Zusammenfassung
(PT)
método para operar um medidor de fluxo, e, medidor de fluxoum método para operar um medidor de fluxo é provido. o medidor de fluxo inclui um acionador e sensores de desvio acoplados ao tubo de fluxo. o acionador é adaptado para vibrar o tubo de fluxo em resposta a um sinal de acionamento. o método compreende configurar uma voltagem de desvio alvo e medir uma temperatura de medidor de fluxo. o método ainda compreende gerar uma voltagem de desvio alvo compensada em temperatura e controlar o sinal de acionamento para manter uma amplitude de tubo de fluxo compensada em temperatura
