DDM Flow Turbines – innovative and miniaturized
Flow turbines VCT series cover flow ranges from 0.05 to 350 liters per minute. Housing and rotor are made of stainless steel and can be used up to 125°C and 25 bars. The process connections are manufactured threaded or with hose connections.
D The VCT rotor geometry is further optimized and supported by a high-performance hybrid ball bearing. Those improvements resulting in a wide turndown and excellent repeatability. The turbine speed is detected with no drag to the rotor and converted into a common TTL frequency output. A miniaturized media exposed probe take accurate dynamic readings of process media temperature. VCT defaults and calibration data are stored within an integrated data memory. Combined with the smart flow computer VCA or VCA-T series a plug and play flow measuring systems is operating at high accuracy and independent from fluid viscosity.
Oval gear meter
Our oval gear meters are positive displacement meters that are suitable for measuring the flow of liquids. They are ideal for measuring oils and handling corrosive or aggressive fluids.

DDM Oval Gear Meter – Long service and small space requirement
OG series oval gear meters belong to the group of displacement meters. Flow ranges may vary between 0.01 to 500 liters. OG gear meters are dedicated to measure fluids such as water, coolant, engine and transmission oil or fuel. As liquid flows through the meter, a pair of oval shaped gears are forced to rotate by the flow of the liquid. These gears mesh together & force a finite amount of fluid through the meter. A Hall sensor detects the rotation of the gears to determine the displaced volume of liquid. The faster the flow rate, the faster the gears turn. The resulting pressure loss is very low due to the special tooth geometry. An excellent start-up behaviour allows measurements up to near standstill. Due to their design, oval gear meters measure independently of changes in viscosity or temperature of the process media. The installation is simple and space-saving, as no flow straighteners are required.
Ultrasonic flow meter
Our ultrasonic flow meters are ideal for precise inline flow measurements, especially for small quantities. They operate contact-free, ensuring low maintenance, and can measure fluids of any viscosity, density, or conductivity.

DDM Ultrasonic-Flowmeters – accurate and fully flexible
Ultrasonic flowmeters are precise flowmeters for liquids. The Atrato series of instruments can measure flow rates from 0.002 to 20 liters per minute. The flow tube has a smooth surface and contains no internals. The tube material can be chosen between stainless steel, peek and glass. For special requirements, there is the Metraflow series available. It is ideal for any application requiring a truly non-contact measurement system with a single uninterrupted, FDA approved PFA tube as the only contact material with the fluid being measured. DDM ultrasonic flowmeters generally have no internals in the flow tube. This allows measurements of high purity media as well as contaminated liquids. The velocity of the flowing medium is determined by measuring ultrasonic transit times. Using the inner diameter of the flow tube, the flow rate is calculated from this. This method is independent of pressure, temperature, conductivity and viscosity of the fluid. Ultrasonic flowmeters are characterized by low pressure drop, minimal maintenance and long service life. The measured flow rate is available via analog outputs or an integrated LCD display. Our ultrasonic flow meters are particularly suitable for applications with water.
Paddle wheel flow meter
Our Paddle wheel flow meters are ideal for accurately measuring low flow rates of low-viscosity liquids. They are an efficient solution for applications with small installation spaces and are NSF certified so that they can also be used in the food industry.
