The DG08 mechanical flow indicator is used for visual verification of the flow of liquids or gases. The liquid or gas being monitored lifts the PTFE ball from its valve seat. As the flow increases, the ball in the domed sight glass becomes increasingly visible. These devices are made of high-quality materials, allowing them to be used with a great variety of liquids or gases.

DG08 mechanical flow indicators are used to monitor the flow of liquid or gaseous media. These devices are especially suited for use in industrial systems and for process monitoring as well as for basic monitoring of compressors, ventilators, fans and many other types of similar equipment.

The DG06 flow indicator allows visual and quantitative monitoring of liquid flows. The device has two large glass panes – one on each side – and each with a scale attached. A stainless steel flap mounted in the flow chamber is lifted when there is flow and the current flow rate is displayed on the scale. The flap is mounted on a stainless steel shaft; it is raised by flow and lowered by gravity. The DG06 can be installed both horizontally and vertically (with flow from bottom to top) and deployed in a wide variety of applications – not least because it is not adversely affected by high temperatures.

DG10 sight glasses are used to visually monitor the flow of liquids in pipe systems.

Depending on the type of liquid and flow volume, these devices are used with a fully clear bore or with a flap or rotor (for transparent liquids).

DG10 sight glasses permit reliable monitoring of the function and performance of single devices or entire systems.

Model series DG04 sight glasses are distinguished by their rugged construction and wide range of applications. They feature 0.94", 1.18", or 1.97" / 24, 30, or 50 mm long transparent cylinders made of acrylic, soda-lime, or borosilicate glass with very high wall thickness. These cylinders are intended to be clamped between two existing flanges. Their dimensions match those of the sealing face on the raised area of the flange. This sizing makes support from a separate metal housing unnecessary. In addition, this design allows the flow to be viewed and monitored from any direction. The flange bolts also offer additional protection against mechanical damage.The borosilicate glass version can be installed in devices used with very caustic/corrosive liquids. They are insensitive to contamination because the inner surface is constantly being rinsed by the flowing liquid. In particular, the larger nominal sizes are very cost effective solutions since they only require the transparent cylinder and no metal housing with flanges.

The DG02 mechanical flow indicator is used for visual verification of liquid flow. The rotational speed of the rotor is proportional to the liquid flow rate. The domed sight glass allows the rotor to be easily seen at any time. These devices are made of high-quality materials, allowing them to be used with a great variety of liquids.

DG02 mechanical flow indicators are used to monitor the flow of liquids of low to medium viscosity in pipe systems.
