LKZN type intelligent drilling mud control device, mainly used for drilling system drilling mud tank storage monitoring. The instrument consists of two parts. One part is the liquid level transmitter, which transmits the liquid level signal to the secondary instrument. The other part is an intelligent display control instrument that adopts wide-angle, high-brightness TFT true color liquid crystal, ultra-large capacity FLASH and intelligent embedded high-reliability U disk backup. The instrument converts a certain path of liquid level signal into the existing drilling liquid storage capacity (m3) and displays the storage capacity. At the same time, the storage capacity of each path is accumulated and displayed, and the upper and lower limit alarms are carried out according to the storage capacity requirements of each path, so as to monitor the drilling liquid storage capacity of the drilling system at any time.
