Senmatic updates

The capabilities are more available at this unit than the other ones.

It has a new generation decoder system that can be added in future to control the valves and get back info from field sensors as temperature, humidity, radiation, leaf temperature, ec out, drainage . We call it Siip system.

SIIP – Senmatic Intelligent Irrigation Program

• Save water and fertilizer by timely irrigation

• Increased yield and high plant quality with minimised risk of diseases

• Save labour due to the automated irrigation system

• Short return on investment

• Satisfy customer’s need for uniform products

• Standard software included for the whole set-up

• Work with real time data

• Prevent accumulation of fertilizer by EC-regulation on radiation / runoff amount and EC

• Keep all data inhouse – ease the data integration

• In particular appropriate for Soft Fruit production in gutters – but is of course also suitable for other kind of productions

Grow feed systems have to be forward facing as well as super accurate and we believe that the Senmatic is the only system than can be relied on to do this.

Fewer mixers, better results at the nursery DanRoses

When DanRoses took ownership of an older nursery on the Danish island Funen four years ago, seven fertilizer mixers from the 1980’s controlled all watering in the production, but the process was always monitored by the grower due to instability and errors. Now, fewer new mixers give better results – and peace of mind.

Since the 1980’s, seven AMI 900s and AMI 90s watered the 25,000 m2 indoor rose production at the Danish nursery DanRoses. But in later years, the grower began overseeing every single watering during daytime manually – simply because he was unsure of the old mixers’ ability to perform and whether the valves would open as intended.

“Some mornings we discovered that the planned watering at night hadn’t even started and we knew that we would not be able to catch up with watering before having to pack roses in our packing department. As a result, we would take a loss,” says Lars Olsen, who is responsible for the daily management, production, and sales at DanRoses.

Now, the seven old mixers have been replaced with three new AMI Penta from Senmatic, and the system needs no human control. “We now know that irrigation is carried out as planned with the correct dosage of fertilizer. I drive to work in the mornings with far more peace of mind and we experience less loss in our production,” says Lars Olsen, production and sales manager.

Watering reduced from 12 hours to just 2,5 hours daily
The old mixers had active watering activities for 12 hours every single day. One pump could control only one watering valve at a time and it took 40 minutes to water per valve.

With the AMI Pentas, active watering activities have been reduced to just 2,5 hours daily, irrigating through three valves simultaneously – in just 20 minutes. “We used to spend hours upon hours on watering. The old pumps were instable, we had no security when it came to fertilizer dosage and had to control the process manually. That time is now free for other tasks – and we even save fertilizer, because of the high accuracy of dosage. It’s much more effective,” says Lars.

Even greater focus on precision and large capacity with AMI Penta
Senmatic’s AMI Penta is designed to set even greater focus on the plants’ need for precision fertilizing and accurate acidity in the irrigation water and at the right time.

AMI Penta can control up to 100 groups with individual start conditions. For each group, you can choose between 20 different recipes with information about EC, pH, and the fertilizer mix. Each group can control up to 30 valves, and these can be chosen freely between the 200 valves available today in the mixer. Up to 9 valves can irrigate at the same time which gives a maximal utilization of the capacity. Irrigation time and volume can be set individually for each valve.

Air & Vacuum Air Valve AV10

Description

The AV-010 Air & Vacuum Valve discharges air at high flow rates during the filling of the system and admits air at high flow rates during drainage , pump shut-off or at water column separation.

Applications

Agricultural and landscape irrigation laterals.

Operation

The air & vacuum valve discharges air at high flow rates during the filling of the system and admits air at high flow rates during drainage, pump shut-off or at water column separation.

High velocity air will not blow the float shut. Water entry will lift the float which seals the valve.

The smooth discharge of air reduces pressure surges and other destructive phenomena.

At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.

The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused

by water column separation. Air entry is essential to efficiently drain the system.

As the system starts to fill, the valve functions according to the following stages:

  1. Entrapped air is released by the valve.
  2. Water enters the valve, lifting the float and sealing the valve.

When internal pressure falls below atmospheric pressure (negative pressure):

The float will immediately drop down, opening the air & vacuum orifice.

Air will enter the system.

Senmatic VLT new product



Product information of 5th March 2021

This information only deals with pressure control in AMI Penta and VA Penta as it requires a long explanation. Therefore, it is the only product change you get informed about this time. More information about product changes will follow the coming weeks.

If you need any clarification, you are of course always welcome to contact us.

AMI Penta and VA Penta – Pressure control
Description: 

Pressure control is a pump controlled by a B&R VLT frequency controller. The user can add up to 2 VLT controllers to the system. All the pressure control settings have been gathered in one place. Common pressure control
Pressure control enabled
No: Disabling pressure control.
Yes: Enabling pressure control. It is required to go to I/O setup and make a config by pressing the button “Make config” to load VLT frequency controller 1 into the system. Pressure pump mode
A: Only VLT 1 is enabled.
A + B: VLT 1 and 2 are enabled. This function is used to run with two pressure pumps in parallel where each pump is controlled with a VLT frequency controller. A “Make config” is required to load VLT controller 2 into the system. Pressure pump 1
Settings in this section affects only VLT 1 controller. Minimum speed
Minimum speed for pressure pump 1. The speed will always be converted to revolutions per minute (rpm) in code behind and be sent to VLT 1 analog output. The minimum speed is independent of the PI regulator which means that the pump always will maintain the minimum speed even if the PI-demand is below that minimum speed. The controller will switch to the PI-demand as soon as the actual speed demand gets over the minimum speed. Start delay
A time delay for starting pressure pump 1. Stop delay
A time delay for stopping pressure pump 1. Pressure pump 2
This section appears when the pressure pump mode is set to A + B. Settings in this section affects only VLT controller 2. Minimum speed
Minimum speed for pressure pump 2. Pressure pump 2 will only start if pump 1 gives a signal to pump 2 to start. This is dependent on the setpoint “Pump 1 speed for start pump 2”. Pump 1 speed for start pump 2
The speed of pressure pump 1 to start pressure pump 2. Start/stop delay
A time delay for starting and stopping pressure pump 2 Start hysteresis
Hysteresis for starting up the pump. Start condition
Time: the start of pressure pump 2 is only dependent on pump 1 speed for start pump 2 and the time delay.
Pressure: The start of pressure pump 2 is dependent on pump 1 speed for start pump 2, a time delay and a pressure input switch. Regulation
I time
Set the integral time for the pressure regulation. P Factor
Set the Proportional factor for the pressure regulation. [bar] Common readings
This reading section is common for both pressure pumps. Pressure
Reading the actual water pressure. Pressure demand
Reading the wanted pressure demand. P Contribution
This is the Contribution from the P regulator. [%] I Contribution
This is the Contribution from the I regulator. [%] Readings
Active
Reading the status of pump 1 and 2 Speed demand
Reading the current pump 1 and 2 speed demand. Pressure fault
Fault reset
Manual fault reset of pump 1 and 2. This can be used if the fault could not be auto reset within the pump alarm delay in the alarm settings. The reset button will only reset the latched fault if the error disappeared physically from the VLT. Alarm status
Off: Indicates that no fault exists on the VLT
On: Indicates that a fault exists on the VLT

Flexible full line solution to accelerate crop breeding at a research facility

To accelerate breeding improvements of crops such as barley, the agricultural crop breeding company Nordic Seed recently opened its brand-new indoor research facility, which has a full line instalment from Senmatic. Nordic Seeds expects to speed its early stages of the crop breeding process from 3-4 years to just 1 year.

Growing crops depend on the season; some are grown in spring and others in winter – or rather that used to be the case. With its brand-new 2,200 m2 greenhouse, Danish-based agricultural crop breeding company Nordic Seed now grows crops such as barley year-round despite its actual growing season being in winter. In just one calendar year, they expect to grow three to four generations – something which in the field would have lasted three to four years.

The objectives when breeding agricultural crops are most importantly to improve yield potential, resistance to diseases and end use quality. In other words, crop breeding research increases the number of harvested grains per ha. in the fields.

“Through crop breeding we can improve crop yield by approximately 0.5-0.75 % annually. With our new indoor research facility, where we can easily control climate, lighting, watering, and fertilizing divided in sections, we expect to accelerate the process and achieve even better results.”Jens Due JensenHead of barley breeding at Nordic Seed

Indoor growth technologies to improve outdoor crops

Being an expert in indoor greenhouse technologies, Senmatic was hired to deliver an extensive full-line technological solution for the new research facility. The delivery included all electricity installations, climate control, watering and fertilizing mixer, pipes, and ventilation.Flemming Hansen

“We are highly experienced in custom made and flexible technological horticultural solutions and were hired as full-line supplier of climate, irrigation and fertilization, pipes, and ventilation. With experience from similar research facilities, we were able to guide Nordic Seed throughout the process.”Flemming HansenProject Manager at Senmatic

Indoor growth technologies such as watering, fertilizing, climate, ventilation, and humidity can be controlled from the adjacent office space for live monitoring of growth conditions and for data analysis.

Equal growth conditions throughout the greenhouse ensure stability

Creating a greenhouse where each part of the plants’ needs can be controlled gives a homogeneous growth environment, meaning that Nordic Seed is now certain crops have identical growing conditions throughout the greenhouse – and stability is key when breeding crops, says Jens Due Jensen.

“Most grain crops will naturally seek to obtain 100 % in-breeding, making them genetic stabile. Crop breeding starts with creating diversity by controlled crosses. The breeder identifies interesting parents with high quality in terms of e.g. disease resistance and yield to carry out a controlled cross. After crossing, the lines need to be inbred for 3-4 generations before selection of superior lines can be conducted. The greenhouse speeds the process of inbreeding and allows us to work year-round and not be limited by the seasons.”Jens Due JensenHead of barley breeding at Nordic Seed

A flexible watering system

For Nordic Seed being able to sectionalize the greenhouse was important. Creating different types of crops to research and analyze the different qualities, meant that they required a flexible watering system, which could be divided into smaller sections.

To fulfil this requirement, Senmatic installed a watering valve at each table. In industrial greenhouses watering valves typically water 20 tables at a time. This means that they can control one table at a time and control and customize which nutrients, watering times and fertilizing for different crops at different tables and thereby grow a diverse selection of crops much quicker. The precise monitoring gives full flexibility.

The system makes it possible to water with different fertilizer recipes. The recipes are defined from a central computer and are delivered to the chosen table from the mixer. The mixer also controls pH-values. The new greenhouse has a total of 80 tables, two watering strands, two fertilizer tanks and two return water basins.

Senmatic as partner throughout the process

In the early stages of the extensive project, Senmatic provided planning and counselling. The building process was initiated by installing all piping and electricity.

From there the technological solutions were installed: the AMI Penta fertilizer mixer, a LCC4 for electronic climate control, sensors to control humidity, temperature and CO2, as well as gear motors and rack-and-pinion vent opening system for ventilation.
