Variable area Control signal output Glass tube rotameter fuel oil flow meter rotameter air
MT-DK800-6,  SS304, flow range 0.5-5L/h,39USD/pc, 5-7 Days delivery, 0.5KG/pc


  Variable  area  flow meter  is a kind  of  on-the-spot instrument for  use  of  measuring  and  indicating  instantaneous   flow  rate  of  liquid  or  gas  in  closed  pipeline, being  widely  used  in  chemical  plant, petroleum  industry, pharmaceutical  factory,  food processing  and  scientific  research.


Flow meters DK800 are manufactured by special technique and equipment of KROHNE  company in German. This miniature model has a fine adjusting valve to facilitate precise setting of the flow rate.A specially designed fitting permit easy cone replacement without having to remove the flow meter from the pipe run. It can be connected with hose or metal pipe.Float material is agate or  OCr18Ni12Mo2Tiss.  DK800-2 is applied to measuring and controlling extremely small flow  rate.

What are Flowmeters ?
A flowmeter is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas.

Selecting a Flow Meter
The basis of good flowmeter selection is a clear understanding of the requirements of the particular application. Therefore, time should be invested in fully evaluating the nature of the process fluid and of the overall installation.

Here are some key questions which need to answered before selecting a flowmeter:

  • What is the fluid being measured by the flowmeter or flowmeters (air,water,etc)?
  • Do you require rate measurement and/or totalization from the flow meter?
  • If the liquid is not water, what viscosity is the liquid?
  • Is the fluid clean?
  • Do you require a local display on the flow meter or do you need an electronic signal output?
  • What is the minimum and maximum flowrate for the flow meter?
  • What is the minimum and maximum process pressure?
  • What is the minimum and maximum process temperature?
  • Is the fluid chemically compatible with the flowmeter wetted parts?
  • If this is a process application, what is the size of the pipe?
