Rheonik

What Rheonik does

Rheonik Messtechnik GmbH is a German manufacturer of precision Coriolis mass flow meters, founded in 1986 by Karl Küppers and headquartered in Odelzhausen, Bavaria. The company specializes in a proprietary Omega tube technology — a torsional oscillation system — that delivers mass flow measurement under extreme conditions: pressures up to 1722 bar, temperatures from -196°C to 400°C, flow rates from 0.001 kg/min to 30,000 kg/min, and accuracies up to 0.05% uncertainty. The product portfolio comprises 14 sensor models (RHM 015 through RHM 160) and 8 transmitter variants (RHE 21 through RHE 49), all custom-manufactured to customer specifications at the German facility. Differentiated software includes Assurance Factor® continuous self-diagnostics embedded in transmitters and patented signal detection algorithms in the RHE 42.

The company serves industrial customers across oil and gas, hydrogen energy, marine, automotive, chemical, petrochemical, food and beverage, paint and coating, battery, HVAC, power generation, and aerospace verticals. Revenue is generated primarily through hardware sales of sensors and transmitters, supplemented by after-sales support, calibration, and spare parts. Distribution is hybrid: direct enterprise field sales via wholly-owned subsidiaries in the United States (Houston and Auburn, CA), China (Beijing), South Korea (Seoul), India (Pune), and the UAE (Dubai), combined with a global partner network accessed through an authenticated My Rheonik portal. Pricing is not publicly disclosed and requires partner login.

Rheonik operates with 101-250 employees as an independent, owner-managed private limited company under Managing Directors Uwe Hettrich and Martin Rüther. The company was previously part of General Electric's Sensing & Inspection division from February 2008 until its 2014 management buyout to resume independent operations. The company holds an unusually broad regulatory portfolio — OIML R117 custody transfer, OIML R139 and R139-1 for hydrogen dispensers, MID certification from PTB, DNV maritime approval, ATEX/IECEx hazardous area certifications, and API MPMS Chapter 5.6 alignment — that constitutes both a competitive moat and a gatekeeper function in legal-for-trade and hydrogen fueling applications.

Core offering

Rheonik designs, manufactures, and globally distributes high-precision Coriolis mass flow sensors (14 RHM models from RHM 015 to RHM 160) and complementary SMART transmitters (RHE 21 to RHE 49) for industrial flow, density, and temperature measurement. Sensors are custom-manufactured in Germany to customer specifications, with proprietary Omega tube technology enabling measurement across flow rates from 0.001 kg/min to 30,000 kg/min, pressures up to 1722 bar, and temperatures from cryogenic to 400°C, complemented by after-sales calibration and technical support services.

Product overview

Rheonik is a precision Coriolis mass flow meter manufacturer offering a comprehensive portfolio of flow measurement solutions. The product line consists of 14 Coriolis sensor models (RHM 015 through RHM 160) covering flow rates from 0.001 kg/min to 30,000 kg/min, complemented by 8 transmitter models (RHE 21 through RHE 49) with various mounting options including field mount, panel mount, DIN rail, and integral/compact configurations. All products are powered by proprietary technologies including Omega Coriolis technology (torsional oscillation system with Omega-shaped tube design), Assurance Factor technology (real-time self-diagnostics), and specialized capabilities for high pressure (up to 1722 bar), high temperature (up to 400°C), low flow (down to 1 g/min), and fast filling applications. The sensors and transmitters are sold as integrated measurement systems, with the RHM sensors measuring mass flow and the RHE transmitters providing signal processing, display, and connectivity. An online product configurator tool enables customers to select appropriate combinations based on their specific flow, pressure, temperature, and certification requirements.
