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