SIGHT FLOW INDICATORS

The sight flow indicators serve multiple industry applications in fluid monitoring. These devices offer valuable insights into the fluid movements within piping systems and ensure the assurance of operational efficiency. They come with two distinct types, the view-through flow indicators and the 360° or full view flow indicators. To assist with assisting flow direction, these indicators are equipped with diverse indications like rotary, flapper, flutter, ball, or drip.

CMC Technologies provides the liquid monitoring tools that are required for ensuring smooth and visible fluid flow monitoring.
