Description of the type, principle and description of common faults

Types, principle introduction and common fault analysis of differential pressure level gauge\level gauge
Working principle: The measuring principle of the differential pressure level gauge uses a steel pipe to connect the positive pressure end of the differential pressure gauge to the bottom of the liquid to be tested, and the negative pressure end to the gas phase, according to the hydrostatic principle; the differential pressure liquid level change The feeder works by the principle that the static pressure generated by the liquid column also changes when the liquid level in the container is changed.
Scope of application: It is suitable for the measurement of tank liquid level in petroleum, chemical, electric power, light industry and medicine industries. One use limit: the density of tanks with relatively large density and temperature changes, the accuracy is greatly affected, if any Scale or crystallize, so the scale or crystal adheres to the transmitter module, the transmitter is very sensitive, and the measurement medium is required to be pure
