Abstract: the cause the orifice meter scale six major cause of the error information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. 1, orifice plate hole and pipe assembly different heart flow time, due to the construction personnel irresponsible, may cause the orifice orifice and pipes of different heart, lead to measure error. 2, orifice meter pipe water pipe, water will change the orifice flow. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the error caused the orifice meter scale of six big reasons the article details. 1, orifice plate hole and pipe assembly different heart flow time, due to the construction personnel irresponsible, may cause the orifice orifice and pipes of different heart, lead to measure error. 2, orifice meter pipe water pipe, water will change the geometric characteristics of the orifice flowmeter metering device, so as to affect the accuracy of flow measurement. 3, orifice plate deformation or scaling. Orifice plate in the process of transportation, installation, due to the construction personnel is not strong sense of responsibility, is likely to cause orifice plate deformation; Orifice meter after long time use, scaling on the surface orifice, making smaller orifice opening size, cause measurement error. 4, straight pipe before and after the orifice meter is not in conformity with the requirement of straight pipe before and after the orifice plate is used in order to guarantee the stability of the flow of the fluid in the pipeline, but owing to lack of straight pipe length or often turn on process piping, bifurcate, meet resistance, make the fluid from stable disturbance, resulting in measurement errors. 5, orifice plate piece of upstream and downstream face damaged or orifice flange gaskets protruding pipe orifice or internal transportation in the process of the construction personnel to install orifice, easy to cause damage or orifice flange gaskets protruding of face of the upstream and downstream pipe, which may lead to a measurement error. 6, orifice upstream and downstream face pack. Due to carelessness, construction personnel will orifice plate loading, the direction of gas flow and the orifice plate, resulting in measurement errors. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
