Orifice meter scale hardware and software in the process of measuring error causes analysis

Abstract: the orifice meter scale hardware and software in the process of measuring error causes analysis information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Due to the differential pressure transmitter of mobile devices: what's the weather like in xinjiang many problems the temperature difference between the larger connection part of the pulse line is still the field conditions, the orifice meter measuring error analysis used in the field of the orifice flowmeter is this, hole section is a wrong. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the orifice meter scale hardware and software in the process of measuring error causes analysis for details. Due to the differential pressure transmitter many problems of mobile devices: what's the weather like in xinjiang part of a larger temperature difference between the connection of the impulse line is still under the condition of the field, the orifice meter measuring error analysis used in the field of the orifice flowmeter is this, hole part is the possibility of an error, stay focused. Possible and can be measured on the wall erosion degree of corrosion of the board, especially on the edge of the entrance to a right Angle, in the use of separation, despite the filtration unit and dust, the diaphragm, the formation of mining gas emissions factors change, the well board, the necessary criteria, is beyond the estimated flow measurement uncertainty of the measuring tube corrosion at right angles to the lining of the comparison, and the radius of the edge of the entrance is a particularly serious we alleles. Orifice meter's software, hardware, or go on a brief analysis of less. , such as gas flow rate, we have been using the standard orifice meter measuring gas composition, differential pressure, pressure, temperature and flow rate. Any deviations from the design process is a common parts, zui execution process of the actual value, this is our concern zui many questions. In most cases, the added value of the design process, the brief analysis of the actual operation, the flow rate value is low, the main reason is as follows. The reliability of the reference error by measuring the differential pressure transmitter. Differential pressure gauge error distribution: when the system work in less than 50%, 1% of the differential pressure measuring relative error of 1% to 6% to 3% of the traffic. As a function of the Reynolds number in the same flow rate value, it is necessary to the Reynolds number flow value deviation, which may lead to a change in discharge coefficient inevitably lead to changes. So, to produce flow value and the actual operation, the effect of design value deviation. Medium temperature and pressure deviates from the value of the design, the process ( Including gas and liquid) The dielectric fluid mass flow rate of the design conditions, design calculation of the throttle device, the specific conditions, many parameters of the main parameters, pressure and temperature. According to the dielectric fluid density is constant this particular conditions ( Temperature, pressure, etc. ) , and the main parameters, the actual execution of the media, the movement of the fluid temperature, from the design value of pressure you will inevitably change the density of fluid medium. In the culture medium, the variation of the density of the fluid flow value is very intuitive. Processing operations transformation according to the fluid density, and read the meters, volume flow rate under normal condition are given. Change the density of its dielectric fluid, conversion relationship. The effects of the equipment the actual execution of the flow measurement aperture deviates from the value of the design value. Improper open orifice plate processing size, does not comply with the design requirements. Gradually balance the relationship between the valve, three valves, gas flow, because there is a small leakage, this is possible, in order to reduce the pressure tube transmitter output signal is low differential pressure gauge. Non-return valve 3 in the high and low pressure valve is closed. I will continue to slow until it reaches the balance is zero, the output valve leakage, the output of the instrument, we won't change. Incorrect installation? 吗? An error occurred. Reduce instructions orifice flow meter, flip, and displacement of pipeline layout, and pipeline installation errors from the initial layout is that it can not meet the required length of straight pipe sites, the main reason for the universality. The error produced by the instrument itself. Example: position eccentric pressure, welding, welding highlight the entrance of the hole, hole thickness error, stair accessories throttle, eccentric vertical sharpness, roughness on the surface of the orifice upstream end, in the size of the annular chamber steps, take the hole pressure displacement of cuttings, processing of non-standard or blocked. Other errors. Orifice meter hardware and software in the process of measuring error causes analysis become to store gas in the work place and sales zui common error ( Such as deformation) Upstream on the upstream face of dirt, dirt deposition sounding pipe, side to side inlet depressing and bending orifice, such as natural gas, and corruption, orifice plate corrosion damage wound pipe hardware problems, these rings for long-term use of gas, the gas permeability of work area, so as to formulate effective measures, hardware maintenance holes filling and sealing, oil timely communication to the corresponding part of the inspection and maintenance on a regular basis orifice plate: it is relatively easy to find and solve it. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
