Principle of Variable Flow Meter(Rotameter)
- Flow meter with valve
- KOFLOC is a general manufacturer of precision flow measuring and precision flow control instruments.
By combining these two technolo-gies, we manufacture float type flow meters with various valves.
For flow control, the flow must be measured almost all the time.
Assem-bling a valve and a fl ow meter separately and then combining them may have some merits in terms of specifi cations, but fl ow meters with a valve have more merits in terms of piping labor, mounting space, and possibility of general adjustment.
To meet such needs, KOFLOC manufactures flow meters with vari-ous types of valves, as represented by the flow meter with a needle valve.
Flow meters with a needle valve are subdivided into the simple type, precision type, large-capacity type, and bellows type, as well as models with a valve on the inlet side or on the outlet side.
In addition, flow meters with a variable primary pressure type flow controller, flow meters with a variable secondary pressure type flow controller, and flow meters with a sophisticated control valve are also available.
Most valves attached to these flow meters are basically identical to the fl ow control valves shown under different headings.
Reference pages for those valves are shown in the text of the catalog. Please refer to those pages for the detailed specifications, etc.
