Stainless steel LWGY turbine flowmeter LWGY-50 flange turbine flowmeter

Description :

　　This product has obvious advantages such as compact structure, intuitive and clear reading, high reliability, no external power interference, lightning resistance, and low cost.

　　1、 Characteristics:

　　1. High precision, generally ± 0.25% R - ± 0.5% RH% for liquids, and up to ± 0.15% RH% for high-precision types.

　　2. Good repeatability, short-term repeatability can reach 0.05% -0.2%.

　　3. High frequency signals (3-4kHz) can be obtained with strong signal resolution.

　　4. Wide range, with a medium to large caliber of up to 40:1-10:1 and a small caliber of 6:1 or 5:1.

　　5. Compact and lightweight structure, easy installation and maintenance, and high circulation capacity.

　　2、 Technical parameters:

　　Measurement caliber: Pipeline type: DN0.5~DN600;

　　Accuracy level: ± 0.2%, ± 0.5%, ± 1.0%;

　　Environmental temperature: -20 ℃~+50 ℃;

　　Medium temperature: Measurement liquid: -20 ℃~+120 ℃;

　　Nominal pressure: 1.6 Mpa, 2.5 Mpa, 6.4 Mpa, 25 Mpa;

　　Explosion proof grade: ExdIIBT4;

　　Connection methods: threaded connection, clamp connection, flange connection, plug-in connection, etc;

　　Output function: Pulse output, 4-20mA two-wire current output, with RS485 communication interface.

　　3、 Installation:

　　1. Insufficient length of upstream and downstream straight pipe sections;

　　2. The deviation between the inner diameter of the instrument measuring tube and the inner diameter of the piping is large;

　　3. Install non concentric seals protruding into the pipe;

　　4. Reverse installation of instrument flow direction;

　　5. The detection component is covered by impurities;

　　6. Reduced detection sensitivity, small flow leakage meter;

　　7. Pipeline leakage (such as underground pipelines where small leaks are not detected), valve leakage, and bypass valve leakage result in a relatively small cumulative flow (total amount);

　　8. The presence of two-phase flow and pulsating flow affects accurate measurement.

　　4、 Working principle:

　　The turbine inside the sensor rotates under the action of fluid, causing a change in the magnetic field of the signal detector. Therefore, an alternating voltage is induced in the coil of the signal detector, which is amplified, filtered, and shaped by an amplifier to output a square wave signal. The frequency of this signal voltage is directly proportional to the speed of the impeller, that is, directly proportional to the flow rate (velocity) of the fluid.
