The ultrasonic waves emitted by an ultrasonic level meter are mechanical waves that cannot be propagated in a vacuum and can only be propagated through a certain medium. Radar level meters, on the other hand, are the opposite. The microwaves emitted by radar level meters, which belong to electromagnetic waves, do not need a medium […]

The radar level meter has undergone numerous tests during the development process and the accuracy has been based on numerous experiments. However, the actual working conditions are not equal to the test working conditions. The actual working conditions may include heating devices, a limit switch in the storage tank, etc. These can cause interference to

The chemical industry is one of the more complex of the many industries. It is complex mainly because of the environment and the complexity of the production process, which may undergo one or more chemical reactions, or perhaps more than one physical reaction. Therefore, the chemical industry is very careful when choosing instruments and meters.
Rotor flowmeter used in small pipe diameter and low flow rate. Commonly used instrument caliber 40-50mm below, the smallest caliber to 1.5-4mm. suitable for measuring low flow rate small flow rate and liquid. For example, caliber 10mm below the nominal pipe diameter of the full flow of glass tube rotor flowmeter, flow rate only in

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
