The electronic flow monitor is suitable for simple control and monitoring of cooling lubricant systems and coolant circuits, control of filter units or as dry-running protection of pumps. It measures the flow and temperature of aqueous fluids according to the wear-free calorimetric principle. Thanks to the Teach function, the zero point and the maximum flow can be adjusted easily at the measurement point. A switching output can also be used as a temperature switch.
