Application of flow switches and flow meters

Flow switch:

Industrial production: In various industrial manufacturing processes, flow switches can be used to monitor the flow of liquids (such as chemical raw materials, lubricants, etc.) or gases (such as compressed air, industrial gases, etc.) in pipelines. When the flow rate is lower or higher than the set value, the switch action is triggered to achieve the start stop control or alarm of the equipment, ensuring the safety and stability of the production process. For example, in automated production lines, ensuring a stable supply of materials; In the cooling system of some key equipment, prevent the coolant from flowing out.

HVAC system (heating, ventilation, and air conditioning system): used to monitor the flow of fluids such as chilled water and cooling water in the air conditioning system, ensuring the normal operation of the system. When the water flow is insufficient, the flow switch can send a signal in a timely manner to avoid damage to the air conditioning unit due to water shortage.

Water supply and drainage system: In urban water supply pipelines and building water supply and drainage pipelines, flow switches can be used to detect water flow status and achieve automatic control of water pumps. For example, when the incoming water flow of the municipal water supply network is insufficient, the water pump should be controlled to stop working to prevent damage caused by idling of the water pump; In the drainage system, the sewage discharge flow can be monitored and an alarm can be triggered in a timely manner in case of abnormalities.

Energy management: In energy transmission pipelines (such as natural gas pipelines and fuel pipelines), flow switches can be used to monitor the flow rate of energy transmission, provide data support for the rational allocation and use of energy, and take timely measures in case of abnormal flow to avoid energy waste and safety accidents.

Flowmeter:

Industrial process control: widely used in various industrial production processes, accurately measuring the flow rate of different media (such as liquids, gases, steam, etc.), providing accurate data basis for the optimization of production processes and quality control. For example, in the petrochemical industry, precise measurement of the flow rate of various raw materials and products is necessary to ensure the accuracy and stability of the production process; In the pharmaceutical industry, strict control of the flow of drugs is necessary to ensure the quality and consistency of the drugs.

Energy metering: used in the field of energy supply such as electricity, gas, and heat to measure the consumption of energy. For example, in gas companies, users’ gas usage is accurately measured through flow meters for billing and energy management; In thermal power plants, precise measurement of steam flow is carried out to evaluate energy output and consumption, and improve energy utilization efficiency.

Environmental protection: plays an important role in environmental protection fields such as sewage treatment and waste gas emission monitoring. Measure the flow rate of sewage to ensure the normal operation and treatment effectiveness of sewage treatment facilities; Monitor the flow rate of exhaust emissions to help companies control pollutant emissions and meet environmental standards. For example, in sewage treatment plants, the treatment process and equipment operating parameters are adjusted based on the data from flow meters; Install flow meters on the factory’s exhaust emission pipelines to monitor real-time exhaust emissions.

Transportation: In the aerospace field, it is used to measure the flow rate of aircraft fuel systems, engine intake systems, etc; In automobile manufacturing, flow measurement is used for engine fuel injection systems, cooling systems, etc. to optimize engine performance and fuel economy. For example, precise control of fuel injection quantity can improve the combustion efficiency of the engine, reduce fuel consumption and emissions.

Water conservancy engineering: used for monitoring water flow in rivers, channels, reservoirs, etc., providing data support for the rational scheduling of water resources, flood control and drought resistance decisions. For example, at hydrological stations, long-term monitoring of river flow changes through flow meters provides hydrological data for water conservancy departments; In large-scale water conservancy hub projects, the opening and closing of gates are controlled based on flow data to achieve scientific allocation of water resources.
