Applicability Analysis of Electrical Remote Differential Pressure Level Transmitter
Differential pressure level transmitters are widely used in measuring liquid levels.When the distance between the upper and lower flanges is large,the capillary length used in the dual flange differential pressure level transmitter is too long,the measurement error,hysteresis,and other uncertainties of the instrument will be increased.The traditional solution for excessive flange spacing is introduced.The application places where ERS type differential pressure level transmitter is suitable to replace RS type differential pressure level transmitter are mainly discussed.Through comparative experiments,two types of transmitters are simulated under the same working conditions,and their measurement performances are compared.The data shows that ERS type dual flange differential pressure level transmitter has certain advantages over RS type differential pressure level transmitter in working conditions such as long distance,large differential pressure,small static pressure and large temperature difference.The applicability range and application suggestions of ERS type differential pressure transmitter are proposed finally based on data analysis.
