Measuring tube for analyzing sand content of crude oil

The utility model relates to a measuring tube for analyzing sand content of crude oil. The measuring tube is a plastic/rubber transparent product. The upper part of the measuring tube is cylindrical and the lower part of the measuring tube is inversely cone-shaped, a raised rim is arranged at the top of the measuring tube, and a cap is arranged at the upper part of the raised rim by means of threaded connection. The measuring tube has less possibility of being broken and can prevent a crude oil mixture from splashing during operation. The measuring tube is mounted on a crude oil water content analyzer which can automatically heat, so as to promote the reduction in viscosity of the crude oil inside the measuring tube to enable the crude oil to be easily separated from the sand during oil sample preparation, reduce the rinsing frequency and avoid the use of harmful gasoline, benzene and other solvents which are harmful for a human body.
