Model :CS-MI
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.
The servo level meter has the functions of measuring liquid level, density and oil-water interface. It can be connected to multi-point average thermometer, pressure transmitter, tank side display and other equipment. It is the core of the automatic measurement management system of the whole storage tank.
It is suitable for places that need accurate measurement of liquid level, including oil depot, refinery, trading station, pipeline station, chemical plant, etc.
