Reliable container flow indicator for visual monitoring!

Within closed pipework or pressure tanks, it can be helpful to install sight flow indicators to visually monitor and control the media. The sight flow indicator allows you to monitor the direction of flow, and to check for foreign particles, which could damage the machine or the application. That makes the sight flow indicator perfect for visual monitoring, for example in a round, oval or rectangular shape. The construction resembles DIN 28120 or DIN 128121, which allows for easy welding. NieRuf is your partner for high-quality sight flow indicators.
