Product Description
Turbine flowmeters are the main variety of impeller-type flowmeters and consist of a sensor and a converter-icator. The sensor employs a multi-bladed rotor to sense the average velocity of the fluid, thus deducing the flow rate or total volume. Turbine flowmeters velocity-type instruments with the advantages of high accuracy, good repeatability, simple structure, few moving parts, high pressure resistance, wide range of measurement, small size, light weight low pressure loss, and easy maintenance. They are used to measure the volume flow and total volume of liquids in closed pipelines. They first convert the flow velocity into the rotational speed of turbine and then convert the rotational speed into an electric signal that is proportional to the flow rate. Its output signal is frequency, which is easy to digitize. The induction coil and are fixed together on the housing. When the ferromagnetic turbine blades pass by the magnet, the magnetic resistance of the magnetic circuit changes, thus generating a frequency signal. At the same, the pulse frequency is converted into a frequency-voltage conversion to indicate the instantaneous flow. The rotational speed of the impeller is directly proportional to the flow rate, and the output the turbine flowmeter is a frequency-modulated signal, which not only improves the anti-interference of the detection circuit but also simplifies the flow detection system. It is widely to measure the volume of liquids in closed pipelines that are less corrosive and do not contain fibers, particles, and other impurities. It can also be used for quantitative control, overquantity alarm, etc., and is an ideal instrument for flow metering and energy saving. It has been widely used in petroleum, chemical industry, scientific research, national defense,rology, and other fields.
