Embodiment Construction

[0010] In order to make the object, technical solution and advantages of the present invention clearer, the online density analyzer of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0011] Such as figure 1 As shown, the online density and concentration analyzer 1 of the present invention includes a sensor measuring device 2 and a processing display device 3 .

[0012] Wherein, the sensor measurement device 2 includes a first differential pressure sensing diaphragm 21 , a second differential pressure sensing diaphragm 22 , a sensor 23 , a first ultrasonic probe 24 and a second ultrasonic probe 25 . Due to the use of the sensing diaphragm for density measurement, it has high sensitivity and high acquisition accuracy. The ultrasonic probe is used to quickly correct the change of the medium density, which can improve the measurement accuracy of the fluid density.

[0013] The first differential pre...

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a density analyzer. Background technique [0002] At present, density analyzers are widely used in petrochemical, mineral processing, dredger and other industries. In the prior art, ordinary density analyzers need to use radioactive sources for measurement. This type of ray densitometer has potential safety hazards, and the procedures for purchasing and scrapping radioactive sources are complicated, and the maintenance of equipment is frequent and complicated. In addition, ordinary density analyzers have pumps and elbows in the pipeline, which are placed inside the pipeline to be tested, and the pulse interference signal generated will have a great impact on the accurate measurement of fluid density. In addition, conventional ray densitometers cannot perform effective measurements when measuring semi-artesian or partially full pipes in slurry pipelines. Contents of the invention [0...
