General Characteristics
The CV flow indicators are designed for visual monitoring of liquid flow in hydraulic and lubricating systems. They feature a colored propeller for enhanced visibility with dark liquids and are constructed with a natural tempered glass sight tube. Key features include rugged construction, bidirectional operation, and easy installation.

Technical Data
The flow indicators are available in various sizes, with specifications such as:

• Minimum and maximum flow rates (Q min. and Q max.)
• Pressure drop (∆P max) and maximum pressure (P max)
• Maximum temperature (T max)
• Weight and dimensions for each size

For example, the 1/4” size has a Q max of 6 l/min and a weight of 0.11 kg.

Materials
The materials used in construction include:

• Body and connections: Polysulfon, Brass (nickel plated), or Anodized Aluminum
• Propeller: Red Polypropylene (PP)
• Axle: Polypropylene (PP)
• Sight tube: Tempered glass
• Seal: NBR

Mounting
The mounting position is flexible, but care must be taken to ensure pipes are aligned with the propeller indicator axle when connecting directly with rigid pipes.

Nomenclature
The nomenclature for the flow indicators includes the type, process connection size and thread, and materials of the body and connections, as exemplified by CV 025G PSO.
