Turbine flowmeters – highly accurate measurement over a wide measuring range

TrigasDM Turbine Flowmeters are the ideal solution for liquid measurement applications requiring high accuracy, very fast response times and compact design. They provide a perfect reliability in continuous operation, also at constant flow changes and fluctuating operating temperatures. They are not sensitive to vibration, shock and humidity, special versions available in IP67 including also pickoffs and electronic amplifier.

TrigasDM Turbine flowmeter have a wide range of applications. These include f.e. monitoring of flow rates of fuels and coolants in motors and engine development, dosing exact quantities in food and pharmaceutical industry, monitoring and measurement of ultrapure water in research and development, quantity measurement for consumption.

Mobile measurement technology in test vehicles

The special lightweight version of the DM series was developed for applications with small spaces. Due to the extremely compact design of the housing, the flowmeter installed between two hose ends hardly takes up any space. The stainless-steel DM turbine is significantly lighter than a comparable flowmeter and therefore the first choice for mobile measurement technology, whether in the engine compartment or in the hand luggage on the next flight to the test drive.

Typical applications are measurements of flow rates of fuel, cooling water, engine oil, coolant (for example, R134a)…

Together with the compact and powerful linearization Electronics Lysis measurement turbines can be installed up to 15 meters from the data-logger. Whether truck, car or motorcycle, the DM – Series provides real-time temperature compensation, high accuracy, very fast response, compact design and high reliability at an attractive price-performance ratio.
