Overview

The measuring component of the metal tube float flowmeter LZZ-50/RR1/M9/B1/Y consists of a conical measuring tube and a float. The float can freely move up and down in the conical measuring tube, changing the flow area in the pipeline. As the flow rate changes, the vertical position of the float in the measuring tube also changes accordingly. The position of the float is transmitted to the dial of the indicator through a magnetic transmission system through a steel tube, indicating the size of the flow value.

Installation precautions
In order to ensure the normal operation and measurement accuracy of the metal tube float flowmeter, the following points should be noted when installing the flowmeter:
·The metal tube float flowmeter must be installed vertically on a vibration free pipeline. The fluid flows through the flowmeter from bottom to top, and the verticality is better than 2 °. When installed horizontally, the horizontal angle is better than 2 °;
·For the convenience of maintenance, replacement of flow meters, and cleaning of measuring pipelines, metal tube float flow meters installed on process pipelines should be equipped with bypass pipelines and bypass valves;
·The inlet of the metal tube float flowmeter should have a straight pipe section of at least 5 times the diameter of the pipe, and the outlet should have a straight pipe section of 250mm;
·If the medium contains ferromagnetic substances, a magnetic filter should be installed; If the medium contains solid impurities, it should be considered to install a filter between the valve and the straight pipe section;
·When used for gas measurement, it should be ensured that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter to ensure stable operation of the float;
·In order to avoid deformation of the flow meter caused by the pipeline, the flange of the process pipeline must be coaxial and parallel to the flange of the flow meter. The pipeline support should be used to avoid pipeline vibration and reduce the axial load of the flow meter. The control valve in the measurement system should be installed downstream of the flow meter:
·When measuring gas, if the gas is directly discharged into the atmosphere at the outlet of the flowmeter, a valve should be installed at the outlet of the instrument, otherwise a pressure drop will occur at the float, causing data distortion.
·When installing instruments with PTFE lining, do not tighten the flange nuts asymmetrically at will to avoid deformation of the PTEF lining;
·Instruments with LCD displays should avoid direct sunlight on the display as much as possible to avoid reducing the lifespan of the LCD; Instruments powered by lithium batteries should avoid direct sunlight and high temperature environments (≥ 65 ℃) as much as possible to avoid reducing the capacity and lifespan of the lithium battery.
