Kofloc Model RK1650 Flowmeter

Description

An area flow meter has a float in a conical cylinde (tapered tube) with a larger end in the upper section and a smaller end in the lower section. The float moves up and down according to the intensity of the flow, and the position at which the float balances indicates the flow rate. Not only simple flow meters that merely measure the flow rate but also flow meters with a valve for flow control, flow meters with a load pressure fluctuation type flow controller, flow meters with a supply pressure fluctuation type flow controller, and flow meters with an alarm switch are available.

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.
