LS series rotary piston flowmeter

The LS series flowmeter is the first newly developed rotary piston flowmeter in China. With advanced domestic level, due to its low flow lower limit, wide range, high accuracy, simple structure, reliable operation, and lower price than volumetric flow meters of the same specifications, it can be directly installed in trains, tractor generator sets, inland or offshore ships to measure the fuel consumption of various power machines, as well as the loading and unloading measurement of various heavy liquids and pipeline liquid measurement. It is the best instrument for liquid material assessment and management, which is conducive to the in-depth development of energy-saving work. It is currently an ideal fuel consumption meter that can be applied to a wide range of transportation vehicles, and is highly welcomed by energy measurement departments, scientific research departments, transportation departments, vehicle and vessel manufacturers, and various liquid manufacturers.

Working principle of LS series rotary piston flowmeter

A flowmeter consists of a housing, piston mechanism, and other components. The counting mechanism is completely isolated from the oil and relies on magnetic transmission. When the instrument is connected to the pipeline and fuel flows through, the pressure difference on both sides of the inlet and outlet will push the piston to rotate. At this time, the magnetic coupling connected to the piston also rotates. Since the number of revolutions of the piston is proportional to the amount of oil flowing through the instrument, the number of revolutions of the piston counted by the counting mechanism is a multiple of the amount of oil flowing through the instrument.
