DGT by Senmatic AMI Penta Bio-Venturi

The Bio-Venturi is a part which can be added to an existing AMI Penta Fertiliser Mixer, or purchased as part of a new fertiliser mixer setup, in order to add biomass (bio-fertilizer and beneficials / microorganisms) as part of your fertiliser regime.

By mixing biomass, the addition can irrigate the culture medium at a very precise dosage. AMI Penta controls the irrigation flow so that the software in the mixer allows for different dosing strategies. Exact dosing provides you with control and thus success with your production.

In order to work with bio-fertilizer your system will need to have an outlet flow sensor, analogue controlled proportional solenoid valve, and analogue flow transmitter. The ratio of each bio-fertilizer can be adjusted via an adjusting valve from 0.01% to 1% of the total main flow. Each fertiliser recipe has the opportunity to include bio-fertilizers. The system includes eight bio-fertilizers, which can be enabled and disabled by the user in each recipe.

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 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 optimise water resources.

AMI Penta is extremely flexible and the range of options available can allow you to optimise your system. These options will depend on your crop, environment, and fertigation requirements. To ensure you get the right setup for your production system we would recommend speaking to our in-house experts.



  • Controlled environment agriculture (CEA) facilities
  • Commercial grow operations
  • Greenhouses and nurseries
  • Vertical farming
  • Indoor farming



  • Precise dosing of biomass (bio-fertilizers and beneficials /microorganisms) based on flow of water from the mixer to your cultures
  • Dosing of biomass can be done independently on EC and pH
  • Savings on working hours as irrigation of biomass is done automatically by the mixer
  • Savings on use of biomass – you only use the needed amount and don’t have any waste
  • Software for all groups, recipes and opening of valves is included in the price – no extra future cost if your needs change
  • User-friendly software – you can also make your own setups
  • Up to 8 Bio-venturi can either be added to your existing AMI Penta Mixer – or a new AMI Penta Mixer can be equipped with the needed number of Bio-venturi



The software in the mixer gives you several possibilities of reading facts via simple menus. Among others you can find the following:

Bio-fertilizing can be included in every fertiliser recipe, and the screen shows you:

  • A function selector to enable or disable bio-fertilizing in a recipe
  • A column showing if the single fertilizer is disabled or enabled
  • A ratio-column informing of the bio-dosing ratio of the total current outlet flow for each fertilizer

An overview of the bio-fertilizer activity showing you:

  • Reading of the current bio-flow demand for each bio-fertilizer calculated out of the current outlet flow in l/m
  • Reading of the direct bio-flow from the flow transmitter in l/m
  • Reading of the averaged bio-flow in l/m
  • Reading of the current deviation of the bio-flow measuring compared to the flow demand

Next steps:

There are a range of factors to consider before building your AMI Penta fertigation/irrigation solution. In advance of speaking to our in-house experts, getting a clear idea of some of the requirements of your operation will help to identify the right solution for you.

  • How many cubic litres of liquid per hour will the system need to manage?

This will define the pump size.

  • How many types/lines of fertiliser or control solution are desired?

This will determine the number of venturis needed.

  • Do you wish to control pH?

This will determine sensors needed.

  • How many irrigation valves are needed?
  • Do you aim to develop a recirculating system and reuse water/fertiliser mix?

This will determine if additional equipment such as a return tank are needed

Don’t worry if you do not have the answers to everything just yet – we can help!
