LWGY smart turbine flowmeter, intelligent turbine flow meter with a battery-powered DC power supply type, may be suitable for measuring multiple pressure levels, beautiful appearance, easy installation, low maintenance, free debugging, measurement precision wide range of applications. One, LWGY smart turbine flowmeter Product Overview LWGY Series Intelligent turbine flowmeter flow meter is learned at home and abroad advanced technology optimized design, has a simple structure, lightweight, high precision, reproducibility is good, responsive, and easy installation and maintenance. Features of the new generation of turbine flowmeters are widely used to measure the closed pipe and stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum Al2O3, carbide corrode, and no fibers, particles and other impurities, the kinematic viscosity at operating temperature is less than 5 × 10- 6m2 / s of the liquid, for kinematic viscosity greater than 5 × 10-6m2 / s of the liquid, the flow meter can be calibrated after the solid solution used. If the display instrument with special features, can also be quantitative control, excessive alarm, etc., is an ideal flow metering and energy meter. Instrument inexpensive, high integration, small size, especially for the secondary display device, PLC, DCS and other control systems with the use of a computer. Second, the principle structure ?? LWGY LWGY turbine flowmeter turbine flowmeter by the turbine, bearings, preamplifier, display instrument components. The impact of the measured fluid turbine blades, the turbine rotation speed of the turbine varies with changes in flow, that flow, the speed of the turbine is also large, and then the magnetic-electric conversion device converts the rotational speed of the turbine corresponding frequency electrical pulses through After the pre-amplifier, into the display instruments are counted and displayed, you can find the instantaneous flow rate and cumulative flow based on the number of pulses and the cumulative number of pulses per unit time. The turbine works when the transmitter is in fluid flow along the axial direction of the pipe, and the impact of the turbine blades when the flow rate there qv, velocity V and the fluid density ρ is proportional to the product of the force on the blade, drive a turbine to rotate. In the rotation of the turbine, while the blade is periodically cut magnetic lines generated by the electromagnet, the coil of the magnetic flux change. According to the principle of electromagnetic induction, a coil will induce a pulsating potential signal measured fluid flow rate is proportional to the frequency of this pulsating signal. Turbine output pulse signal transmitter, premenstrual placed after the amplifier, into the display instruments, flow measurement can be achieved. Three, LWGY turbine flowmeter product features a high accuracy, generally up to ± 1% RF, ± 0.5% RF, high-precision up to ± 0.2% RF 2, repeatability, short-term repeatability of up to 0.05% ~ 0.2%, it is due to good reproducibility, such as frequent calibration or online high accuracy calibration available in trade settlement is the preferred flow meter 3, the output pulse frequency signal, suitable for the measurement of total and with computer connection, no zero drift, anti-jamming 4, get a high frequency signal (3-4kHz), 5 signal resolution and strong, wide flow range, medium and large caliber up to 1:20, the small diameter of 1: 106, compact, lightweight, easy installation and maintenance, flow capacity 7, for high pressure measurement, the meter body does not have to cut, easy instrument made of high-pressure type 8, special type of sensor types, can be designed according to the special needs of each Class-specific sensors, such as low temperature, bi-directional, underground type, sand and other special-9, can be made to insert type, suitable for large diameter measurement, pressure loss, low price, do not remove the drying, easy installation and maintenance. four.
