Product Introduction

HY-LWGY turbine flowmeterIt is one of the flow meters for measuring liquids. It has the characteristics of simple structure, high measurement accuracy, long service life, simple operation, and easy maintenance. This product is widely used in metallurgy, chemical industry, petroleum, urban construction, environmental protection, food and other fields to measure the flow rate of liquids such as water, tap water, diesel, gasoline and light finished oil with high precision.

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.

Product Features

1. Low pressure loss and impeller with 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. The intelligent flow display with non-linear accuracy compensation function has a correction formula accuracy better than 0.02%.

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

5. Using EEPROM for power down protection of cumulative flow and instrument coefficient, with protection for more than 10 years.
