Two data, two different questions
The EC And pH doesn't say the same thing about the greenhouse water system. The EC the measurement data related to electrical conductivity, pH related to spy activity. The two together only show the status of the named sample or measuring point. A favourable value may not be inferred from all ingredients or the entire plant environment. Therefore, the project is important for the investor to measure, to work with the equipment and to interpret cultivation. Before acquiring the sensors, be clear which decision and which system status you intend to use the data for.
The sampling site must have a name
The measurement of spring water, prepared irrigation water and recurrent water may be a different issue. If the data sheet contains only one number without the status designation, it may be easy to compare it. Therefore, the measuring points should be identified in the technological drawing. M Hoogendoorn sensor side and FAO the production guide provides a professional background for linking data and use. However, the determination of the specific target value is the professional task of the chosen plant and cultivation technology. The setting in a general article would not be an appropriate basis for an unknown source of water and plant stock.
Check the quality of the measured data
The state of the sensor, the environment of use and the order of control affect the extent to which the data can be used for decision-making. The maintenance tasks shall be designed according to the equipment instructions. The operator knows what is required for comparison or professional checks and how to indicate the uncertainty in the log. A sudden deviation may be a real system condition, but a measurement problem may occur. The two should not be treated automatically with the same intervention. The response to the measurement error and missing data in the regulation should therefore be coordinated separately with the system supplier.
The regulatory consequences should be understandable.
There may be several steps between the information displayed on the display and the intervention associated with it. The setting, the operator decision and the operation of the dosing system are given a separate role. The technical take-over shall show the state in which the procedure is to start and the results of the feedback. The operator must also understand which data is used for checking and which is to initiate a regulatory operation. The same abbreviation may refer to different system points on multiple displays. The rediscussion of nominations and names is therefore a simple but important part of the fact that conditions do not mix during daily work.
Trends can only be interpreted from the same conditions
A graph showing several days or zones may be useful if the test point, stock and configuration history are also known. A converted water source or modified production programme means a new comparison situation. The date of the change should therefore also be indicated in the chart. The missing or unverified data should not remain displayed in the same way as reliable measurement. This is how the assessment specialist can see which conclusion the data set is suitable for. The aim is to understand your own system, not to present a lot of measuring numbers or a constantly changing display.
Questions to reconcile the project
- Exactly which water state and system point is the EC Or pH data?
- What control and maintenance system does the sensor have?
- What is the reaction to uncertain or missing measurement?
Professional background
The related international system solutions are provided by these primary manufacturers and execution sites. The decision aspects of the project shall be interpreted independently by the article; the specific size and content of the undertaking shall be clarified on the basis of the investment data.
