Overview

The float of the metal tube float flowmeter moves upwards with the change of flow rate in the measuring tube, and at a certain position, the buoyancy and gravity of the float reach equilibrium. At this time, the circulation gap area between the float and the orifice plate (or cone tube) remains constant. The annular gap area is directly proportional to the rising height of the float, that is, the position where the float rises in the measuring tube represents the size of the flow rate. The change in the position of the float is transmitted by the internal magnet to the external indicator, so that the indicator correctly indicates the current flow rate value.

Product Details

One product overview

The ZY-LZ metal tube float flowmeter adopts the variable area measurement principle and is used to continuously measure the mentioned flow rate of liquids and gases in closed pipelines. There are on-site display type and intelligent remote transmission type that support multiple output protocols, providing users with a very wide selection space; In addition, the instrument adopts advanced 16 bit microprocessors and high-quality industrial components, ensuring the good performance of the flowmeter in various application scenarios.

The ZY-LZ metal tube float flowmeter adopts the principle of variable area measurement and is used for continuous measurement of the mentioned flow rate of liquids and gases in closed pipelines. It can be used to detect the flow rate of liquids, gases, and vapors, and is particularly suitable for measuring the flow rate of low flow and small flow media.
