Höntzsch – measuring technology since 1966 For Höntzsch the measuring of flow isn’t only a profession but also passion. We develop measuring solutions for all requirements in every environment. Our measuring instruments are applicable at high pressures up to 50 bar. They deliver precise measuring results even with smallest flow measuring velocities and lowest volume flows. In sample gases such as ammonia, butadiene, hydrogen, LPG, natural gas, propane and many other media Höntzsch measuring instruments deliver exact values. Our flow sensors are applied even under toughest circumstances such as strong pollution or dust pollution. Höntzsch is a specialist for the development, production and distribution of innovative products for the measuring of flow. Our high quality standard and measuring precision are supported by high-quality materials such as aluminium, stainless steel, Hastelloy, titanium, tantalum, guaranteeing longevity even under toughest operating conditions. Höntzsch measuring instruments are known for their reliable measuring results especially in extreme applications. Their unique strength lies in hazardous areas, in aggressive media, gases with temperatures up to 550° C, high flow velocities up to 200 m/s or in pipe flows with changing gas compositions or flow direction.
