Volumeter
A volumetric meter is a measuring device used to quantify the volume of liquids or gases. In agriculture, it is particularly useful for managing the volumes of water needed to prepare crop protection sprays, ensuring the safety of operators and compliance with regulations, in particular by preventing overflows when filling sprayers.
A volumetric meter is a measuring device used to quantify the volume of liquid or gas passing through it. This type of meter is commonly used in various sectors, including agriculture, industry, and water or fuel distribution systems.
How it works
A volumetric meter works by measuring the volume of fluid displaced through a measuring chamber. There are several types of positive displacement pump, each using a different method to measure volume:- Rotary piston volummeters: This type uses pistons that move in a chamber according to the flow of liquid. Each rotation corresponds to a precise volume.
- Turbine flowmeters: These measure the flow of fluid as a function of the speed of rotation of a turbine driven by the movement of the liquid.
- Nutating disc flowmeters : These comprise a disc that tilts or "nutts" in a chamber, displacing a certain quantity of liquid each time it tilts.
Applications
In agriculture, volumetric meters are often used for :- Irrigation: measuring and managing the quantity of water used to water crops.
- Distributing fertilisers and pesticides: Ensuring precise application of chemicals to crops for optimum growth.
- Reservoir management : Monitor liquid levels in reservoirs to avoid overflow or shortages.
Benefits
- Accuracy : Provides accurate measurement of liquid volume, essential for efficient resource management.
- Control : Helps automate and optimise liquid application processes, reducing costs and waste.
- Ease of use: Modern volumetric meters can be fitted with digital systems for easy reading and recording of data.
