Description :

　　Supply low-priced LWQ-25 gas turbine flowmeter

　　The main components of this product include rectifier grille, front diffuser, impeller, and rear diffuser. When the fluid passes through the pipeline, it impacts the impeller and generates a driving torque, causing the impeller to overcome friction torque and fluid resistance torque and rotate. Within a certain flow range, the rotational angular velocity of the impeller is proportional to the fluid flow velocity. Therefore, the rotational speed of the impeller is converted into an analog current through a magneto electric conversion device installed outside the casing, and then displayed as instantaneous flow rate value and cumulative flow rate value.

　　2、 Characteristics:

　　Wide measurement range, lower limit flow rate below 0.5m/s, low pressure loss, and strong impact resistance of the impeller.

　　It has high resistance to electromagnetic interference and vibration, and adopts fully sealed isolation protection for self-lubricating bearings, with 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. Correction formula

　　The accuracy is better than ± 0.02%.

　　The instrument coefficient can be set online through buttons and displayed on an 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.

　　Pressure compensation can be performed under stable pressure conditions of the measured gas.

　　3、 Installation:

　　1. The instrument installation adopts flange connection, threaded connection, and clamp 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 pipes should be installed outside the straight pipe sections at both ends of the sensor.

　　5. When installing sensors outdoors, please make sure to waterproof the amplifier plug.

　　6. The wiring of sensors and display instruments should be selected according to the power supply of the amplifier. Please refer to the relevant "user manual" for details.
