1- LPG MECHANICAL FLOWMETER
LPG Mechanical Flowmeter
LC MA series flow meters are mechanical volumetric devices. They provide repetitive and precise volume measurements, regardless unstable working conditions resulting from changes of temperature and pressure of product handled. LC MA series flow meters are manufactured in wide range of sizes and in different material specifications. MA series meters are used at bottling plants, LPG terminals and in many other industrial applications.
LPG Mechanical Flowmeter
The original tri-rotor meter design consists of a housing in which three rotors turn and measure
fuel in synchronized relationship with no metal-to-metal contact.
The bladed displacement rotors alternately rotate through the half-cylinder bores of the meter element, while the single blocking rotor rotates within its bore to produce a continuous capillary seal between the unmetered product and the metered product.
Because the force exerted by the fluid flowing through the meter is at right angles to the faces of the
displacement rotors, and the rotor shafts are always in a horizontal plane, there is no axial thrust, thereby eliminating wear between the rotors and the bearing plates and ultimately providing a lifetime of measurment accuracy!
LPG Mechanical Refilling Cylinder Scale
The meter is a liquid measuring device. This volume meter operates with four pistons. Flow measurement is carried out by positive displacement of the four cylinder volumes by oscillating piston movement. LPG (liquid) passes through four cylinders that convert flow energy into piston movement.
These devices have played a pivotal role in gauging the flow of various liquids, notably liquid gas. The mechanical flow meter, in its essence, operates on the working principle of positive displacement. Here, a defined volume of liquid, be it liquid lpg is transported between sensors.
The mechanical types of liquid gas flow meters work by measuring the speed of water flowing through the pipe that causes a piston or turbine to rotate. The volumetric flow rate of the liquid gas is proportional to the rotational speed of the blades.

2- LPG MASS-FLOWMETER ( CORIOLIS )
LPG Mass-flowmeter (Coriolis)
The Coriolis flow meter operates as a precision instrument, employing the Coriolis effect to measure the flow of Liquefied Petroleum Gas (LPG) with exceptional accuracy. At its essence, the Coriolis effect is a physical phenomenon that manifests as a result of the Earth’s rotation.
Coriolis mass flow meters measure mass through inertia. A liquid or gas flows through a tube which is being vibrated by a small actuator. This artificially introduces a Coriolis acceleration into the flowing stream, which produces a measurable twisting force on the tube resulting in a phase shift.
