LZD-50 Metal tube rotameter


LZD-50 Metal tube rotameter measures the fluid flow according to the throttling principle, In a vertical cone tube that expands from bottom to top, the gravity of the float of circular cross-section is borne by the hydrodynamic force, and the float can rise and fall freely in the cone tube. It moves up and down under the action of flow velocity and buoyancy. After balancing with the weight of the float, it is transmitted to the dial through magnetic coupling to indicate the flow.

Working principle

LZD-50 Metal tube rotameter measures, The flow of the fluid impacts the rotor and generates a force on it (this force changes with the flow); when the flow is large enough When the force is generated, the rotor is lifted and raised. At the same time, the measured fluid flows through the annular cross section between the rotor and the tapered tube wall. At this time, there are three forces acting on the rotor: the dynamic pressure of the fluid on the rotor, the buoyancy of the rotor in the fluid, and the gravity of the rotor itself. One of the rotameter is a tapered tube that gradually expands from bottom to top; the other is a rotor that is placed in a tapered tube and can move freely up and down along the center line of the tube . Rotor flowmeter When measuring the flow of fluid, the measured fluid flows in from the lower end of the conical tube.


1,Reliable work, low maintenance and long life

2,Suitable for small pipe diameters and low flow rates

3,With LCD liquid crystal display, it can display instantaneous and cumulative flow, and can also output pulse and output alarm

4,Has a wide flow range

Note:Any special design or question of LZD-50 Metal tube rotameter, kindly contact the manufacturer for more details.
