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, electric power, shipping, traffic, dock, mine, thermal power, and foodstuff industries etc.. It isespecially 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-electric pulse converter equipped can output electric 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.
Picture 2: The Principle of LSZ- Flowmeter
                                               
                                                         
LSZ- Double-Rotator Flowmeter 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
