1, measuring the temperature of the medium radar level meter measurement temperature range is -40~250 degrees, the medium in this temperature range, radar level meter can work normally. When the temperature is lower than -40 degrees, the LCD screen cannot work normally.
2, measuring the pressure of the medium Ordinary radar level gauge measuring pressure range is 0~4MPa.
3, the physical characteristics of the measuring medium need to determine the physical characteristics of the measuring medium, including the corrosiveness of the medium, whether it will adhere, whether it will crystallize, etc., the selection of different models need to be selected according to the specific physical characteristics.
4, the process connection specifications need to implement the specific process connection specifications on the tank, if it is threaded connection, the radar level meter needs to be threaded connection.
If it is a flange connection, it is necessary to implement the accurate flange specifications. Only after determining the flange specifications can the radar level meter match the corresponding antenna size. If the flange specifications are not accurate, the instrument cannot be installed on site.
5, tank mixing specifications When there is mixing in the tank, it is necessary to implement the specific mixing specifications, including several layers of fan blades, the distance between the fan blades and the tank wall, the radius of the fan blades and other parameters. When installing the radar level gauge, avoid the stirring fan blade as much as possible.
6, flange nozzle height Flange nozzle height must be determined the exact size, because when the radar level meter is installed, the antenna must reach into the tank, that is, the radar antenna length must be greater than the nozzle height. If the radar antenna length is less than the nozzle height, the measurement effect will be greatly reduced.
7, tank range Tank range is directly related to the accuracy of the instrument parameters, must be accurately determined.
