Detailed Product Description: | Hebei Hongye Nanjing Branch vortex flowmeter uses: widely used in petroleum, chemical, power, light industry and other sectors of industrial pipeline Hebei Hongye Nanjing Branch vortex flowmeter to measure the flow of liquids or gases. Also be used for urban water supply, heating, boilers, water supply, medical industry fluid pipe flow measurement sensor material for 1Cr18Ni9Ti. Explosion-proof type LUGB line vortex flowmeters, using the security proof technology. Battery-powered vortex flowmeter, the proof mark "Ex ia II BT4", for not higher than Class II Class B 0, Zone 1, Zone 2 contains T1 ~ T4 dangerous places rely on the safety barrier for electricity vortex flowmeter, the proof mark: "Ex ia II BT5", applicable to Class II Class B Zone 0, Zone 1, Zone 2 contains T1 ~ T5 dangerous places. The vortex flowmeter characteristics: ① simple structure, no moving parts, easy installation and maintenance, long life. (2) the pressure loss is small, wide measuring range ③ piezoelectric stress detection body is installed in a separate the shedder rear, reducing the impact of the media in stolen goods (4) sensing element is not directly in contact with the measured medium, especially suitable for the harsh environment of flow measurement ⑤ The field can also be remote, but also with computer systems networking. The Vortex Flowmeter structure: LUGB vortex flowmeter detector, the two major components of the converter. Detector by the table body, vortex shedder detect body. Converter by the housing and the switching plate (voltage pulse signal, standard current signal or field display). Vortex flowmeter works: LUGB vortex flowmeter, Karman vortex street principle, steam, gas and low-viscosity liquid flow meter used to measure. When the fluid flow through vertical shedder, alternately in both sides of the rear two whirlpool flow measured media, called Karman vortex street. Vortex Flowmeter parameter nominal diameter Dn25 DN40 DN50 DN65 DN80 DN100 DN125 DN150 DN200 DN250 DN300 the measured medium gas liquid vapor nominal pressure 2.5Mpa (> 2.5MPa consultation supplier) 1.5 Ambient temperature scene of a precision grade liquid gas direct-reading sensor: 0 ℃ ~ 55 ℃; the pulse signal sensor: -20 ° C to 70 ° C measured medium temperature -20 ℃ ~ +160 ℃ 100 ℃ ~ +280 ℃ 100 ℃ ~ +350 ℃ output signal the type ① voltage pulse signal (three-wire): low level ≤ 1V high ≥ 5V (2) (m3 / 4 to 20 mA standard current signal (two-wire): conversion accuracy of ± 0.5% F · S (3) the scene to direct reading (no output): instantaneous flow 5 h or kg / h) (m3, Nm3, kg, T) ④ scene straight read the cumulative flow rate of 10 or 8 with 4 ~ 20mA standard current signal (two-wire) Power supply 24V DC power supply (Note: the security proof by barrier-powered). Apply with a voltage pulse signal or a standard current signal output sensor (1) two built LR6 1.5 × 2 Nanfu battery explosion-proof special ⑵ 3.6V; 7.5Ah lithium battery design battery life 2 years (dedicated) suitable for on-site explosion-proof mark of any signal output sensor battery-powered direct reading: Ex ia II BT4; external power supply type: Ex ia II BT5 material 1Cr18Ni9Ti (the agreement supply of other materials) |
