Application of Sonar Flow Meters for Long-Distance Transportation of Benxi Nanfen Iron Ore Concentrate

Application of Sonar Flow Meters for Long-Distance Transportation of Benxi Nanfen Iron Ore Concentrate

The concentrate‑powder pipeline transportation project at the Nanfen Concentrator of Benxi Mining has been put into operation. The project comprises a concentrate pump station at the upstream end, a filtration system at the downstream end, and a roughly 25‑km iron‑concentrate pipeline connecting the Nanfen Concentrator to Benxi’s Type C stockyard. Nine Pulsar sonar flow meters have been installed along this pipeline.

Sierra Leone is located in West Africa and boasts favorable natural conditions and abundant mineral resources. Following the collapse of the colonial system after World War II, Sierra Leone gained independence from British colonial rule. Today, the country enjoys political stability and economic recovery, serving as a successful model of peaceful reconstruction—transforming from chaos to governance.

Nanjing Pulaisen Instrument Co., Ltd.’s sonar flowmeter overcomes the limitations of conventional measurement technologies such as electromagnetic, differential-pressure, and ultrasonic flowmeters. By leveraging advanced sonar‑based measurement principles and adopting a novel installation method—eliminating the need for pipe‑penetrating fittings—the sensor is mounted directly on the exterior of the pipe wall. This approach not only prevents production downtime and associated economic losses caused by instrument installation but also simplifies subsequent maintenance.

The Tonkili Iron Ore Project is one of the key cooperation initiatives between China and Sierra Leone. Located in the Tonkili mining area of the Northern Province of the Republic of Sierra Leone, it ranks among the world’s largest single‑site magnetite deposits. The Phase II beneficiation project entails constructing a concentrator with an annual capacity of 12 million tonnes, dedicated to the mining and processing of the transition‑zone iron ore.

The sonar flowmeter distributed by Nanjing Pulaisen Instrument Co., Ltd. overcomes the limitations of conventional measurement technologies such as electromagnetic, differential-pressure, and ultrasonic flowmeters. Leveraging advanced sonar‑based measurement principles, it also departs from traditional installation methods: no pipe‑cutting is required, and the transducer is mounted directly on the exterior of the pipe wall. This approach eliminates the economic losses associated with shutdowns caused by instrument installation, as well as subsequent maintenance challenges.

Mineral Processing–Hydraulic Transport Pipeline

Mineral Processing–Hydraulic Transport Pipeline

Wear, variations in ore properties, and high pressure all make flow measurement in hydraulic transport pipelines difficult and costly. Sonar flow meters are unaffected by these factors, enabling more cost-effective pipeline operation and leak detection.
