This new double window Flow Indicator range from Flow-Mon is most useful where visual inspection of the pipeline content is needed as a plant safety or product quality measure. The sizeable windows allow an excellent view of the conditions in the line.
The plain Spout design affords visual inspection only while the hinged internal Flap with its graduated scale allows a check on flow rate changes and for instance, affords repeatability of valve positioning. The Flap or Spout can be used in transparent or slightly opaque solutions and gas services. Both units will operate in horizontal or vertical orientation (up only for Flap style).
The Spinner Double Window Sight Glass is suitable for monitoring in a vertical or horizontal position. This style like the Flap and Spout is available with threaded (BSP or NPT) as well as Flanged connections. The 8 bladed PTFE spinner and Stainless Steel internals give excellent corrosion resistance.
With the flap and easy to read sacale the Flapper sight flow indicator is used to check the flow rate of a liquid in a pipeline. It can be used in vertical or horizantal lines and ideal as a plant safety device where you need to maintain a constant flow, for example in lubricating or cooling systems.Flapper sight flow indicator is used to check the flow rate of a liquid in a pipeline.
