Endress+Hauser recently supplied a mine in the Western Cape with an innovative cost-effective solution to monitor discharged effluent. The solution has been provided as an added value service, and is reported to have resulted in large savings for the mine.
The complete package provided consists of a Prosonic FMU90 ultrasonic open channel flowmeter, and a Minilog used for data capturing. The system was designed to use solar power. This solution has met the challenge of supplying power to instrumentation in a remote area, without incurring the substantial costs of laying power lines.
“This project has demonstrated Endress+Hauser’s continuous commitment to supplying our customers with solutions that are both cost-effective, and ideally suited to the application, and is just one of the reasons why we are top of our game,” says Danie Wentzel project engineer, Endress+Hauser.
The FMU90 uses ultrasonic waves to monitor levels in a channel with a point of restricted flow. The technology works by measuring the build up of fluid behind the point of restriction, and calculates the rate of flow based on programmable tables which equate level with flow. This provides a cost-effective solution to flow measurement, in the absence of pipelines. The FMU90 is suitable for a number of different industry applications, including water treatment plants and food and beverage applications.
The Minilog, which is connected to the FMU90, records the flow measurement data generated by the instrument. This data is downloaded weekly, by connecting the device to a laptop through a USB connection. The data can be used for reporting to the environmental council.
“Due to the success of this project, and versatile range of applications for this solution, we will be adding this solution to our product range in the near future. It makes sense, as it is a reliable cost-effective answer to what would otherwise be a very costly problem,” says Danie.
