Abstract
The invention discloses a liquid measurement transmitter. The liquid measurement transmitter comprises a transmitter body upper end, a transmitter body middle end and a transmitter body lower end which are fixed sequentially through argon arc welding, wherein the transmitter body lower end comprises an O ring arranged at a joint of a base and a water guide head. The liquid measurement transmitter adopts split-structure connection, technically adopts the argon arc welding technology and the O ring made of a special material and further adopts a special regulator circuit for a PGA 309 sensor, so that the airtight performance and the corrosion performance of the product are improved by the aid of the structure, and meanwhile, the accuracy and signal stability of the liquid measurement transmitter are improved.
