Henghe Vortex Flowmeter Manual

Hengrove vortex flow meter consists of sensors and inverters. It is a volumetric flowmeter developed according to the principles of Kamen vortex, for measuring the volume flow or mass flow of the gas, steam or liquid, under standard conditions. The card door demonstrates that when H / L = 0.281 (H is the width between the two split edies, the vortex column is stable when the distance between the two adjacent rotation modes). The working principle of the flowmeter is: when fluid passes through a barrier or special component, flow oscillation is generated, reflecting the flow by measuring its oscillation frequency. The flow meter is mainly used in industrial pipe medium fluid, such as flow measurement of media such as gas, liquid, and steam. The cause of the vortex is that when the fluid is blocked by a non-flow column perpendicular to the flow direction, a significant vortex is produced on both sides of the cylinder to form a card door vortex. The formation of eddy currents is related to the number of Rayano of the fluid. Henghe vortex flowmeter excellent features: (1) The vortex flow meter is simple and secure, and it is an indispensable part of many industrial industries. (2) The flow meter is widely used, such as liquid, gas, steam, and partially mixed fluid. (3) There is no movable part, high reliability, and long-term operation is very reliable. (4) Compared with differential pressure, the float flow meter, the accuracy is high, generally can reach about ± 1% R. (5) The range width is 10: 1 or 20: 1. (6) The detection sensor does not directly contact the medium, the performance is stable, and the life is long. (7) Small compression, approximately 1/2 to 1/4 of the aperture flow meter. (8) The pulse signal proportional to the flow rate is applied to the total meter, no zero point migration. (9) In a certain Renault number range, the output frequency signal is not affected by fluid (density, viscosity) and component, and the instrument coefficient is only related to the shape size of the vortex, and the shape size of the pipe can be verified in a typical medium. It is suitable for various media. (10) The corresponding vortex detection technique can be selected for different objects. Henghe Vortex Flowmeter Installation Skills: 1. First, we must ensure that the flowmeter is tube measurement. 2. It is recommended to install vertical flow meter so that the liquid flows from the lower incision. 3, the flowmeter should be installed through the high voltage area of the entire system to ensure a certain back pressure. 4. Guarantee the front and rear straight pipe segments required for the flowmeter. 5, the flowmeter should be installed downstream of the pump, upstream of the valve. 6, the inner diameter of the pipe must be slightly more than 2mm, or equal to the inner diameter of the flowmeter. 7. Pay attention to the installation of the instrument when steaming. Editor in charge: WV
