies this process. At each tank station, operators use HMIs to control tank levels and maintenance services. Remote monitoring and maintenance systems greatly reduce the risk of employees working dangerously. Perfect combination of hardware and software NTE's unlimited data exchange software is installed on all Beijer HMIs, and the monitors continuously report the level of the tank via the satellite network. The data is transmitted to a central server and can be viewed around the world using a network connection. NTE helps Economy optimize delivery time, logistics arrangements, reduce operating costs, eliminate liquid spills, and ensure that Economy provides the best service to its customers. Demanding requirements for HMIs Embedded display is the most important part of any HMI. When selecting an HMI for the control system, NTE evaluated some of the major HMI brands on the market. Beijer EXTER series HMIs are important for selection due to their ergonomic appearance, high-definition display, stable functionality and easy-to-use configuration tools. Jeff Fish is an automation designer and PLC programmer at NTE . “Beijer Electronics’ EXTER series HMIs are high quality and well designed,” he said. “Beijer’s products combine user-friendly interfaces with high performance. They not only look beautiful, but also have powerful functions. It is our mission to ensure that the products are reliable.” Surprise customers Customer feedback on the EXTER series HMIs has been very good. Some of NTE’s customers have never used touch technology before, and they are very happy to be able to see all the information on the screen. The touch screen simplifies the cumbersome and complex control program, replacing many buttons, lights and other interfaces. If a problem occurs, the screen will give suggestions for solutions. In many cases, customers can solve their problems themselves, which helps NTE save a lot of time and reduce labor costs. Powerful configuration tools NTE will help customers customize their products before shipment, such as setting up customer logos, buttons and other pictures according to requirements, mainly thanks to the easy-to-use Information Designer configuration tool. This configuration tool can develop new functions and develop new applications according to customer needs. For Economy, NTE has designed a flow chart of pipes and valves for them in the touch HMI. NTE has also established many safety settings for automatic alarms. "Information Designer is very easy to use. The character library saves us a lot of time," said Jeff Fish. "For the rest, we only need simple training. If you have experience in HMI operation, it is really easy to switch to Beijer Electronics' configuration tool." New level of security and functionality Since NTE adopted Beijer Electronics' HMI, they have not used other brands of HMI in the past 3 years. "Beijer Electronics' EXTER series HMI adds a lot of value to our products. We provide customers with a new level of security and functional solutions," said Mr. Jeff Fish of NTE. "At the same time, Beijer Electronics' service is also very complete. They will respond quickly to customer requests, and if there are any problems, they will handle them carefully. However, there are really not many problems with Beijer's products."
