Description

LWGY series turbine flow sensor (hereinafter referred to as the sensor) is based on the principle of torque balance and belongs to the velocity type flow meter. The sensor has a simple structure, lightweight, high accuracy, good reproducibility, responsive, easy to install and maintain the use of the characteristics, widely used in petroleum, chemical, metallurgical, water supply, paper and other industries, is the ideal instrument for flow measurement and energy saving.

The sensor is used in conjunction with the display instrument, and is suitable for measuring the liquid in closed pipes with stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum Al2O3, hard alloy does not corrode, and there are no fibers, particles and other impurities. If matched with the display instrument with special functions, it can also carry out quantitative control, over quantity alarm, etc. The explosion-proof type of this product can be used in explosive environments.

The sensor is suitable for media with viscosity less than 5×10-6m2/s at working temperature. For liquids with viscosity greater than 5×10-6m2/s, the sensor should be calibrated with real liquid and then used.

If the user needs to use special forms of sensors, can negotiate the order, need explosion-proof sensors, in the order to specify.

Second, LWGY basic turbine flow sensor
2.1 Structural features and working principle
(1) Structural characteristics
The sensor is a carbide bearing thrust type, which not only ensures accuracy and improved wear resistance, but also has a simple and solid structure as well as easy disassembly and installation.
(2) Working principle
Fluid flow through the sensor shell, due to the impeller blade and the flow direction has a certain angle, the impulse of the fluid so that the blade has a rotating torque, after overcoming the friction torque and fluid resistance blade rotation, in the torque balance speed stability, in certain conditions, speed and flow speed is proportional, because the blade has magnetic conductivity, it is in the signal detector (by permanent magnet and coil composition) of the magnetic field, the rotating blade cutting The magnetic force line, periodically changing the magnetic flux of the coil, so that both ends of the coil induction out of the electrical pulse signal, this signal through the amplifier amplification and shaping, forming a certain amplitude of continuous rectangular pulse wave, can be transmitted to the display meter, showing the instantaneous flow or total amount of fluid. In a certain flow range, the pulse frequency f is proportional to the instantaneous flow rate Q of the fluid flowing through the sensor, and the flow equation is

f - pulse frequency [Hz]
k - instrumentation factor of the sensor [1/m3], given by the calibration sheet. If [1/L] is used as the unit
Q - instantaneous flow rate of the fluid (in working condition) [m3/h]
3600 - Conversion factor
The instrumentation coefficient of each sensor is filled in the calibration certificate by the manufacturer, and the k-value is set into the matching display instrument, which can display the instantaneous flow and cumulative total.
