Pulse-output water meter
Turbine or Woltmann type, installed on the pipe: it sends a pulse to the pump for every set volume of water.

Fertigation systems
Volumetric dosing
The pulse-output water meter on the irrigation water pipe controls the fertiliser and acid dosing pumps, which dose in proportion to the volume of water.
- Dosing proportional to volume
- Fertiliser and acid
- On tank, panel or skid

Components
Basic components
Dosing pump
Solenoid dosing pump with adjustable flow rate, controlled by the controller or by the pulses from the water meter.
Dosing pumps →
Tank
In PE, with suction lance fitted with foot filter and level probe, and safety bund.
Tanks →
Injection lance
It introduces the product into the centre of the pipe, improving mixing; it can be withdrawn with the pipe under pressure.
Lances →
Operation
Operation
Proportional to volume
Each pulse from the water meter corresponds to a volume of water: the pumps dose a proportional quantity.
Two products
One pump for the fertiliser and one for the acid, with independent settings.
No probes
Suitable when the quality of the irrigation water is constant.
Alarms
Level probes in the tanks: they signal that the product is running low.

Installations
Installation examples
Systems are supplied pre-assembled and tested, in the form best suited to the plant room: on a panel, in a cabinet or on a skid (with cover, in a box or on a frame), also tailor-made. Some examples.
On a panel
Controller, pumps, probe holder and accessories mounted and wired on a wall panel.
In a cabinet
System panel and chemical tanks housed in a single cabinet.
Wall cabinet
Pipework, pumps and electrical panel in a wall cabinet with door.
Skid with cover
Skid with raised stainless steel frame and protective PMMA cover.
Skid in a box
Skid enclosed in a box with door, with the chemical tanks at the base.
Skid on a frame
Skid on a frame with doors, pre-assembled and ready for connection.
On the tank
Dosing pump mounted directly on the tank: the most compact solution.
In the plant room
Wall installation in the plant room, with the chemical tanks on the floor.
Pumps, controllers or components supplied by the customer can also be fitted, with custom dimensions, back panel and electrical panel. Dosing stations and skids →
Which one to choose
From the simplest to the most complete solution
For pH control the basic solution is the dosing station; when dosing has to be controlled by the measured value, measuring controllers are used.
Dosing station
The simplest solution: the pump doses at a constant rate or in proportion to the volume of water measured by the pulse-output water meter.
Details →
LDspH – pH
pH measurement and dosing of acid or alkali up to the set value.
Details →
LD Dual Parameter
Simultaneous management of two parameters, for example pH and chlorine, with a single controller.
Details → Centurio PRO
Management of up to 10 parameters and of all the pumps in the installation, with touch screen and remote control as standard.
