Handheld metal detectors are designed to detect metal objects carried by people or objects. It can detect weapons, explosives, or small pieces of metal in packages, luggage, letters, fabrics, etc. carried by people. The special appearance of its sensitive surface allows easy handling. Superior to ring sensor hand probes. Ultra-high sensitivity, special application. Such as prisons, chip factories, archaeological research hospitals, etc. Handheld metal detectors are used to detect the specific location of metal carried by a person.

A turbine is placed in the center of the pipe, supported by bearings at both ends. When the fluid passes through the pipeline, it impacts the blades of the turbine flowmeter, generating a driving torque to the turbine flowmeter, which makes the turbine flowmeter rotate by overcoming the frictional moment and fluid resistance moment. In a certain flow range, for a certain fluid medium viscosity, the rotational angular velocity of the turbine flowmeter is proportional to the fluid flow velocity. Thus, the fluid flow rate can be obtained through the rotational angular velocity of the turbine flowmeter, so that the fluid flow through the pipeline can be calculated.
