Guangzhou factory direct sales intelligent turbine flowmeter, pure water flowmeter, hot water flowmeter
- 1. Overview
- Turbine flowmeter
- It is manufactured by our factory using advanced foreign technology. One of the most ideal flow meters for liquid measurement. It has the characteristics of simple structure, high precision, easy installation, maintenance and use. This product is widely used in petroleum, chemical industry, metallurgy, water supply, papermaking, environmental protection, food and other fields to reliably measure the volume flow of liquids such as water, pure water, tap water, impurity-free sewage, diesel, gasoline and low-viscosity crude oil. Used in conjunction with display instruments with quantitative functions, it can be used for automatic quantitative control, upper and lower limit alarms, etc.
- 2. Product features:
-. The sensor is a carbide bearing thrust type, which not only ensures accuracy but also improves wear resistance.
-． The structure is simple, firm and easy to disassemble and assemble.
-． The measurement range is wide and the lower flow rate is low.
-． Small pressure loss, good repeatability and high accuracy.
-． It has high anti-electromagnetic interference and anti-vibration capabilities.
- 3. Working principle:
- The fluid flows through the sensor housing. Since the blades of the impeller have a certain angle with the flow direction, the impulse of the fluid causes the blades to have a rotational moment. After overcoming the friction torque and fluid resistance, the blades Rotation, the speed is stable after the torque is balanced. Under certain conditions, the speed is proportional to the flow rate. Since the blade has magnetic permeability, it is in the magnetic field of the signal detector (composed of permanent magnet steel and coils), and the rotating blade cuts the magnetic lines of force. , periodically changes the magnetic flux of the coil, thereby inducing an electric pulse signal at both ends of the coil. This signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to the display remotely. The instrument displays the instantaneous flow rate and cumulative amount of fluid. Within a certain flow range, the pulse frequency
- is proportional to the instantaneous flow rate
- of the fluid flowing through the sensor. The flow equation is:
