Liquid LWGY turbine flowmeter LWGY-80 flange turbine flowmeter

Description :

　　This product is widely used in the measurement and control systems of petroleum, chemical, metallurgical, scientific research and other fields. It can display the total flow, instantaneous flow, and flow saturation percentage.

　　1、 Technical parameters:

　　Nominal diameter: Pipeline type: DN4~DN200

　　Insertion type: DN100~DN2000

　　Accuracy level: Pipeline type: ± 0.5 level, ± 1.0 level

　　Insertion type: ± 1.5 level, ± 2.5 level

　　Environmental temperature: -20 ℃~50 ℃

　　Medium temperature: Measuring liquid: -20 ℃~120 ℃

　　Atmospheric pressure: 86KPa~106KPa

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

　　Explosion proof grade: ExdIIBT4

　　Liquid: The upstream straight pipe section should be ≥ 20DN, and the downstream straight pipe section should be ≥ 5DN

　　2、 Characteristics:

　　1. The pressure loss is small, and the impeller has anti-corrosion function.

　　2. Has high resistance to electromagnetic interference and vibration, reliable performance, and long working life.

　　3. Adopting advanced ultra-low power single-chip microcomputer technology, the whole machine has strong functions, low power consumption, and superior performance. Intelligent flow display with non-linear accuracy compensation function. The accuracy of the correction formula is better than 0.02%.

　　4. The instrument coefficient can be set online through buttons and displayed on an LCD screen, which is intuitive, clear, and highly reliable.

　　5. The intelligent turbine flowmeter adopts EEPROM for power down protection of accumulated flow and instrument coefficient.

　　3、 Installation and maintenance:

　　1. Installation adopts flange connection, threaded connection and clamping type;

　　2. The direction of liquid flow during installation should be consistent with the direction indicated by the arrow on the sensor housing, and the upstream straight pipe section should be ≥ 6DS, and the downstream straight pipe section should be ≥ 5DS (DS is the measured inner diameter of the tested pipeline);

　　3. Sensors should be kept away from external magnetic fields. If unavoidable, necessary measures should be taken;

　　4. In order to avoid affecting the normal transportation of liquids during maintenance, bypass pipelines should be installed outside the straight pipe sections at both ends of the sensor;

　　5. When installing sensors outdoors, please ensure that the amplifier plug is waterproofed;

　　6. The wiring between sensors and display instruments should be selected based on the power supply of the amplifier.
