Sight Flow Indicators

A sight flow indicator is a mechanical device installed in a pipeline to provide direct visual confirmation of liquid or gas movement. HK Calibrations provides these essential tools to Australian industries to help operators quickly verify flow presence, direction, and fluid condition without relying on complex electronics.

Our range includes various internal designs such as rotors, flappers, and drip tubes to suit different flow rates and fluid types. HK Calibrations supplies Australian technicians with versatile Series SFI indicators that make it easy to monitor everything from low-volume drips to high-velocity process streams.

While both allow visual inspection, sight windows like the Series 550 are often used on tanks and vessels to show levels or contents through fused glass. HK Calibrations offers these robust viewing ports to Australian facilities that require reliable, continuous monitoring of fluid clarity and color in high-pressure environments.

Yes, models like the Series SF combine a visual sight tube with a 4-20 mA transmitter output for remote monitoring and alarms. HK Calibrations delivers these smart solutions to Australian industrial sites that need both manual operator observation and real-time data for automated process control.

Our indicators are constructed from corrosion-resistant materials such as 316 stainless steel, brass, and bronze to handle harsh industrial media. HK Calibrations ensures that Australian engineers have access to safety-tested devices built to withstand high temperatures and pressure fluctuations in demanding workflows.

We offer a comprehensive selection of high-performance indicators backed by nationwide Australian support and professional calibration expertise. HK Calibrations helps you maintain operational confidence by providing accurate, traceable measurement tools that comply with strict Australian quality and safety standards.
