Original E+H level gauge * supply

E+H level gaugeIt is an instrument used in industrial process measurement and control systems to indicate and control liquid levels. Liquid level gauges can be divided into two categories based on their functions: base type (on-site indication) and remote transmission type (remote display and control). Remote level gauges usually convert the on-site liquid level conditions into electrical signals and transmit them to the places that need to be monitored, or use liquid level transmitters with display instruments to achieve remote display purposes; The control of liquid level is usually achieved through positional control. E+H level gauges typically consist of three parts: sensors, converters, and indicators. A liquid level gauge with control function and a setting mechanism.

E+H level gaugeNormally, a mass flow meter is used to measure hydrogen gas, but it requires reducing the diameter to increase the flow rate, resulting in significant pressure loss. Additionally, due to the fast flow rate at the outlet of the flow meter, there is a possibility of danger, and a long straight pipe section is required at the back end of the flow meter to restore the flow rate. Flow meters are widely used in industries such as coal chemical, polycrystalline silicon, and power. It has stable operation, simple structure, long service life, moderate accuracy, and low maintenance, and can be used for measuring various media. Through performance analysis of rectangular flow meters, the E+H level gauge shows that its measurement accuracy is about 4 times that of traditional throttling devices, and its long-term pressure loss is about 1/3 of that of traditional throttling devices. At the same time, the flow meter requires a small straight pipe section ZUI, which can reach 1.5D, thus eliminating a large number of straight pipe sections. Due to the lack of moving parts, installation and maintenance are relatively easy.

E+H level gaugeThe flow state smoothly enters the throat from the contraction section, which can greatly reduce wear. At the same time, the rectangular flowmeter adopts a streamlined throttling channel with a throat of appropriate length, which plays a rectifying role and effectively flattens the fluctuations of the fluid. In addition, the pressure recovery section at the rear extends this streamlined channel, so that the entire flowmeter will not generate vortices and vibrations inside, avoiding wear caused by vortices. The rectangular flowmeter can be used continuously for 3 years with unchanged measurement accuracy, and its service life is more than 4 times that of the wedge-shaped flowmeter. The special structure of the flowmeter ensures that the flow coefficient is linear and stable over a wide range of Reynolds numbers, making the E+H level gauge accurate for both high and low flow rates. In the polycrystalline silicon industry, hydrogen is an industrial gas that is difficult to measure. The hydrogen feed rate of the reduction furnace is controlled by a pre-set ratio to regulate the feed control valve. If the measured flow rate fluctuates greatly or the flow rate is small and cannot be measured, it will cause the regulating valve to frequently operate, thereby affecting the quality of the silicon rod, and even causing the E+H level gauge to stop abruptly due to rod reversal; If the flow measurement is not accurate, it will lead to incomplete blowing and replacement, which poses a safety hazard.
