Turbine Flow Meter

Turbine flow meters use the mechanical energy of the liquid to rotate a rotor within the flow stream. The rotational speed is directly proportional to the velocity of the fluid traveling through the meter. These meters are used in multiple industries to reliably measure liquids and gases. Turbine flow meter series is used to measure continuous and discontinuous flow rates. They are mainly used for lubrication and non-lubrication media. They are particularly suitable for low and medium viscosity liquids, such as water, emulsions, glycol mixtures and light oils.

• High precision, typically ±0.5% or ±1.0%;
• Good repeatability, short-term repeatability can reach 0.2% to 0.05%, and extremely high precision can be achieved with frequent or online calibration;
• Output pulse frequency signal, suitable for total quantity measurement and computer connection, no zero drift, strong anti-interference ability;
• Original pulse frequency range (10.0Hz to 1.5kHz), strong signal resolution;
• Wide range ratio, typically 10:1, up to 15:1;
• Compact and lightweight structure, convenient installation and maintenance, large flow capacity;
• Suitable for high-pressure measurement, no holes are needed on the sensor body, easy to manufacture high-pressure instruments;
• Improved Flow Range. Features an increased linear flow range with less sensitivity to fluid temperature or viscosity effect on the output.
• Enhanced Performance. Built with a helical rotor design, resulting in exceptional speed-of-response with reduced pressure drop.
• Comprehensive Pickoff Selection. Eliminates rotor drag while magnetic pickoffs provide for high temperature and remote powerless installations.

The turbine flow meter relies on the force of the fluid to drive the turbine's rotation. When fluid enters the flow meter, it first passes through a guide vane, which acts like a traffic officer, organizing the fluid to impact the turbine at a stable flow rate and direction. Under the impact of the fluid, the turbine begins to rotate rapidly, and its rotational speed is directly proportional to the fluid's flow rate. This is similar to using a fan to power a windmill; the stronger the wind, the faster the windmill spins.

To accurately measure the turbine's rotational speed, the turbine flow meter uses a magnetoelectric sensor. A magnetic conductor is installed on the rotating part of the turbine. As the turbine rotates, the magnetic conductor rotates as well, periodically changing the magnetic resistance of the magnetic circuit. According to the principle of electromagnetic induction, this change in magnetic resistance induces corresponding electrical pulse signals in the coil. By collecting, analyzing, and processing the frequency of these electrical pulse signals, the corresponding fluid flow rate can be calculated and displayed.

Aviation & Aerospace

The aviation/aerospace industry has the most demanding operating conditions. Sensors must be able to adapt to the environment, continue to function properly in harsh conditions, be able to fit into extremely narrow spaces, and their electronic components must be able to compensate for various changing conditions, thereby providing precise and repeatable results. When verifying the performance of equipment used in commercial and military aircraft, no compromises are allowed.
