The so-called scales «Weight slabs» designed by LABORATORY OF ENGINEERING SYSTEMS today are the most reliable and fast method for determining humidity content.
The scales are intended for continuous control of plant weight, drainage water parameters and also plant’s vital activity parameters in industrial greenhouses. Installation is made of acid-proof and durable materials (stainless steel and PVC). The measuring electronics are installed in waterproof enclosures based on ARM controllers.
The parameters measured by these scales can be used to analyze efficiency of irrigation and microclimate system, to adjust the irrigation strategy and also to estimate the effectiveness of the staff activity.
These scales automatically allow continuous monitoring of:
- slab weight;
- water saturation of the substrate;
- electrical conductivity (EC) and temperature at the collection point of drainage;
- drainage volume;
- drainage percent after watering and during a day;
- irrigation solutions’ volume and drainage from the plant.
System monitoring be able to monitor the parameters of the plants’ vital activities: monitor the parameters of the plants’ vital activities: - sap flow in stalk and petiole leaf;
- stem diameter;
- fetus’ diameter;
- leaf temperature;
- acidity of drainage;
- soil humidity;
- soil temperature;
- fetal weight;
- temperature measurement by means an infrared surface temperature sensor.
These scales can work as a part of the irrigation system and separately from it. When it is operated separately from other equipment, watering control is carried out using a flow meter installed at the outlet of the irrigation valve.
All measured parameters are transferred to the main computer where they are integrated with the data received from the irrigation unit using special software.
The program of the main computer allows in a graphic way to control the whole process of irrigation in parallel with the dynamics of the measured parameters. The program on the main computer allows you to archive additionally all data for an unlimited time and print reports in a graphical and tabular form.
