Flowmeters Flow Measurement Fast, Versatile and User–Friendly
Flowmeters and sensors are a typical component of industrial production processes. User friendly, versatile and cost–effective units are in high demand. Sensor specialist Jumo tries to meet all these requirements with its new Pinos L01, an electronic flow sensor with especially quick reaction times.
The device is intended for use in water and watery mediums, for example in cooling circuits, compressors, pumps and heat exchangers. However, the unit can also be used to protect pumps against dry running and in lubricant circuits. The device reacts quickly, is easy to install (not dependent on the orientation) and simple to operate. Configuration is done using an USB interface. The new flow sensor works according to the calorimetric measurement principle: The sensor is submerged in the flowing medium which washes around it. A heating element and a temperature sensor make up the sensor – on the one hand, the heating element is continuously supplied with a small amount of electrical energy while at the same time this temperature increase in the sensor is discharged through the flowing liquid. The temperature conditions that arise are measured by the temperature sensor. In simple terms, the faster the liquid flows, the more the heating element is cooled. Consequently, the flow speed of the liquid can be determined using a simple temperature measurement without moving parts.
