Product details

XY - LZ metal tube rotameter under the main principle is to use a scale upward vertical cone tube of circular cross section of float is under the liquid force, gravity can float freely in the cone tube rises and falls, reached with the dial indicator flow through the magnetic coupling, this principle can be divided into glass rotor flowmeter and metal rotameter.XY - to make metal rotameter is the most commonly used in industry, adopts full metal structure, Modular design concept, the pressure loss is small, range than the big (10:1), easy installation and maintenance, can be widely used in complex, bad environment and various kinds of medium in the condition of the flow measurement and process control.
Metal tube rotor spinner flowmeter is one of the most commonly used in industry and laboratory flow meter, has the structure is simple, intuitive, small pressure loss, easy maintenance, etc.Rotor flowmeter is suitable for measuring straight through the pipe diameter D < 150 mm small flow, also can measure the rate of flow of corrosive medium.When using flow meter must be installed in vertical direction of the section, the fluid medium from bottom to top through the rotor flow meter.
Metal tube rotameter is widely used in chemical, petroleum, light industry, medicine, environmental protection, food and measurement test, scientific research departments, measurement of single phase of pulsating flow of fluid (liquid or gas).Glass rotor flowmeter has the strong corrosion performance, can detect acid (except hydrofluoric acid), alkali, oxidant and other corrosive gas or liquid flow, suitable for chemical, pharmaceutical, paper making, sewage treatment and other industries.
Second, the XY - LZ metal rotameter features:
1, suitable for small diameter and low flow velocity, high temperature, high pressure and strong corrosive medium flow measurement.
2, reliable operation, less maintenance, long service life.
3, for the straight pipe requirements is not high, wide flow than 10:1.
4, large LCD display, optional site, according to the instantaneous, the cumulative flow can bring backlit uniaxial sensitive indicator.
Three, XY - LZ metal tube rotameter parameters:

Four, notable matters of installation:
In order to make metal rotor spinner flowmeter work normally and can achieve a certain accuracy of measurement, the installation flow timing should pay attention to the following:
1, the metal tube rotor spinner flowmeter must be installed vertically on the no vibration of the pipeline.Fluid flows through the flowmeter from bottom to top, and the vertical degree is less than 2 °, horizontal when the horizontal Angle less than 2 °;
2, for the convenience of maintenance and replacement meter, measuring pipeline cleaning, piped in process of metal tube float flowmeter should install bypass pipe and the bypass valve;
3, metal tube rotor spinner at the entrance should be more than 5 times the pipe diameter length of straight pipe, the export shall be 250 mm straight pipe;
4, if the medium containing ferromagnetic material, magnetic filters should be installed;If the medium containing solid impurities, consideration should be given to the valve and straight pipe between the filter;
5, when used for gas measurement, should guarantee the pipeline pressure is not less than five times the pressure losses of flow meter to float a stable work;
6, in order to avoid deformation caused by pipe flowmeter, process pipeline flange must be flange with meter coaxial and parallel to each other, pipe supports in order to avoid pipeline vibration and reduce the axial load meter, control valve should be installed downstream of the flow meter in measurement system:
7, measuring gas, if direct discharge atmospheric gas flowmeter in exports, the valve should be installed in the export of instrument, otherwise it will be in the float produces pressure drop and cause data distortion.
8, the installation of PTFE lining instrument, the asymmetry of flange nut don't twist too tight, lest cause PTEF lining deformation;
9, with a liquid crystal display instrument, avoid direct sunlight displays, so as not to reduce the service life of the liquid crystal;Instrument with lithium batteries, avoid direct sunlight, high temperature (65 ℃) or higher environment so as to avoid reducing the capacity and life of lithium-ion batteries.
