A vane wheel anemometer is a flow measuring device based on a rotating vane wheel. When fluid (gas or liquid) flows past the measuring probe it sets the vane wheel in motion. The roational speed determines the flow velocity.
The Höntzsch vane wheel FA offers a specifically high measurement quality. They precisely measure even very low, bidirectional flow velocities, making them suitable for numerous applications.
当风速仪测量流体的时候，探头部分的叶轮转速和流体流速成正比。因为叶轮转速和被测介质的密度、压力和温度无关，所以可以非常精准地测量气体/液体的流速。靠近叶轮的接近开关可以无接触地测量叶轮转速，脏污颗粒也不会影响接近开关的探测能力。在同一风速仪探头上安装两个接近开关，这样就可以辨识流体的+/-正负流向。
因为叶轮的重量极其微小，所以它可以探测到毫秒级的风速和液体速度的变化，因此也能满足高精度的测量需求。
相同型号的风速仪测量同一流速时产生的频率信号也相同，因此新的风速仪探头在校准和标定之后可以直接替换旧的风速仪探头，而无需更换分体式的变送器。
Höntzsch风速仪还可以测量极微小和正负流向流动的流速。测量数据可以在手提式电脑上显示、监控和处理，从而可以快速识别和显示气耗量和泄漏量。同型号的风速仪可以同频率进行校准和标定，所以同类型的探头可以不受限制地进行互换。Höntzsch风速仪能够非常精准地测量极微小和正反流向的流速。被测数据可以通过电脑记录、监测和分析，因此用户可以快速精准地获取气耗量和泄漏量数据。
| The principle of measurement is based on the vane wheel rotating proportionally to the flow velocity of the fluid in which the sensor is inserted. The rotational speed is virtually independent of the medium’s density, pressure and temperature. The rotational speed is virtually independent of the medium's density, pressure and temperature. Vane wheel sensors deliver precise results in gases and liquids. | The vane wheel's rotational speed is detected by proximity switch, with no braking effect on the vane wheel. Contamination has no impact on impulse recognition. Installation of another proximity switch allows tracking bidirectional flow and +/- direction of flow. | Thanks to its low weight the rotational speed of the vane wheel adapts to any increase in velocity within milliseconds in gases and liquids. This ensures highly precise measurement even during quick changes in flow. |
Höntzsch风速仪拥有广泛的应用范围。无论是气体或是液体，高压力或高温的工况下，我们的风速仪都能可靠精准持续地测量流速。与许多其他测量方法相比的一个优势是，它可以用于气体成分不断变化的流体中进行精准测量。在测量去离子水和脱盐水等无法使用电磁流量计(MID)的应用中，可以选用我们的风速仪进行测量。
Höntzsch vane wheel sensors offer a wide range of applications. Whether in gaseous or liquid media, under high pressure or very high temperatures, vane wheel anemometers reliably provide measurement data.
Höntzsch风速仪的应用案例
With a Höntzsch vane wheel anemometer you can measure flow velocity and flow rate of air and gases - precisely and even at very low flow velocities.
The vane wheel respods to any change in flow within milliseconds, ensuring that even dynamic processes are captured in detail.
Even in liquids like water or non-conductive liquids our vane wheel anemometers deliver impressive measurement accuracy. They respond sensitively to changes in flow and work reliably - even in high temperatures or in chemically demanding media.
This kind of precision makes them ideal for applications where constant flow rates, exact consumption values or continuous process monitoring are important.
Thanks to high quality materials and precise bearing of the vane wheel, the sensors work reliably in high temperatures, high humidity or in dusty environments.
