LWY series - turbine flowmeter / Zibo Bai Si-Dongchi Control flowmeter

The basic performance parameters Measuring medium liquid (304 or 316 stainless steel, 2Cr13 steel or nickel and corundum Al2O3 not have a corrosive mm diameter threaded connection 4,6,10,15,20,25,32,40 flange (25) , (32), (40), 50,65,80,100,125,150,200 (DN25-40 conventional threaded connection, flange connection to be special order) Accuracy class 1, 0.5 (specific traffic segments can be up to 0.2) ± 0.2% of indicated value Repeatability medium temperature -20 ℃ ~ + 120 ℃ Ambient temperature: -20 ℃ ~ + 55 ℃, humidity: 5-95% Protection class IP67 Explosion levels ExmⅡCT6 ExdⅡBT6 12VDC 24VDC power supply or battery-powered (3.2V 10AH) output signal pulse output voltage amplitude: high ≥8V, low ≤0.8V transmission distance ≤1000 meters standard current 4-20mA DC straight pipe downstream of the flowmeter upstream ≥20DN ≥5DV Features 1, the sensor is a push-type carbide bearing stop, not only to ensure accuracy, improve wear resistance, and has a simple structure, strong and easy accessibility features 2, a variety of transmitter models: three-wire pulse output; wire 4 ~ 2OmA current output; site display and output 4 ~ 2OmA; battery-powered, etc., for different occasions 3, intelligent processing: multi-point non-linear meter factor correction to ensure full scale precision 4 meter factor, cumulative flow value fall power to maintain, works years without loss of fluid through the sensor housing, the impeller blades and the flow of dry angled, the blade having a fluid momentum rotational torque to overcome the friction torque after rotating blades and fluid resistance, the torque balance After the speed and stability, under certain conditions, the velocity is proportional to the rotational speed, since the blade has a magnetic permeability, which is in the signal detector (by the permanent magnet and coil) of the magnetic field, the magnetic lines cutting blade rotates, periodically change the coil of the magnetic flux, so that across the coil induces an electrical pulse signal which is amplified shaping amplifier is formed with a certain level of continuous rectangular pulse wave, can be remote to the display instrument, showing the instantaneous fluid flow or total The amount of traffic within a certain range, pulse frequency f of fluid flowing through the sensor (instantaneous flow rate Q) is proportional to the flow rate is calculated as follows: LWY Series turbine flowmeter has a simple structure, lightweight, high accuracy, good repeatability, reaction sensitive, installation and maintenance easy to use features typically used in water, diesel fuel, methanol and other no impurities, no strong corrosive liquid, if there are special features and display instrument, can also be quantitative control, excessive alarm is flow measurement and saving the ideal instrument.
