Flow meter for agriculture / agribusiness

for the delivery of liquid media as required

In modern agriculture, fertilizers and plant protection products are used to secure yields and maintain soil quality. Overdosing these products leads to unnecessary costs and causes negative impacts on soils, surface water, and groundwater.
However, with precise dosing and efficient resource use, the environment can be protected while ensuring economic operations.
The accurate application of liquid media, tailored to the specific requirements of the soil, is one of the main challenges in agriculture.
DDM flow meters offer an optimal solution, helping to efficiently use resources and minimize environmental impacts.
They are robust, resistant to media, and measure liquid quantities in real time. This enables exact dosing and seamless documentation of the actual amounts applied.
Below, we present various flow meters that are ideal for precise dosing in agriculture:

Pelton wheel Flow Meters: Ideal for Water-like Media

Pelton wheel flow meters are compact and robust devices with an excellent price-performance ratio. Thanks to their sapphire bearings, they offer long-term stability and minimal wear, resulting in a long service life and low maintenance costs.
They are particularly suited for water-like liquids, such as liquid fertilizers or water-based plant protection products.
These meters provide reliable real-time measurements, allowing users to continuously monitor and adjust the application rates. Due to their robust construction, paddlewheel flow meters can also be used in harsh environments.

Oval Gear Flow Meters: Precise Measurement Independent of Viscosity

Oval gear meters are volumetric meters that are independent of the medium’s viscosity.
This makes them ideal for highly viscous liquids, such as thick fertilizers or concentrated plant protection solutions.
Another advantage is the availability of high-pressure variants, suitable for applications with pressures up to 400 or 700 bar.
Oval gear meters offer high measurement accuracy and are particularly resistant to wear. They are perfectly suited for demanding environments where highly viscous media need to be dosed precisely.

Ultrasonic Flow Meters: Perfect for Small Flow Rates

The ultrasonic flow meters of the Atrato series are specially designed for applications with very small flow rates starting at 2 ml/min.
These devices are optimal for dosing fertilizer concentrate, as they enable extremely accurate measurements, even at minimal flow rates.
A special feature of these flow meters is the integrated display, which shows both the current flow rate and the cumulative amount of the medium applied. This allows for continuous monitoring and documentation of the application rates, helping to avoid overdosing and optimize resource use.
