MFT609 turbine flowmeter

MFT609 turbine flowmeterIt is a speed type instrument with advantages such as high accuracy, good repeatability, no zero drift, and high range ratio. Turbine flow meters have high-quality bearings and specially designed flow deflectors, which greatly reduce wear and are insensitive to peak values, and can provide reliable measurement variables even under harsh conditions. The output signal of the turbine flowmeter is pulse, which is easy to digitize. The pressure loss of the turbine flowmeter is small, and the blades (made of duplex steel) are corrosion-resistant, which can measure low viscosity and low corrosiveness liquid media.MFT609 turbine flowmeterThe application of flow measurement technology and instruments can be roughly divided into the following fields: petroleum, chemical, metallurgical, organic liquids, inorganic liquids, liquefied gases, urban gas pipelines, pharmaceuticals, food, paper and other industries.

The fluid flows through the sensor housing. Due to the angle between the blades of the impeller and the flow direction, the impulse of the fluid causes the blades to have a rotational torque. After overcoming the friction torque and fluid resistance, the blades rotate. After the torque is balanced, the speed is stable. Under certain conditions, the speed is proportional to the flow rate. Due to the magnetic conductivity of the blades, they are in the magnetic field of the signal detector (composed of permanent magnet steel and coils). The rotating blades cut the magnetic field lines and periodically change the magnetic flux of the coil, causing electrical pulse signals to be induced at both ends of the coil. This signal is amplified and shaped by an amplifier to form a continuous rectangular pulse wave with a fixed amplitude, which can be transmitted to a display instrument to display the instantaneous flow rate or total amount of the fluid. Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow rate Q of the fluid flowing through the sensor.

High precision, generally up to ± 0.5%, ± 1.0%; Good repeatability, short-term repeatability can reach 0.2% to 0.05%, and high accuracy can be achieved through regular calibration or online calibration; Output pulse frequency signal, suitable for total measurement and computer connection, no zero drift, strong anti-interference ability; The original pulse frequency range (10.0Hz~1.5kHz) has strong signal resolution; The range ratio is wide, generally 10:1, and can reach up to 15:1; Compact and lightweight structure, easy installation and maintenance, and high circulation capacity; Suitable for high-voltage measurement, the sensor body does not need to be perforated, making it easy to make into a high-voltage instrument; Strong resistance to electromagnetic interference and vibration; Low pressure loss, saving power and electricity consumption.
