Positive displacement oval gear flow meter

    Oval gear flowmeter displacement meter, also known as fixed displacement meter, elliptical gear at the beginning of each rotation 4 times a week can be output volume of the cavity, therefore, the elliptical gear revolution is proportional to the fluid flow.

1. Oval gear flow meter common faults and treatment methods

   Fault	Reason	Treatment methods
   elliptic gear does not rotate	1.debris in the pipe	1.Clean the flowmeter and pipe.
   	2.filter is damaged, the sundries are in the table, and the gear is stuck.;	2.Repair filters;
   	3.Because of the excessive flow, bearing wear, the gear collides with the bore, causing the gear to jam.	3.Replace the bearing to ensure the clearance is flexible.
   Elliptical gear rotation         Pointer does not move	4.Rotating fasteners sliding, damaged or not flexible;	4.Tighten the fastener to remove the inflexible;
   	5.Magnetic coupling sliding;	5.Check whether the magnetic coupling is flexible and strong;
   	6.The word wheel part is stuck.	6.Troubleshoot the word wheel parts.
   Flow meter has a            large positive error	7.The flow has a large pulsation or contains gas;	7.Reduce flow pulsation or increase gas separator;
   	8.The actual liquid viscosity is greater than the test liquid viscosity;	8.Select the test liquid to check the flow meter or viscosity correction with the actual liquid viscosity;
   	9.Small inlet valve, medium not full of measurement room measurement.	9.Use flow meter outlet valve to control medium flow.

The flowmeter are normally possible fault can be found in the above account causes and corresponding processing methods, if a fault does not find a reason, you can contact us, providing professional solutions.
