Nitrocompound fertilizer is an important fertilizer in agricultural production. It is produced by three methods, i.e. melt granulation, partial slurry, and solid agglomeration. Of these three methods, the melt granulation method is the most common and frequently used method
The melt granulation method mainly consists of adding compound fertilizer raw materials such as potassium sulphate, potassium chloride, ammonium phosphate, and explosion-proof additives to the molten ammonium nitrate to form a mixed soluble body.
In production, the level measurement and control of the melt tank and intermediate tank are important parameters for this method. Therefore, what kind of radar level meter is very critical and necessary for molten ammonium nitrate level measurement?
To solve this problem, it is necessary to first understand the working conditions of molten ammonium nitrate level measurement.
At concentrations above 98%, molten ammonium nitrate is susceptible to crystallization. In order for the molten ammonium nitrate not to crystallize, the temperature in the tank needs to be guaranteed to be around 175°C. From this point of view, the radar level meter needs to be of the high-temperature type.
When the temperature is too high, the molten tank is prone to vapor and this working characteristic is not suitable for contact radar level meters, so the positioning should be in non-contact radar level meters.
Zero Instrument 26GHz high-frequency radar level meter RD902T, suitable for temperature, pressure, and corrosion-resistant liquid level, anti-vapor, and crystallization.
As to whether this radar level meter is suitable for your working conditions, also depends on the tank range, the presence of obstacles, and other influencing factors.
