Micro Flow Sensor

The MICRO-FLOW Sensor is a flow detectingdevice, used within a semi or fully automated metering process, to detect whether material has been dispensed.The MICRO-FLOW Sensor does not control the metering volume.

It is used particularly when handling unfilled grease with NLGI class 1 to 3, high viscosityoils or silicone-oils.The MICRO-FLOW Sensor can be adapted tothe DOPAG Micro and Mini metering valves aswell as to the 419 range of metering valves.

Features and benefits

  • Continuous detection of material flow
  • High process reliability
  • Simple refitting to existing metering systems
  • Compact sensor design
  • Dependable electronics
  • Simple operation
  • No mechanical adjustment required
  • Stainless steel wetted parts
  • Adaptable to all DOPAG needle nozzles

Function

The MICRO-FLOW Sensor detects whether material hasbeen dispensed or not, without contact with the material. An induced analogue measurement signal is amplified andforwarded to the electronic controller. The sensor is ableto capture up to 120 metering cycles per minute. Should the electronic controller fail to send a signal asa result of no material flow, the master control unit willactivate an alarm.
