LZ-50 metal tube float flowmeter

Description :

　　LZ-50 metal tube float flowmeter

　　This product can achieve 4-20mA electric remote transmission signal, realizing functions such as remote display, recording, integration and control. The use of advanced microprocessor central chips and high-quality industrial components ensures the excellent performance of the flowmeter in various application scenarios.

　　1、 Working principle:

　　The measured medium flows through the measuring tube from bottom to top, generating a differential pressure at the upper and lower ends of the float to form an upward force. When the upward force on the float is due to the weight of the float immersed in the flowing fluid, the float rises, and the annular gap area increases accordingly. The fluid flow at the annular gap rapidly decreases, and the pressure at the upper and lower ends of the float decreases. The upward force acting on the float decreases until the upward force is balanced with the weight of the float immersed in the fluid, and the float stabilizes at a certain position. The height of the float position corresponds to the flow rate of the measured medium. The float is equipped with magnetic steel, and when the float moves up and down with the medium, the magnetic field changes with the movement of the float.

　　2、 Product features:

　　Suitable for flow measurement of small caliber and low velocity media.

　　Modular combination design, easy maintenance, and maintenance free normal use.

　　● Single axis sensitive indication, non-contact new magnetic coupling structure, more stable signal transmission.

　　Dual row, large screen LCD display for instantaneous and cumulative traffic, with backlight capability.

　　The intelligent model has power failure protection, data backup, and recovery functions.

　　All metal structure, earthquake resistant, pressure resistant, temperature resistant, anti-corrosion, long service life.

　　Low requirements for straight pipe sections.

　　Can be used in flammable and explosive hazardous environments.

　　Three power supply modes are available: DC24V, AC220V, and battery power supply.

　　3、 Installation:

　　The inlet of the 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

　　The metal tube float flowmeter should be equipped with a bypass to facilitate troubleshooting and ensure that it does not affect production during blowdown;

　　If the medium contains solid impurities, it should be considered to install a filter between the valve and the straight pipe section;

　　If the medium contains ferromagnetic substances, a magnetic filter should be installed;

　　When the temperature of the tested medium is higher than 220 ℃ or the fluid temperature is too low to cause crystallization, insulation protection measures should be taken, and a jacket type should be selected for cooling or insulation.
