LZ -Variable-Area fuel Oil Flow Meter

Megnetism Fiter

If there are some ferromagnetism granule in the medium, a magnetism filiter must be installed in the entrance of the flowmeter .There are some magnetism sticks which are ranked in helical in the magnetism filter, it can cutt down pressure loss maxinunly.Every magnetism stick is coverer with PTPE, prevent from corresiom by medium.

I type:Flange conneetion, height :100mm

IItype :Inpacted installation, heigh:50mm

Antivibrator(gas)

If the flow (pressure)in the entrance of the flow meter is unsteaediness.in order to ensure that the flowmeter can work steadily and credily for long time when we measure clean gas we can install an antivibrator with high tech manufacture .On the measure component.

It is unfit for using an antivibrator if there are some tiny granule or dust in the gas .Under this civcumstance , it is request the pressure in the entrance is bigger than 5times of flowmeters pressure loss so we can ensure that flowmeter can work nomally. For diameter D15, we can level off the flow by pressure adjuster.
