Operating instructions for SIKA flow monitor type VH780 - Flow switch for direct mounting

The SIKA VH780 flow monitor is a universal metal flow monitor that has been specially developed for industrial applications. It is suitable for pipelines from DN 32 to DN 200 and is ideal for monitoring the flow of low-viscosity liquids. With a switching range of 15...1570 l/min (switch-on point) and 4.16...1513.33 l/min (switch-off point), the VH780 offers a precise and reliable solution for numerous industrial applications.

Areas of application:

The SIKA VH780 is optimized for monitoring the flow of liquids in pipelines and is used in many areas of industry, especially for low-viscosity media. Typical areas of application include

• Industrial plants
• Power plants
• Water treatment
• Oil and gas industry
• Energy supply
• Cooling circuits

Main features:

• Flow range (switch-on point): 15...1570 l/min
• Flow range (switch-off point): 4.16...1513.33 l/min
• Nominal diameter: DN 32 to DN 200
• Housing material: brass CW617N or stainless steel 1.4404
• Maximum operating pressure: 11 bar (standard), 30 bar (option)

Mode of operation:

The SIKA VH780 is a paddle flow switch that monitors the flow of liquids in pipes. The switch works on the basis of a microswitch that is activated by the movement of a paddle. When the flowing medium causes a change in pressure, the paddle is moved, which activates the microswitch and triggers a signal to monitor the flow.

• Paddle technology: By using paddle technology, the switch can be flexibly adapted to different nominal widths and switching points by selecting the right size of paddle.
• High switching currents: Thanks to the microswitch as a signal transmitter, the flow monitor can handle high switching currents.

Advantages:

• Easy installation: The VH780 is designed for direct installation in pipes and offers quick and easy integration into existing systems.
• Reliable monitoring: The switch is specially optimized for low-viscosity media such as water, oil or coolant and offers reliable performance.
• Versatility: Thanks to the ability to adjust the paddle, the flow monitor is suitable for a wide range of nominal sizes and flow rates.

Materials:

• Housing material: Brass CW617N or stainless steel 1.4404
• Paddles: Metal paddles for high durability in industrial applications

Extended functions and customization options:

• Switching point adjustment: By selecting the correct paddle size, the switching point can be precisely adjusted to the respective application.
• Robust design: The metal construction ensures a long service life and reliability even under demanding conditions.

Technical data:

• Flow range (ON): 15...1570 l/min
• Flow range (OFF): 4.16...1513.33 l/min
• Nominal diameter: DN 32 to DN 200
• Operating pressure:
  • Standard: 11 bar
  • Option: 30 bar
• Housing material: Brass CW617N or stainless steel 1.4404

Summary:

The SIKA VH780 flow monitor offers a reliable, precise and robust solution for monitoring liquid flows in pipelines, which can be used primarily with low-viscosity media such as water and oil. Thanks to its flexible customization options and compact design, the VH780 is ideal for industrial applications and ensures safe and efficient flow monitoring in various systems.
