Metal tube variable area flow meter is a traditional variable cross-section flow meter, which has many advantages such as simple structure, reliable operation, small and stable pressure loss, and can measure low flow rate media. It is widely used in measuring high temperature, high pressure, and corrosive fluids. medium. As determined by the measurement principle of the metal tube flow meter, it generally needs to be installed vertically. However, in some specific industrial applications, it is necessary to use a horizontally installed rotameter. Although the measurement principle is the same as the classic vertical rotameter, It is a rotameter with a special structure that can be installed in horizontal pipelines.

The dead zone is the region of time where the tester is temporarily blinded by a large amount of reflected light until it recovers and can read light again. Since the optical time domain reflectometer (OTDR) works by calculating the length of the cable and the point of failure based on time, a large number of reflections will cause the tester to take more time to recover, which creates a dead zone. The limitations of dead zones make optical time domain reflectometers (OTDRs) largely incapable of troubleshooting.

An electromagnetic flow meter (EMF for short) is an instrument that uses the principle of electromagnetic induction to measure the flow of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field.

An oscilloscope is a laboratory instrument commonly used to display and analyze the waveform of electronic signals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time. An excellent oscilloscope for testing and analysis, an oscilloscope is a must-have for many industries and applications such as RF design, general electronic circuit design, electronics manufacturing, service, repair, and more.
