Dual power LWGY turbine flowmeter LWGY-40 liquid turbine flowmeter

Description :

　　This product is easy to install, with sensors that have high accuracy, good repeatability, long lifespan, and simple operation. It can be widely used in industries such as petroleum, chemical, metallurgy, and papermaking to measure the instantaneous flow rate and total volume of liquids.

　　1、 Characteristics

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

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

　　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%.

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

　　Using EEPROM for power down protection of accumulated flow and instrument coefficient. The protection period is greater than 10 years.

　　Explosion proof grade: ExdIIBT4

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

　　3. Installation

　　1. The instrument 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.
