UF-E double rotator flow meter



 

UF-E double rotator flow meter



 

 



 

1. Overview:



 

UF-E is a newly developed
double-rotator positive displacement flow meter with unique design and delicate
workmanship of processing and assembling. Inside the meter, a pair of
spiral-shaped rotators is the only moving object which serves the function of
separating, calculating, transmitting and discharging the liquid being
calculated. In structure, this flow meter enjoys a rather rational design of an
additional positioning gear, allowing the two rotators to rotate without
interfering with each other. Besides, the meter has other merits like smooth
rotation, little noise, wear-resistance, high accuracy and excellent adaptation
to liquid of different thickness. Fine particles in the liquid can be allowed
to pass through the meter without jamming. Being nickel-plated, this meter is
resistant against wear and corrosion, suitable for replacing stainless steel
flow meters.



 

 



 

2.Features:

(1) Applicable to diluted oil, light oil, heavy oil, crude oil with large sand
and water      content, and the viscosity
range for liquid to be measured is wide.

(2) Liquid flow through the flowmeter is great, and the maximum flow is twice
that of   a common flowmeter of the same
drift diameter.

(3) Long service life, high accuracy and reliability.

(4) Minimal loss of inside pressure.

(5) The longest distance of wired transmission is 1,000m. Pulse signal output is N = 0.1L (1 pulse, 1N). It can also be directly
connected to a computer network.

(6) Intrinsically safe explosion-proof IaaCT4 (intrinsically safety type);
protection IP65.



 



3. Working principle:

    As shown below, the flowmeter
directly measures the volume of liquid flow with a special pair of rotary screw
rotors.

    The measurement of fluid flow by the
flowmeter is done in the cavity. A pair of screw rotors rotate under the liquid
pressure and each rotation will discharge eight times the shadow volume which
is the enclosed space formed between the rotor and flowmeter cavity (shaded
part in Figure). Therefore, according to this relationship, the flow
accumulation can be calculated as long as the number of rotor rotations is
measured, and the instantaneous flow can be measured according to the number of
rotations per second...
