No presente trabalho, foram realizados vários experimentos utilizando orifícios integrais em tubos de PVC de 1⁄2 polegada, para verificar a influência da rugosidade do tubo, da excentricidade do furo e da geometria do orifício nas medições de vazão. Experimentos adicionais foram feitos para verificar influências de fabricação e a interferência da rugosidade do tubo sobre a operação do equipamento. Os coeficientes de descarga foram obtidos em função do número de Reynolds e, posteriormente, comparados entre si e com a literatura (fabricantes e normas). Os resultados mostraram que os orificios concêntricos com borda em canto vivo permitem operação em uma ampla faixa de Reynolds, além de apresentarem um processo de produção mais barato e uma boa precisão. Uma equação representativa do coeficiente de descarga foi proposta para este tipo de placa / Integral orifice is an industrial flowmeter useful for small diameter lines (typically up to 38 mm), which provides a very precise alignment. In the present work, experiments have been performed using integral orifices in 1⁄2 inch PVC pipes, in order to check the influence of the tube roughness, the eccentricity of the hole and orifice geometry in the flow measurements. Additional experiments have been carried out to verify the influence of the manufacturing process and the roughness in tubes on the equipment operation. Discharge coefficients have been obtained for the different orifices as a function of the Reynolds number. Results have been compared to each other and with data from the literature (manufacturers and standards). Results show that concentric plates with square edge permit operation in a wide Reynolds number range, allied a cheaper manufacturing process and a good accuracy. A representative equation for the discharge coefficient of such a plate has been determined
