The servo level meter is a high-precision measuring instrument that can measure liquid levels, density, and oil-water interfaces. It can be integrated with multi-point average temperature meters, pressure transmitters, and tank-side displays, serving as the core of the automatic measurement management system for storage tanks. With the help of accompanying management software, it can automatically convert standard density, VCF, volume, and mass. The meter also features high and low level alarms, density alarms, and water level alarms. It can be connected to systems such as SIS, PLC, and DCS and is widely used in oil depots, refineries, chemical tank areas, and pipeline stations.
