Circulation lubrication

Modular construction oil circulation lubrication meters for paper machines

  • RealFlow digital oil flow meter
  • FO-OilFlow variable area oil flow meter


FO-OilFlow circulation lubrication meters unique self-cleaning technology ensures that the flow tube indicator remains clean. The measuring technique is spring loaded and based on pressure differences. Because of the spring load, flow rate is constant and accurate.

Flow levels are adjusted directly according to the flow tube scale, removing the need for a conversion scale. In normal operation, floats are always on the same level regardless the flow rate. This makes it easier to monitor flow meters visually, i.e. just a glance is enough to check the operation of the entire group. Optional lower limit ensures that circulation lubrication reaches every oiling point.

FO-OilFlow advantages:

  • Direct flow capacity display l/min
  • Built in modular form (1 – 12 pcs/base plate)
  • Cleans the display automatically
  • Spring loaded to ensure stable operation
  • Quick and easy to adjust


The RealFlow is a digital oil flow meter which is specficially designed for measuring and monitoring the volumes of oil flow circulation in a paper machine. The RealFlow unit can also control the volume of lubrication oil flow, as well as generate accurate real-time measurement data for the SCADA system.

Flow rates are formed by measuring pulses from a pair of oval gears inside the RealFlow meter, using an inductive sensor. The flow meters’ operating condition can be observed at a glance by the flashing of the inductive sensor’s leds.

States of flow rate, set point and alarm limits (Hi, Lo, Lolo) are available in real-time from every measurement point. Alarms are of relay-type binary alarms. The SCADA software allows the reading and writing of these parameters from every assembled measurement station. Data transmission to and from measurement stations can be implemented by using the Modbus RTU- or TCP-protocols.
