Foreword

This standard is GB/T 3214-1991 "Determination of pump flow," the amendment. Compared with GB/T 3214-1991 major change Of the following. --- Structural arrangement according to the principle of the flowmeter to measure general requirements, installation requirements, flow measurement uncertainty and other content prepared by; --- Adjust the content of the documents cited in Chapter 2; --- Increased Chapter 3. Terms and definitions; --- Increased flowmeter measurement principle; --- "Standard plate, the standard nozzle and standard Venturi nozzle" to "plates, nozzles and venturi nozzle"; --- Increased plates, nozzles and venturi nozzle flow calculation formula; --- Increasing the definition and calculation formula for discharge coefficient of orifice plates, nozzles and Venturi nozzles, see 3.6 of this standard; --- Introduction of the GB/T 2624 in the shortest length of straight pipe orifice plates, nozzles and Venturi nozzle required (not including an additional 0.5% Degree of certainty); --- Provisions of the orifice upstream pipeline connections the maximum permissible level values, see 5.3.2.1.2 of this standard; --- Increased orifice plates, nozzles and Venturi nozzle flowmeters use restrictions; --- Improve the plates, nozzles and venturi nozzle flow meter installation requirements; --- Improved orifice, take the pressure nozzles and Venturi nozzle apparatus and to take pressure meter; --- Added two flow regulator types. grid type flow regulator and radial vane type flow regulator; --- Delete the original standard contents 4.2.5. β α relationship value and flow coefficient 4; --- Increasing the number of requirements measured flow rate accuracy can be achieved with a method and container to meet this accuracy; --- Traffic system corrects for the discharge coefficient; --- Provides containers, weighing, commutator, timer and content assist measurement methods; --- Added "8.1 Works"; --- Improve the content related to verification of the meter; --- Increased Chapter 9. electromagnetic flowmeter; --- Flow measurement uncertainty evaluation and expression has been amended; --- Fixed Appendix B, Table B. 1 "Design weir reference size" value; --- Appendix C will be changed to "Uncertainty Analysis Flow Measurement"; --- Added Appendix D "closed pipeline pumps use site used by the meter."
