Aquametro气体流量计VZF II 25 FL 180/25中国区代理
Since 1928, Aquametro Oil & Marine has been among the leading manufacturers and suppliers of measurement, optimization and monitoring solutions for all kinds of fluids on ships, vehicles and industrial applications.
Innovation has always been of great importance to us. It not only involves the development of new products and technologies, but also the design of new or improved production technologies and production methods. Innovation means that we are always a step ahead of the rest. To achieve this we draw back on years of experience and tradition, which always opens new doors for us
Our range consists of more than 100 different oil fuel meters and management systems which have been developed specially for ships, transport vehicles and other heavy machinery in the shipping and industrial sector. We are also considered experts in viscosity measurement and control as well as in measurement, monitoring and management systems for fuel performance and fuel switching units (HFO to MDO and vice versa). For the industrial sector we offer flowmeters and dosing units for special fluids.
气体流量计原理 热式气体质量流量计采用热扩散原理，热扩散技术是一种在苛刻条件下性能优良、可靠性高的技术。其典型传感元件包括两个热电阻（铂RTD），一个是速度传感器，一个是自动补偿气体温度变化的温度传感器。当两个RTD被置于介质中时，其中速度传感器被加热到环境温度以上的一个恒定的温度。 另一个温度传感器用于感应介质温度。流经速度传感器的气体质量流量是通过传感元件的热传递量来计算的。气体流速增加，介质带走的热量增多。使传感器温度随之降低。为了保持温度的恒定，则必须增加通过传感器的工作电流，此增加的部分电流大小与介质的流速成正比。 气体流量计的种类 流量计的种类多种多样，有的可以用来测量液体介质，有的可以测量气体，还有的流量计可以用来测量蒸汽等，只有对这些流量计的工作原理及特性有所了解，在选择时才不会手足无措。那么，测量气体的流量计都有哪些呢？下面，我们就来简单了解下气体流量计的种类。 1、速度式流量计 气体涡轮流量计 速度式流量计是以直接测量封闭管道中满管流动速度为原理的一类流量计。工业应用中主要有： ①涡轮流量计：当流体流经涡轮流量传感器时，在流体推力作用下涡轮受力旋转，其转速与管道平均流速成正...

气体流量计是利用液体振动原理而开发的一种新型流量计，广泛应用在石油、化工、冶金、造纸等行业流体的计量，该流量计无可动部件，可靠性强、精度高、寿命长，可在很宽的流量范围内精确测量液体的瞬时流量和累计流量。其不受介质温度、压力、粘度及组分的影响，同时不堵、不卡、不易结垢、耐高温、高压，安全防爆，适用于恶劣环境。流量计分一体化显示和远传显示，并可输出脉冲信号或电流信号与微机联网。

The CONTOIL® DFM-BC is the suitable computer and display, which covers all direct and differential applications in fuel metering. It can be used for all available flowmeter sizes.
 Aquametro Oil & Marine operates from its headquarters in Therwil/Switzerland and Rostock/Germany as well as from Singapore for the Asian market. With further subsidiaries in South Korea and China and representation offices in India and Japan plus a global service network and numerous sales partners around the world we can offer you seamless, professional and solution-driven support.
We have the technical capabilities and expertise to calibrate all flowmeters and heat meters, including temperature sensors from our own product range and from other manufacturers. This method includes static and dynamic measurements systems. The Swiss Accreditation Service (SAS) has also certified us as SCS 0077 (Swiss Calibration Service). The basis for all our activities is our ISO 9001 quality certificate. We have automatic calibration equipment for flowmeters ranging from 4 mm (DN 4) to 50 mm (DN 50)

Newly calibrated measuring instruments with regular re-calibration strengthen the relationship of trust with the customer and guarantee accurate cost accounting and consumption estimates. All these factors contribute to reducing costs. The recalibration keeps the operating costs of the measuring instruments low and extend the service life of the instruments. A calibration certificate in accordance with EN 17025 certifies national recognition, creates confidence in the internationally recognized test mark and certifies the quality of your measuring instruments and your technical skills. Do you have special requirements or measuring points that you would like to have tested or inspected? Then our expertise and know-how are at your disposal. Take advantage of this offer and request information brochures about our calibration centre or contact us directly.
