Micro-Flow Sensor: real-time flow monitoring

Reduce lost production time and maximise your line's efficiency

The micro-flow sensor can be used with needle metering valves to confi rm that material is being dispensed. It is designed for the detection of very small quantities (0.005 - 3.00 ml). This device is meant purely for material discharge monitoring purposes, not as a means of volumetric measurement.


The micro-flow sensor detects whether material has been dispensed or not, without contact with the material. An induced analogue measurement signal is amplified and forwarded to the electronic controller. The sensor is able to capture up to 120 metering cycles per minute. Should the electronic controller fail to send a signal as a result of no material flow, the master control unit will activate an alarm.
