Description

technical field

[0001] The invention relates to a liquid level transmission device, in particular to a liquid level transmission device for an oil storage tank. Background technique

[0002] At present, in the process of oil collection, most oilfield enterprises temporarily store the oil sprayed or sucked out of the oil well in the oil storage tank next to the well. The oil liquid level in these numerous oil storage tanks distributed in the field It is an important parameter in oil production. Accurate monitoring of liquid level is of great significance to the automation and safety of oil field production process. There are many kinds of existing liquid level monitoring equipment, such as an "environmental state measuring instrument" disclosed in US 2008 / 0092647A1 published on April 24, 2008. The environmental state measuring instrument is intended to monitor the liquid level in the liquid tank in a timely manner. It is composed of an electrically connected liquid level sen...
