Product Description

Product Description

Double -rotator flow meter

1.      Overview,
UF - E Double-Rotator Flow meter (Also called Bi-Rotor Flow meter, Dual rotor flow meter) is a new kind positive displacement item. Contained in measuring chamber is a pair of rotators having special spiral gear teeth, the design of which is responsible for successfully eliminating pulsation in flow stream. The special sands proof and self-lubricant designing can measure sands content and high water contains oil. This type flow meter has many advantages such as high-precision, high security, smooth running, low noise and long lifetime.
 

Flow meter Features:
1.      Apply to thin oil, light oil, heavy oil, viscous crude, crude oil with big water content, and wide viscosity of the liquid measuring.
2.      Big flow rate, the maximum flow rate is about 2 times of the normal displacement volume meter.
3.      Equipped with a super CPU count, through the form of conversion can be achieved a cumulative basis. Reset Calculation. Instantaneous flow. Alarm (when the low battery voltage), such as the LCD display.
4.      Have Mechanical counter electric counter two versions. Multi-output selectable: pulse, equivalent output, 4~20mA, RS485, Hart protocol etc.
5.      Isokinetic Rotary. And so on traffic. Such as torque.
As a result of the special gear spiral rotor,
(1)   such as rotary speed of sub-rotating,
(2)   Such as flow, no pulsation.
(3)   Rotary torque son must.
6.      Long service life, high accuracy and reliability.
7.      A pair of rotary speed rotary son, a very small pressure loss.
8.      Running smooth, no noise.
9.      The longest cable remote transmission distance of 1000 meters, the pulse signal output N = 0.1 L (a pulse to 1 N), can be directly connected with the computer.
10.  Explosion-proof IaIICT6 (intrinsically safe); Flame-proof dIIBT6; Protection IP65.

2.      Working principle
A positive displacement flow meter spiral rotor flowmeter includes a pair of smooth oval shaped rotors mounted to a pair of spaced apart rotatable shafts contained within a sealed housing. The rotatable shafts penetrate the measuring chamber and have a pair of toothed, oval shaped timing gears located in a separate gear cavity chamber which are responsible for synchronizing and maintaining the relative orientation of the smooth faced rotors with respect to one another. The fluid that is being metered forms seals between the rotating surfaces of the rotors, as well as between the rotors and the wall of rotor chamber, thus the inlet and outlet plenums are physically isolated and are consequently not in direct communication at any point during the rotation cycle of the rotors. Thus, each rotation of the rotors results in the transport of a precise and known volume of fluid from the inlet plenum to the outlet plenum. A magnetic sensing/counting system, which includes an magnetic actuator attached to one of the rotor shafts and a magnetic sensor mounted to the flow meter housing, monitors the rotation rate of the rotors and hence the flow rate of the fluid passing through the meter.
