Abstract: the intelligent vortex flow meter scale pipe flow meter no output should be how to solve the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Intelligent vortex flowmeter is mainly used for industrial piping medium fluid flow measurement, such as gas, liquid and vapor, and other media. No moving mechanical parts, so high reliability, small amount of maintenance. Instrument parameters can be long-term stability. Using piezoelectric stress type vortex flowmeter. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the intelligent vortex flow meter scale pipe flow meter no output should be how to solve the article details. Intelligent vortex flowmeter is mainly used for industrial piping medium fluid flow measurement, such as gas, liquid and vapor, and other media. No moving mechanical parts, so high reliability, small amount of maintenance. Instrument parameters can be long-term stability. Vortex street flowmeter using piezoelectric stress sensor, high reliability, can be in - Working temperature of 20 ℃ ~ + 250 ℃ within the scope of work. ( 1) May be the cause of the problem is the power failure or power supply connection. So to test for a conform to the requirements and the power supply voltage polarity is correct. Such as the current output type vortex flowmeter, if there are power reverse polarity, the output current 0 ma rather than 4 ma ( 2) Likely the cause of the problem is connecting cable disconnection or connection error. Need to detect the line was clear, such as defective, wiring and testing. ( 3) May be the cause of the problem is the power supply ripple coefficient is too big. Check can use a filter capacitors, general requirements capacitance & sup3; 100μ F,50V。 ( 4) May be the cause of the problem is amplified board MouJi vortex flowmeter is faulty. Amplifier input, the output waveform can be observed, or into the human body induction signal from the input end, observe the output changes. If the output does not change, amplifier don't work properly. Also can use in the actual repair to check some other types of flowmeter motherboard replacement site. Determine the amplification plate has a fault, shall be replaced. ( 5) May be the cause of the problem is vortex flowmeter sensor body damage. Detection method first increase traffic, put the vortex board in the same type of vortex flowmeters, such as ruled out the mainboard failure, check body. Vortex flowmeter in body damage appeared in the steam measurement system, more too fast because the technology personnel to open the valve, the high temperature and high pressure water vapor condensed water entrainment of vortex occurred in severe body, result in the damage, which is often said & other; Water hammer & throughout; Phenomenon. So to enlighten pour the row of condensed water and then slowly open the steam valve, avoid damage to the whirlpool. ( 6) May be the cause of the problem is pipe flow is too low, not into the measurement range. Can increase the flow meter response. Beside the pipe near the vortex street flowmeter regularly continuous percussion, regardless of the type of vortex flowmeter are flow display will appear. If the medium to be measured for liquid, zui atc test well, because the liquid itself is damping device. Troubleshooting method is to change the size smaller flow meter or in the case of process conditions to allow more traffic. ( 7) Likely the cause of the problem is whether the gap between body and the shell was fine particles stuck. This kind of phenomenon generally appear in normal work after shutdown and boot. If so, in confirm switching amplifier and body all intact, especially the measured medium is liquid, can generally be considered to be the failure. Processing method is if the production process conditions allow, as far as possible to open big traffic, with a wooden or rubber hammer welding vertical stroke, on the stage at the bottom of the flowmeter to negative pressure produced by high velocity to take away small solid particles. If the site allows removal of cleaning, can remove the body, but it requires the familiar with the structure of the flow meter, especially the sealing gasket and clamp screw etc. , must be strictly in accordance with the instructions required to install. At the same time attention should be paid to remove after reinstalling the happening of the body, could lead to some changes on the discharge coefficient, although the change is not big, but need to be modified. ( 8) Manual controlled vortex street flowmeter testing parameter is set if there is a mistake, if you have, be corrected. Haynes automation instrument is a company specializing in the production of electromagnetic flowmeter, turbine flowmeter, vortex flowmeter, magnetic flap liquid level meter, thermocouple, heat resistance, bimetallic thermometer and all kinds of pressure gauges, etc. , as well as the production of various non-standard meter manufacturers, the company has advanced management level, the modernization of professional production equipment, precision calibration device. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
