With more than 50 years of experience in the flow measurement field and numerous innovative and customer-specific product developments, we are your qualified and competent contact for flow measuring technology and calibration. We solve even the most challenging measurement problems in close cooperation with you.
KEM offers a broad selection of measuring principles for this purpose. We develop, produce, and deliver high-quality Gear Flow Meters, Turbine Flow Meters, Helical Flow Meters, and Micro Flow Meters as well as Coriolis Mass Flow Meters worldwide. Specific accessories complement the product range. EM operates its own calibration laboratory certified according to DIN EN ISO/IEC 17025:2018. Here we intensively test each of our flowmeters before delivering it to the customer.
In the course of effective support and after-sales service, our in-house calibration expertise allows us to meet changing customer requirements for the measuring equipment they are using even years later, offering an optimum solution. KEM has modern CAD and FEM systems for design and simulation. High-precision production and great flexibility in realizing even unusual customer requirements set us apart from competitors.
As an independent manufacturer, we control all design and production processes at all times thanks to our very extensive vertical integration. We deliver quality “Made in Germany” through considerable investments in development, design, and production. KEM Küppers Elektromechanik GmbH was founded in 1965. We have been a flow-measuring technology specialist ever since. Tailor-made products and solutions for challenging measuring tasks in all industry segments set us apart.
Gear flow meters (ZHM) are positive displacement meters. Two precise gears rotate freely inside the measuring chamber. Sealed cavities are created between the gears and the housing. The measured media causes the rotation of the gears. The flowing medium is distributed evenly in the measuring chamber and causes the rotation of the gears.
The gear wheels rotate freely and are undamped in the media flow. Their rotational frequency is proportional to the flow rate and is measured by non-intrusive sensors (pickups) through the housing wall.
The ZHM MK gear flow meter (ball bearing design) are flow meters that are mainly used in lubrication and low-viscous liquids. Therefore they are used especially for fuel consumption measurement and the dosing of low viscous media. Only high-grade steels that even withstand corrosive liquids are used in the production of gear flow meters. Combined with the use of high-quality precision ball bearings, the ZHM MK guarantees optimum measurement accuracy and long service life under even the toughest application conditions. The ball bearing facilitates a very low starting torque of the measuring element. This is the way even the lowest flow rates can be accurately measured.
Short response times, very dynamic performance and high measurement accuracy ensure accurate regulation and control of flow rates in demanding applications. For applications in hazardous areas, we offer intrinsically safe sensors and amplifiers with Ex protection in accordance with ATEX, IECEx, CSA, and other standards. Additional certifications such as EAC (TR-CU) are available.
These meters are suitable for accurate measurement of different liquids with viscosities of approximately 1 to 25,000 mm²/s.
