FMTL Series Flange Type Liquid Turbine Flow Meter

The FMTL series liquid turbine flow meters feature high accuracy, good repeatability, simple structure, high pressure resistance, wide measurement range, compact size, lightweight, low pressure loss, long service life, simple operation, and easy maintenance. They are used for measuring the volumetric flow and cumulative volume of low-viscosity, non-corrosive, and clean liquids in closed pipelines. These flow meters are widely applicable in industries such as petroleum, chemical engineering, metallurgy, organic liquids, inorganic liquids, liquefied gas, urban gas networks, pharmaceuticals, food processing, and papermaking.

When the measured liquid flows through the sensor, the rotor is subjected to force and begins to rotate. The rotation speed of the rotor is directly proportional to the average flow velocity in the pipeline. The rotor’s movement periodically alters the magnetic reluctance of the magnetic circuit, causing the magnetic flux in the detection coil to vary periodically. This generates an induced electromotive force with the same frequency as the rotor's rotational frequency, which is then amplified, converted, and processed.

◆ Available with hygienic type, food-grade flowmeter designed for measuring both conductive and non-conductive, non-corrosive liquids.  
◆ Excellent repeatability, with short-term repeatability ranging from 0.05% to 0.2%, offering good sensitivity and stability.  
◆ Operating temperature range: -20°C to 120°C;  -20°C to 130°C optional.  
◆ Suitable for mediums with a viscosity less than 5×10⁻⁶ m²/s.  
◆ Wide measurement range: medium and large diameters up to 1:20, small diameters up to 1:10.  
◆ Optional battery powered.  
◆ Available in an insert-type design, ideal for large-diameter measurements, with continuous removal capability for easy installation and maintenance.
