LSZ Series Double-Rotator Flowmeter

General
LSZ- Double-Rotator Flowmeter is the latest & international super-class volumetric-type flowmeter. It is a
type of precise instrument measuring and controlling liquid flow in the pipeline, featuring high measurement
precision, smooth running, free of pulsation, low noise, long service life and excellent adaptability to
viscosity etc.. Therefore, the product has been widely used in various fields such as petroleum, chemical,
metallurgy, EPT power, shipping, traffic, dock, mine, thermal power, and foodstuff industries etc.. It is
especially suitable for commercial trade measurement for crude oil, high condensation oil, crude oil with
high water content, petroleum products, foodstuff and chemical solutions as well as measuring
management and control of engineering automation. The codes and characters displayed on the flowmeter
can be directly read locally. The photo- EPT pulse converter equipped can output EPT pulse(current)
signals to the displaying instrument and computer for handling. Thus, the flow in the pipeline can be
remotely controlled.
                                                          
Principle
The measuring chamber of the double-rotator flowmeter consists of interior casing, a pair of helix rotators
and top & bottom cover plates. These formed a cavity with known volume which can be used as the
measuring unit for the flowmeter. The rotator of the flowmeter rotates under the tiny pressure difference
between the inlet and outlet and continually sends the liquid at inlet to the outlet after cavity
measurement(See Fig.2). The rotator transmits the rotating numbers to the counter by means of sealed
coupling and driving system so that the total volume of the liquid passing the flowmeter can be directly
displayed.

  1. Inner measuring chamber
  2. Chamber cases
  3. Rotors

LSZ is a positive displacement meter utilized in the most demanding applications requiring accuracy, long life and ruggedness. It features two precisely machined rotating members known as helical rotors which rotate and mesh within the meter’s interior housing in order to form a measuring chamber of known volume which may be used to accurately determine volumetric flow rate as a function of the rotors’ velocity. As liquid enters the intake of the measurement element, two finely timed rotors divide the liquid into precise segments of known volume and return those segments to the flowing stream. During this transition, the rotation of the two rotors is directly proportional to volumetric throughput. Volume indication is determined by mechanical output gearing leading to electronic or mechanical  registration devices
