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.
氣體流量計原理 熱式氣體質量流量計采用熱擴散原理，熱擴散技術是一種在苛刻條件下性能優(yōu)良、可靠性高的技術。其典型傳感元件包括兩個熱電阻（鉑RTD），一個是速度傳感器，一個是自動補償氣體溫度變化的溫度傳感器。當兩個RTD被置于介質中時，其中速度傳感器被加熱到環(huán)境溫度以上的一個恒定的溫度。 另一個溫度傳感器用于感應介質溫度。流經(jīng)速度傳感器的氣體質量流量是通過傳感元件的熱傳遞量來計算的。氣體流速增加，介質帶走的熱量增多。使傳感器溫度隨之降低。為了保持溫度的恒定，則必須增加通過傳感器的工作電流，此增加的部分電流大小與介質的流速成正比。 氣體流量計的種類 流量計的種類多種多樣，有的可以用來測量液體介質，有的可以測量氣體，還有的流量計可以用來測量蒸汽等，只有對這些流量計的工作原理及特性有所了解，在選擇時才不會手足無措。那么，測量氣體的流量計都有哪些呢？下面，我們就來簡單了解下氣體流量計的種類。 1、速度式流量計 氣體渦輪流量計 速度式流量計是以直接測量封閉管道中滿管流動速度為原理的一類流量計。工業(yè)應用中主要有： ①渦輪流量計：當流體流經(jīng)渦輪流量傳感器時，在流體推力作用下渦輪受力旋轉，其轉速與管道平均流速成正...

氣體流量計是利用液體振動原理而開發(fā)的一種新型流量計，廣泛應用在石油、化工、冶金、造紙等行業(yè)流體的計量，該流量計無可動部件，可靠性強、精度高、壽命長，可在很寬的流量范圍內(nèi)精確測量液體的瞬時流量和累計流量。其不受介質溫度、壓力、粘度及組分的影響，同時不堵、不卡、不易結垢、耐高溫、高壓，安全防爆，適用于惡劣環(huán)境。流量計分一體化顯示和遠傳顯示，并可輸出脈沖信號或電流信號與微機聯(lián)網(wǎng)。

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.
