Refractometers are fascinating instruments that play a pivotal role in various industries, from food and beverages to pharmaceuticals and gemology. These devices offer accurate measurements of a substance's refractive index, providing insights into its composition and properties. But how exactly do refractometers work? Let's delve into the science behind these instruments and uncover their mechanisms.

An anemometer is an instrument that measures static and dynamic airflow, which can be used to measure wind speed, wind force and wind direction in the air. It uses a rotating blade and is measured in feet per second or meters per second (m/s). The accuracy of the anemometer is very high, and its readings can have very good accuracy in the range of 0.1 m/s. It can also measure wind speed under low temperature, low humidity and other environmental conditions, and can quickly and accurately measure the direction of airflow. So, how much do you know about the working principle of the anemometer? Next, this article will take you to understand the working principle and application knowledge of the anemometer.

Metal detectors are widely used in examinations, security checks, archaeology and prospecting, etc., bringing more convenience to people's lives. So how do metal detectors accomplish these tasks? Next, ATO will introduce the working principle, application and structure function of the metal detector to you.

The water leak detector is a device used to detect whether there are water leakage problems in water source equipment such as pipes, water tanks, and pools. Its working principle is to judge whether there is a water leakage problem by detecting the environmental changes around the water source equipment. Next, the ATO will introduce you to the working principle of the water leak detector.

In contrast to power and energy meters, which can directly measure the loss of fiber optic cable equipment, optical time domain reflectometers (OTDR) work  indirectly. Optical Time Domain Reflectometer (OTDR) is made according to the principle of backward scattering and Fresnel inversion of light, using the backward scattered light generated when the light propagates in the optical fiber to obtain information about the attenuation, thus indirectly measuring the loss and fault location of optical fiber cables.

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.
