Ultrasonic level meters are widely used in various fields such as industry, municipal administration, environmental protection, food and medicine, thanks to their characteristics of non-contact measurement, strong adaptability, and simple operation. Here is a detailed introduction to their main application scopes:
1. Liquid Level Measurement in Industrial Storage Tanks and Containers
- Liquid storage tanks: Commonly used in various storage tanks in industries such as petroleum, chemical engineering, and metallurgy (e.g., crude oil tanks, acid-base storage tanks, solvent tanks, lubricating oil tanks) to monitor the real-time liquid level in the tanks, ensuring stable production processes or preventing overflow.
- Reactors and stirring tanks: In chemical reactors and stirring tanks in the pharmaceutical industry, they measure the liquid level of reaction media and cooperate with control systems to realize automatic feeding or discharging.
- Cooling circulation systems: Such as industrial cooling towers and circulating water pools, they monitor water levels to ensure the normal operation of cooling systems and prevent equipment overheating due to water shortage.
2. Municipal and Public Utilities
- Water treatment field: In clean water pools, sedimentation tanks of waterworks, regulating tanks and aeration tanks of sewage plants, they measure water levels to control water treatment processes (e.g., automatic regulation of water inflow and outflow).
- Urban pipe networks and pump stations: Used for liquid level monitoring in catchment wells of sewage pump stations and rainwater pump stations, realizing automatic start and stop of water pumps (e.g., starting drainage pumps when the liquid level reaches a threshold).
- Fire water pools and water tanks: Monitor the water levels of fire water pools and high-level water tanks to ensure sufficient fire water during fires and meet fire safety requirements.
3. Food and Pharmaceutical Industries
- Food processing: In scenarios such as raw material storage tanks (e.g., syrup tanks, edible oil tanks), cleaning tanks, and fermentation tanks in food production, non-contact measurement will not contaminate materials, meeting food hygiene standards (e.g., FDA, GMP requirements).
- Pharmaceutical production: Used for liquid level measurement in liquid medicine storage tanks, purified water storage tanks, and batching tanks, avoiding direct contact between sensors and liquid medicines to ensure drug purity and a clean production environment.
4. Environmental Protection and Agriculture
- Environmental monitoring: In landfill leachate treatment pools, waste liquid collection tanks, waste gas scrubbers, etc., they measure liquid levels to monitor the pollutant treatment process and prevent environmental pollution caused by leakage.
- Agricultural irrigation: Used for water level measurement in farmland reservoirs and irrigation canals, cooperating with intelligent irrigation systems to realize on-demand water supply and improve water resource utilization efficiency.
- Water conservancy monitoring: In water level monitoring stations of rivers, reservoirs, and lakes, they feed back water level data in real-time to provide a basis for decision-making in flood control and drought relief.
5. Warehousing and Logistics
- Silos and storage tanks: In grain storage silos, raw material silos of feed factories, cement silos in the building materials industry, etc., they measure solid material levels (e.g., powder, granular materials) to facilitate inventory management and material scheduling.
- Oil tankers and tankers: Used for liquid level monitoring in oil tankers and tankers during transportation to prevent overloading or leakage and ensure transportation safety.
6. Special Working Condition Scenarios
- Corrosive environments: Such as waste liquid tanks in electroplating workshops and acid-base storage tanks in chemical plants, non-contact measurement can prevent sensors from being corroded.
- High-viscosity or particle-containing media: Such as mud pools, paint tanks, starch storage tanks, measurement will not be affected by medium adhesion or wear.
Although widely used, ultrasonic level meters are greatly affected by the environment (e.g., strong dust, steam, violently fluctuating liquid surfaces). In such scenarios, it may be necessary to match waveguides, install anti-interference devices, or select special models (e.g., explosion-proof, high-temperature models) to ensure measurement accuracy.
In conclusion, as long as the surface of the measured medium can effectively reflect ultrasonic waves and environmental interference can be controlled, ultrasonic level meters can play an important role in liquid level/material level measurement and are commonly used equipment in industrial automation and process control.
