1. Is the water meter charged hourly or based on the amount of water used for irrigation? The water meter is usually charged based on the amount of water used, but there are also some areas or equipment that use hourly charges, which need to be determined based on local policies or meter design. 1. The water fee model is more common: In most modern agricultural irrigation scenarios, card swiping electricity meters will be charged based on actual water usage (cubic meters/ton). This type of electricity meter has a built-in flow sensor that directly measures the water flow rate. After the user deposits a fee, the fee will be automatically deducted when using the water, and the deducted amount is proportional to the water consumption. 2. The hourly billing model exists but is rare: a few old equipment or specific areas may charge based on the running time (hours) of the water pump. In this case, the electricity bill is directly linked to the power and running time of the water pump. For example, a 1.5-kilowatt water pump that works for one hour is charged at the unit price of electricity, which is suitable for old-fashioned equipment without flow meters, but is susceptible to the impact of water pressure fluctuations on fairness. How to determine the type of electricity meter you have: - Look at the meter nameplate or instruction manual, the words "flow meter" or "water meter" are mostly used for water volume charging. -Observing the logic of card swiping charges: If the water usage is low but the charges are low, it may be due to water usage billing; If there is a fixed deduction for the same duration, it may be time billing. -Consult the local water management department or village committee to confirm the local unifi
2. What equipment is required for the head of the drip irrigation system?
The head of the drip irrigation system generally needs to be equipped with the following equipment: power machine and water pump. Power machine is the core equipment that drives the operation of the water pump, mainly including electric motor, diesel engine, tractor and other power output equipment.
. The types of water pumps include submersible pumps, centrifugal pumps, etc., used for simulating the transportation of water from the water source to the system. If the natural head of the water source (such as a high-level water tank) can meet the flow and pressure requirements of the drip irrigation system, water pumps and power equipment can be eliminated. The fertilization (pesticide) system is used to add fertilizers or pesticides to irrigation water, and the main equipment includes: fertilization (pesticide) tank: a container for storing fertilizers or pesticides. Venturi fertilizer applicator: It inhales fertilizers or pesticides through the Venturi effect and mixes them with irrigation water. Fertilizer pump: Inject fertilizers or pesticides through mechanical pumping. Fertilizer applicator: an automated device that can accurately control the amount and timing of fertilizer application. The filtration system is used to remove impurities from irrigation water
