Enable high-precision biomass dosing in your production.
The AMI Penta Bio-venturi is the essential hardware component for the AMI Penta Bio Mixer. It enables precise irrigation and dosing of bio-fertilizers and microorganisms through advanced venturi technology, ensuring full control and optimal crop success.
Precision Dosing: Exact delivery of bio-fertilizers and beneficial microorganisms.
Smart Control: Fully integrated with AMI Penta software for diverse dosing strategies.
Easy Upgrade: Add to your existing AMI Penta to unlock Bio Mixer functionality.

Each bio-fertilizer regulates the flow from 0.25 l/m to 6 l/m (6 l/m is limited by the venturi itself and not by the flow transmitter). The water flow is reduced by 0.75 m3/h per venturi or dummy venturi. This means that if the mixer is installed with a 10 m3/h pump, the maximum water flow will be 6.25 m3/h (5 x 0.75 m3/h). The percentage of bio-dosage ratio for the total water flow can be from 0.01% to 1%.
The software in the mixer gives you several possibilities of reading facts via simple menus. Among others you can find the following:

Technical specifications
There are no specific technical specifications for the Bio-Venturi, but technical information for the AMI Penta Bio Mixer is to be found here.
One or more bio-venturi can among other things be used for:
All of these applications benefit from the precision and consistency of venturi dosing.
Each recipe can be run with bio-fertilizers. The system includes eight bio-fertilizers, which can be enabled and disabled by the user in each recipe. To work with bio-fertilizer you need to have an outlet flow sensor, analog controlled proportional solenoid valve and analog bio flow transmitter. The bio flow transmitter ensures that the dosage of each bio-fertilizer is measured and adjusted precisely, providing stable operation of the venturi. The ratio of each bio-fertilizer can via an adjusting valve be adjusted from 0,01% to 1% of the total main flow.
The bio-part (venturi) can be added to your existing AMI Penta or the function is available in a new fertilizer mixer equipped with the desired number of bio-venturi.
The AMI Penta mixer contains software for all groups, recipes and control of valves are all included in the price – meaning no extra future cost if your needs change.
This software also includes many available languages, and switching between them is very simple. This minimizes the risk of human errors in nurseries employing people of different nationalities.
The software ensures a mixer with large capacity and flexibility – and it helps you to optimize the water resources, making it a highly versatile fertilizer mixer.
Two customers with the same need of irrigation with a precise dosing of biomass – and it should be controlled automatically. As there was no fertilizer mixer on the market, which was able to do so, they contacted DGT by Senmatic. This resulted in an exciting and enriching collaboration – but what was more important was that it also ended up with the development of a bio-mixer that could meet the customer’s requirements.
