Product Applications
1. Petroleum industry
Application scenarios
Oil storage tanks: Used for inventory management, trade settlement and high and low liquid level alarm of crude oil and refined oil products (gasoline, diesel).
Wellhead device: Monitors the liquid level in the downhole or surface separator.
Oil pipelines and pumping stations: Monitor the liquid levels of dirty oil tanks and buffer tanks within the station.
Liquid level control in refining and chemical plants, such as atmospheric and vacuum distillation towers, reflux tanks, reactors, etc.
2. Chemical industry
Application scenarios
Raw material/product storage tanks: Store various acids, alkalis, solvents, and liquid chemical raw materials.
Reactor and synthesis tower: Control the liquid level during the reaction process to ensure the balance and safety of the chemical reaction.
Separation tank and distillation column: Precisely control the liquid interface to ensure separation effect.
3. Power Plants (Thermal/Nuclear)
Application scenarios
Deionized water tank/condensate water tank: Monitor the liquid level of boiler feed water.
Acid/alkali tank: Liquid level measurement of acid and alkali storage tanks in water treatment systems.
Condensate tank and expansion vessel: Collect and measure the condensate after the condensation of high-pressure steam.
Slag silos and ash silos: Although the medium is particles/slurry, they can also be used to measure the material level (special treatment is required).
4. Urban water supply
Application scenarios
Clear reservoirs/water storage tanks: Monitor the water storage capacity of urban water supply networks.
Pumping station: Controls the start and stop of water pumps to prevent dry running or overflow.
Water supply network pressure/liquid level monitoring points: Integrated into the network, they are used to monitor regional pressure and liquid levels in water towers/highland water tanks.
5. Hydrological Exploration and water Conservancy Engineering
Application scenarios
Automatic monitoring stations for river, lake and reservoir water levels.
Groundwater monitoring Wells: Long-term monitoring of dynamic changes in groundwater levels.
Flood season early warning system: Real-time monitoring of water levels in key water areas to provide data for flood control decision-making.
