JSF flow monitor for 1…8″

This flow monitor was specially developed to monitor the flow of liquid media. The monitor is typically used in mechanical and apparatus engineering, for monitoring oil, cooling and lubrication circuits or as a low-water safety device in sprinkler systems, heating systems, chillers and heat pumps. They are installed vertically in a horizontal pipe. The calming section must be at least 5 times the pipe diameter upstream and downstream of the paddle. The maximum flow can be considerably higher than the maximum setting value of the monitor. Not tested for drinking water.
