Oval gear flow meter for measuring highly viscous media, products widely used in petroleum, petrochemical, natural gas, chemicals, paper and other industries, to measure small flow measurement for small diameter. The main advantages: ◆ diameter from 10 ~ 150mm; ◆ shell material has a variety to choose from: aluminum, stainless steel and high-pressure stainless steel, PPS, bronze; ◆ bearing materials have a variety to choose from: ceramics, bronze, Hastelloy, carbonized material, PPS, stainless steel; Material ◆ axis: 316 stainless steel; ◆ O-rings are made of VITON, fluorine rubber, stainless steel, Teflon for selection; ◆ turndown ratio of 10: 1 up to 50: 1; ◆ accuracy of ± 1% and ± 0.5% are two, repeatability ± 0.03%; ◆ When installing a straight pipe segment requirements: 5D + 3D, the need to install filters; ◆ viscosity up 1,000000CP; ◆ pressure ratings up to 551bar; ◆ temperature rating up to -10 ~ 60 ℃; an overview of oval gear flow meter for liquid flow in the pipeline for continuous measurement of precision measuring instruments. It has a measuring range of large and small pressure loss, strong viscosity adaptable, capable of measuring temperature, high viscosity liquids, calibration convenient, easy to install and many other advantages, the volumetric flowmeter is representative of the product. ZX-LC Series oval gear flow meter, equipped with live pointer shows a cumulative count of the character wheel device, the liquid flows through the pipe can be displayed directly within the cumulative flow. Particularly suitable for measuring the finished oil medium. Widely used in flow measurement of non-corrosive medium petroleum, chemicals, chemical fiber, transportation, commerce, food, medicine and hygiene and other industrial sectors. Second, the principle structure LC oval gear flow meter consists of flow transmitter and counting mechanism. The main part of the transmitter is fitted with a pair of oval gear rotor of the metering chamber and sealed coupling components. Counter mechanism contains speed reduction mechanism, precision adjustment mechanism, the counter and the electrical pulse sender and other components. There are a pair of metering chamber and oval gear cover crescents constitute the beginning of a cavity as a unit of measure traffic. Oval gear flow meter by the pressure difference between the inlet and outlet to promote and rotation, so keep the liquid at the inlet of the beginning of a moon-shaped cavity after the measurement to the exit of each turn is the amount of liquid flowing figure crescent chamber four times the total number of oval gear coupling seal rotate, and the rotation speed of transfer to the counting mechanism, through the pointer display and the word round accumulation, you can know the total amount of liquid through the pipeline. Counting mechanism can be installed with a pulse sender That letter became oval gear flow meter, and the Company electric display instrument can achieve remote (quantitative, cumulative, instantaneous, and other functions) automated measurement Third, general technology Parameters 1. The main component materials and nominal 2. Accuracy grade 0.5, 0.2 (generally medium temperature -10 ℃ ~ + 60 ℃). 3. The use of medium temperature :( ambient temperature -10 ℃ ~ + 60 ℃). -10 ℃ ~ + 60 ℃; high temperature adjustment, plus high-temperature thermal tube up 60 ℃ ~ 200 ℃. 4. Remote Display scene proof grade: ExiaⅡCT5, dⅡBT4. NOTE: When the measured liquid temperature is higher than 80 ℃, the maximum flow meter for meter 90% of the original maximum flow, minimum flow should be 120 percent original Wenzhou meter oval gear flow meter minimum flow, Wenzhou gear flowmeter Yueqing flowmeters
