Oval Gear Positive Displacement Flow Meter


Oval gear flow meter is a kind of positive displacement flow meters(PD flow meters), applies to the measurement and control of fluid flow in custody pipeline. It has been widely used in petroleum,oil products,chemical fiber,food and weak corrosive mediums.

Product Features:

a. High accuracy,large flow range,good repeatability;

b. Simple structure,reliable operation;

c. Insensitive to liquid viscosity variation. Suitable to high viscosity medium measurement;

d. Flow state doesn’t affect the accuracy of measurement. Straight pipe is necessary for neither upstream nor downstream of flow meter.


 

Features                                                  

 

♦high accuracy:generally ±0.5%,higher ±0.2% is available or specail customize→used for precise

  flow measurement

♦ easy installation:no request on straight pipe,nothing to do with fluid flow status,no influence on

  accuracy in rotational flow→good for filed usage.

♦according to meter principle there will be less leakage for high viscosity from gear and      

  measurement space. the higher viscosity fluid medium is,the better measurement result flow

  meter get. →good for high viscosity fluid measurement.

♦direct-reading instrument,without external power supply.→read the cumulative flow rate directly
