The development of flow measurement can be traced back to ancient hydraulic engineering and urban water supply systems. In the time of Julius Caesar in ancient Rome, orifice plates were used to measure the amount of drinking water used by the population. Ancient Egypt used the weir method to measure the flow of the Nile

In order to allow the rotameter to work properly and to achieve a certain measurement accuracy, the following points should be noted when installing the flowmeter.1. The rotor flowmeter must be installed vertically in the vibration-free pipeline. Fluid flow from the bottom up through the flowmeter, and the vertical degree is better than 2 °,

Before the advent of electronics, the main level detection methods were based on mechanical mechanics. The development of microelectronics has greatly facilitated the development of sensing technology and as a result, many new level detection methods and instruments have been created. Among these instruments, the radar level meter is based on the time travel method.

Radar level meters emit microwaves, which are electromagnetic waves. The reflectivity of the electromagnetic wave signal is influenced by the size of the dielectric constant of the liquid being measured. When the radar waves emitted by the radar level meter reach the surface of the liquid medium, refraction and reflection will occur. The greater the

The accuracy of the radar level meter depends on whether the selection is correct, the installation is accurate, and the installation position is appropriate, but more often than not, it also depends on the quality of the return wave. The better the quality of the echo, the more accurate the measurement, and conversely, the more

Ultrasonic level meters and radar level meters have both been developed based on the time travel method. There are many similarities between these two types of level meters, but the differences between the two are also obvious. The biggest disadvantage of ultrasonic level meters is that they are not suitable for measurements at high temperatures

Distinguished from their shape, storage tanks are divided into lying tanks, round tanks, conical tanks, vaulted tanks, and so on; distinguished from their use, storage tanks are also divided into process tanks and metering tanks. So, if the radar level meter is used to measure crude oil in the process, and the crude oil is
