Kofloc Model 2503F Flow Meter with Flow Controller

The constant flow valve Model 2203 that permits constant flow and the precision flow meter RK1400 are combined in this flow meter to permit high-precision measurement and control of a wide flow range, from very small flow to medium flow, when the pressure on the load side (outlet side) changes.

The natural environment is preserved through the balance of solids, liquids and gases that exist on the earth. However, human civilization has caused pollution that has greatly damaged our environment. The task of the present generation is to restore our environment to its natural healthy state. And this is also the greatest challenge for 21st century science and technology.

KOFLOC’s corporate motto is “A Scientific Approach for Fluids.” In other words, we create products that scientifically measure and control the balance of liquids and gases. We trust that through our work we are making a contribution to the regeneration of the environment and to the establishment of a prosperous society.

Features

  • This flow meter ensures constant flow under constant pressure on its inlet side even if the load pressure loss on the outlet side changes.
  • The measuring section of the flow meter is based on the highprecision float type flow meter RK1400.
  • The precision valve permits smooth and stable control of very small flow.
  • Constant pressure on the inlet side eliminates pressure errors of the float type flow meter, allowing a complete flow control system to be configured.
