Detailed explanation of technical parameters of vortex flowmeter
2012-3-7 8:46:38

I. Overview:
,由我公司生产的LW—G、Z、D型流量传感器(“G”“Z”“D”分别代表高中低三种系列传感器,以下简称G型、Z型、D型),前置放大器和XSJ系列显示仪根据GB/T1314—91ZBN12005-89的标准组成。 LW type vortex flowmeter , LW-G, Z, D type flow sensors ("G", "Z", "D") are produced by our company, respectively representing three types of high, middle and low series sensors, hereinafter referred to as G, Z, D Type), preamplifier and XSJ series display are composed according to GB / T1314-91ZBN12005-89 standard. The sensor has high accuracy, high voltage resistance (G type), simple structure, easy installation and maintenance, long-distance transmission of output pulse signals, and beautiful appearance. It is widely used for the measurement of liquid volume flow of water and gas and industrial fluids, as well as chemical products, and it is mainly used for the detection and measurement of water in high and low pressure water injection systems in oil fields. The bearing is made of hard alloy, which is both anti-corrosive and wear-resistant. This product has two series for measuring liquid and gas.
Features:
具有G、Z、D型三种系列,并具有国内唯一的工作压力达到50Mpa的流量计。 ◇ LW vortex flowmeter has three types of G, Z, D type, and has the only flowmeter with a working pressure of 50Mpa in China. It is mainly used for the measurement of water injection volume in oil field water injection system. At the same time, it is also suitable for various high and low pressure water machine systems for flow detection.
◇ Using full hard alloy (tungsten carbide) shielded cantilever beam structure bearing, which integrates rotary bearing and pressure bearing, greatly improves bearing life, and can work in the medium with a small amount of sand and dirt.
◇ 1Cr18Ni9Ti stainless steel structure (2Cr13 for turbine), good anti-corrosion performance.
◇ Using samarium cobalt permanent magnet alloy as the signal detector, the output signal is strong and the magnetic stability is good.
◇ Wide temperature range, can work normally in the range of 0 ~ 120 ℃.
◇ Easy maintenance. The flowmeter has a self-rectifying structure, which is small and light, and simple in structure. It can be disassembled in a short time, and the internal cleaning is simple.
前置放大器: Third, the vortex flowmeter preamplifier:
◇ Types: ordinary amplifier (referred to as "I") and explosion-proof amplifier (referred to as "EX").
◇ Composition: It is composed of variable magnetic group converter and amplifying part. Explosion-proof amplifier is equipped with explosion-proof device.
◇ Signal transmission distance: The effective value is 1 ~ 250m.
◇ Working power: 12VDC, 24VDC
◇ Output signal: square wave, sine wave, 4 ~ 20mA.
◇ Amplitude: about 10V when + 12VDC power supply, about 20V when + 24VDC power supply.
◇ Mark of explosion-proof amplifier: dⅡBT3—T4
