The tipping bucket flowmeter (also known as the tipping bucket flowmeter) is a flow measurement device based on the "volumetric measurement principle". Its core is to achieve cumulative measurement of the volume of fluids (mainly liquids, partially adapted to low viscosity gases) through "tipping bucket alternating flipping". It has the advantages of simple structure, low cost, stable measurement, and no need for complex maintenance. It is widely used in scenarios with "low flow rate, small flow rate, and moderate measurement accuracy requirements", especially suitable for fluids that do not contain a large amount of impurities and have low viscosity. The following are its main application areas and specific scenarios:
1、 In the field of water resources and water treatment, the core is used for "small flow water metering"
The water resources field is the most typical application scenario of tipping bucket flow meters, especially suitable for "decentralized, low flow" water monitoring, to solve the problems of high cost and insufficient accuracy of traditional flow meters (such as electromagnetic flow meters) in low flow scenarios:
Agricultural Irrigation and Water Conservation Monitoring
Application scenarios: Single plot flow measurement for drip irrigation and sprinkler irrigation systems in farmland, precise irrigation control for orchards and greenhouses.
Core value: The tipping bucket flowmeter can be directly installed on the irrigation branch pipe to measure the water consumption of a single plot in real time (such as small flow rates of 0.1-5m ³ per hour), helping farmers achieve "charging according to water consumption" and "precise control of water fertilization", avoiding water resource waste; Some devices can also be equipped with wireless modules to upload data to the agricultural irrigation cloud platform for remote monitoring.
Measurement of Rainwater Recycling and Reclaimed Water Utilization
Application scenarios: Flow metering for rainwater collection systems in building communities and factories (collecting rainwater from roofs and roads), as well as for reclaimed water (such as after treating bathing wastewater) reuse systems.
Core value: Rainwater/reclaimed water flow is usually small (daily recycling volume 1-10m ³), and the tipping bucket flowmeter can achieve flow accumulation at low cost, helping users to calculate the "total amount of water saved" (such as recycling 50m ³ of reclaimed water per month in the community, equivalent to saving tap water costs), while meeting the measurement requirements of the environmental protection department for "water resource recycling".
Groundwater monitoring and small-scale water supply stations
Application scenarios: Measurement of water output from decentralized wells in rural areas (for 10-50 households), monitoring of flood discharge from small reservoirs/mountain ponds.
Core value: groundwater exploitation needs to strictly control the flow (to avoid land subsidence caused by overexploitation). The tipping bucket flowmeter can operate stably for a long time (resistant to the low corrosivity of well water) without frequent maintenance. It helps the water department to count the daily average mining output of a single well and achieve groundwater control; Small water supply stations use them to measure the amount of water supplied to villages, supporting the implementation of "tiered water pricing".
2、 In the field of environmental protection and ecological monitoring: adapting to "low concentration, low flow fluid metering"
In the field of environmental protection, tipping bucket flow meters are mainly used in scenarios such as "pollutant emission monitoring" and "ecological hydrological monitoring", especially suitable for measuring "low flow, low impurity" fluids:
Measurement of wastewater discharge from small-scale pollution sources
Application scenarios: Wastewater discharge outlets for small factories in towns and villages (such as food processing and small-scale chemical industries), and wastewater discharge measurement for catering enterprises.
Core value: The wastewater discharge from these types of pollution sources is usually small (1-50m ³ per day), and the suspended solids content in the water is low (after pretreatment). The tipping bucket flowmeter can be directly installed at the end of the discharge pipeline to cumulatively measure the daily/monthly discharge, providing data basis for the environmental protection department to collect "discharge fees" and "monitor standard emissions"; Compared to electromagnetic flowmeters, their procurement cost is only 1/3-1/5, making them more suitable for small businesses.
Ecological hydrology and wetland monitoring
Application scenarios: Stream flow monitoring in nature reserves, wetland replenishment/withdrawal flow measurement, and surface runoff monitoring in forest watersheds.
Core values: Ecological monitoring requires long-term, in-situ measurement (such as monitoring seasonal flow changes in streams and analyzing ecological water demand), the structure of the tipping bucket flowmeter is sturdy (can be installed outdoors, can withstand temperature changes from -20 ℃ to 60 ℃), and does not require external power supply (some are equipped with solar power supply), enabling unmanned monitoring; For example, when replenishing water in wetlands, use it to measure the amount of water replenished to ensure the stability of the wetland ecological water level.
Measurement of Atmospheric Precipitation and Leachate
Application scenarios: Rainfall auxiliary measurement at meteorological stations (combined with a tipping bucket rain gauge, essentially a special form of tipping bucket flowmeter), and flow measurement of leachate (sewage generated from garbage decomposition) in landfills.
Core value: The tipping bucket rain gauge is a standard equipment in the field of meteorology, which converts rainfall by the number of flips of the tipping bucket (such as 0.1mm rainfall per flip); The leachate flow rate of the landfill site is small (0.5-5m ³ per day in a single area), and corrosion prevention is required (the leachate contains a small amount of organic acid). The dedicated anti-corrosion tipping bucket flowmeter can achieve long-term measurement and avoid soil pollution caused by the indiscriminate discharge of leachate.
3、 Industrial and civilian fields: focus on "low viscosity, low flow fluid measurement"
In industrial and civilian scenarios, tipping bucket flow meters are mainly used for "auxiliary production measurement" and "civilian small flow fluid statistics", suitable for fluids with low precision requirements (± 2% - ± 5%) and no high viscosity/high impurities:
Industrial auxiliary fluid measurement
Application scenarios: Water replenishment measurement for factory cooling systems (such as water replenishment for machine tool cooling water tanks, flow rate 0.05-1m ³/h), and water supply flow measurement for small boilers (low-pressure, low flow scenarios).
Core value: The measurement of this type of auxiliary fluid does not require high precision (only counting whether it meets the standard for water replenishment), and the tipping bucket flowmeter can be directly installed in the water replenishment pipeline, with low cost and low risk of failure; For example, if the cooling water tank of the machine tool is not replenished enough, it will cause the equipment to overheat. The flow meter can be linked to an alarm to remind the operator to replenish water.
Civil small-scale fluid measurement
Application scenarios: Water production measurement for household water purifiers (some desktop water purifiers use micro tipping bucket flow meters to count "filtered water volume" and remind filter replacement), flow monitoring for small hot water circulation systems (such as auxiliary flow measurement for household wall mounted boilers).
Core value: The micro tipping bucket flowmeter (with a volume only the size of a palm) can be integrated into civilian equipment, achieving low-cost "flow accumulation" function; For example, a water purifier can automatically remind users to replace the RO membrane by counting "filtered 500L of water", improving user convenience.
