LS520 Electronic static pressure liquid level sensor
Product Applications
1. Water treatment and environmental protection industry
Application scenarios
Waterworks/pumping stations: Liquid level monitoring and control of clear water reservoirs, water storage tanks and filter tanks.
Sewage treatment plant: Measurement of liquid level difference before and after the grid, monitoring of liquid level in aeration tank, sedimentation tank and sludge storage tank.
Pump control: Directly control the start and stop of submersible pumps or centrifugal pumps to prevent dry running (at low liquid level) and overflow (at high liquid level).
Water quality monitoring station: Integrated into online monitoring equipment (such as COD and ammonia nitrogen analyzers), it measures the liquid level of the sampled water sample.
2. Food, beverage and pharmaceutical industries
Application scenarios
Ingredient tank/mixing tank: Precisely control the liquid levels of water, syrup and raw materials to ensure formula consistency.
CIP/SIP system: Liquid level monitoring of cleaning solution and pure water/injection water storage tanks.
Fermentation tank: Monitor the fermentation liquid level.
Boilers and cooling systems: Liquid level control of softened water tanks and cooling tower water pools.
3. Industrial machinery and equipment (OEM matching)
Application scenarios
Cooling unit: Monitoring of water level in the cooling water tank and interlocking with the make-up water valve.
Machine tool: Liquid level monitoring of cutting fluid storage tank.
Air compressor/dryer: Monitor the liquid level of the condensate collection tank and control the drainage of the solenoid valve.
Hydraulic station: Real-time monitoring of the oil level in the hydraulic oil tank to prevent damage to the pump due to low oil level.
4. Building Automation and central Air Conditioning
Application scenarios
Water tanks/water towers: Liquid level monitoring and automatic water replenishment for domestic water tanks, fire water tanks, and expansion water tanks.
Boiler make-up water: Monitor the liquid level of the softened water tank and control the make-up water.
Sump: Monitor the liquid level in the basement sump and control the sewage pump.
5. Energy Management (Low-viscosity Oil Products
Application scenarios
Fuel oil boilers: Inventory management of diesel and heavy oil storage tanks.
Generator set: Monitoring of the fuel tank level of the standby diesel generator.
Gas station: Liquid level measurement of underground oil storage tanks (explosion-proof certification required).
