Metal tube flow meter scale pointer jitter analysis of the causes

Abstract: metal tube flow meter scale pointer jitter analysis information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Metal pipe flow meter bottom-up measured medium flowing through the measuring tube, float the differential form from the top and bottom side of upward force, when the float upward force is greater than the baptism by float weight in the fluid, float up, clearance area increase, annular fluid flow velocity. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a metal tube flow meter scale pointer jitter cause analysis, the article details. Metal pipe flow meter bottom-up measured medium flowing through the measuring tube, float the differential form from the top and bottom side of upward force, when the float upward force is greater than the baptism by float weight in the fluid, float up, clearance area increase, annular fluid velocity drops rapidly, the differential pressure reducing float up and down the end, acting on the float upward force as is reduced, until the lift float weight balance and immersed in the fluid, the float and stable position in * and float the discretion of the position that corresponds to the size of the measured medium flow. Move up and down in float float the built-in magnet steel, medium, magnetic field changes with the movement of the float. Through a magnetic sensor to magnetic field changes into electrical signals, the modulus conversion, digital filtering, temperature compensation, microprocessors, digital to analog conversion, LCD, switch control output, to show the instantaneous flow and cumulative flow size and control. A pointer jitter and metal pipe float flowmeter: 1. Metal pipe flow meter pointer slightly shaking: generally caused by fluctuations in medium. Can be used to increase the damping ways to overcome. 2. Pointer to moderate jitter: generally caused by medium flow state. Is often caused by unstable operating pressure of medium for gas. Can use voltage or current regulator devices to overcome or increase the gas flow meter damping. 3. Due to pointer flog: medium pulse, pressure instability or a user given gas pressure, temperature and flow of the operating state does not accord with the actual state of metal tube float flowmeter, a bigger difference caused by flow meter range. Second, the metal flow meter pointer jammed tube flow meter pointer is jammed, may be because the metal flow meter was first used in open valve too fast, the float fast upward shock stop, stop deformation caused will float. But does not rule out due to float guide bar with different heart, stop ring float jammed. Processing instrument can be removed, the deformation of plastic surgery to stop off, and check whether with guide bar work, such as different heart can be calibrated, then float installed, push float, feeling float up and down unimpeded card can, in addition, the metal flow meter installation must be vertical or horizontal installation, cannot tilt, otherwise easy to cause the card table, and also brings to the measurement error. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
