Description
Technical Field
[0001] The utility model relates to the technical field of differential pressure liquid level gauges, in particular to a protective structure for a differential pressure liquid level gauge dial. Background Art
[0002] The differential pressure level gauge is an instrument that calculates the liquid level (differential pressure) of an object in a container by measuring the pressure difference at two different points in the container. ERS electronic remote sensing technology solves the common problems of level measurement on high-type containers and towers. The ERS electronic remote transmission system uses two directly mounted 3051S pressure transmitters instead of a single differential pressure transmitter using a capillary tube. The two pressure transmitters measure the pressure values on the high and low pressure sides respectively, and calculate the differential pressure through the main table in the two pressure transmitters; it is transmitted back to the host system or DCS system by using a standard two-wire 4-20mA HART signal. In addition to measuring the differential pressure, the pressure values on the high and low pressure sides can be output at the same time, and the differential pressure can be directly converted into a liquid level value output display.
