Industry Information
Next-generation liquid turbine flowmeter with easy installation and maintenance
2012-3-5 10:52:43

具有精度高,重复性好,寿命长操作简单等特点。 FM110 series liquid turbine flowmeter has the characteristics of high accuracy, good repeatability, long life and simple operation. It can be widely used in petroleum, chemical, metallurgy, papermaking and other industries to measure the instantaneous flow volume and total volume of liquids. It is suitable for measuring liquids in closed pipelines that do not corrode with stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3, and cemented carbide, and have no impurities such as fibers and particles.
If it is matched with a display instrument with special functions, it can also perform quantitative control and over-alarm.
The sensor is suitable for mediums with a viscosity less than 5 × 10-6m2 / s at the working temperature. For liquids with a viscosity greater than 5 × 10-6m2 / s, the sensor must be calibrated with a solid solution before use.

Features:
★ High precision, long life, simple operation and maintenance,
★ Used in petroleum, chemical, metallurgy, water supply, papermaking and other industries.
★ Can output a variety of signals, such as pulse, 4 ~ 20mA two-wire analog output,
★ Optional battery-powered on-site display, 24V power-on-site display ★ Threaded connection / flange connection ★ Small pressure loss, impeller has anti-corrosion function.
具有较高的抗电磁干扰和抗震动能力,性能可靠工作寿命长。 ★ Liquid turbine flowmeter has high anti-electromagnetic interference and anti-vibration ability, reliable performance and long working life.
★ Adopting advanced ultra-low power single-chip microcomputer technology, the machine has strong functions, low power consumption and superior performance. Intelligent flow display with non-linear accuracy compensation. The accuracy of the correction formula is better than ± 0.02%.
★ The meter coefficient can be set online by keys and can be displayed on the LCD screen. The LCD screen is intuitive and clear, and has high reliability.
★ Use EEPROM to protect the accumulated flow and meter coefficient from power failure.
