I. Core Application Industries and Scenarios

1. Municipal Water Supply and Drainage

• Pipeline Leakage Detection: By measuring the flow difference between the upstream and downstream of pipelines, it locates hidden leakage points in water supply networks (e.g., areas with abnormally increased flow), serving as a key tool for leakage control in smart water utilities.
• Water Quality/Water Pressure Supporting Detection: While sampling water quality and monitoring water pressure, it simultaneously measures flow to evaluate the water transmission efficiency of the pipeline network and the water supply guarantee capability at the terminal.
• Sewage Treatment Process Monitoring: Temporarily measures the inlet/outlet flow of water intake pump rooms, biochemical reaction tanks, and sedimentation tanks in sewage treatment plants to verify whether the operating load of sewage treatment equipment (such as aeration tanks and filters) matches the design value.
• Secondary Water Supply Acceptance: On-site verifies the actual water supply volume of secondary water supply equipment (e.g., constant-pressure water supply pumps) in residential communities to ensure it meets residents’ water demand.

2. Industrial Production Processes

• Equipment Performance Verification: Regularly calibrates the accuracy of fixed flow meters (such as electromagnetic flow meters and turbine flow meters) on production lines to avoid measurement deviations caused by equipment aging, thus ensuring the stability of processes like batching and transportation (e.g., raw material proportioning in the chemical industry, cooling water transportation in the power industry).
• Temporary Process Adjustment: When the production process changes (e.g., replacing raw materials, adjusting production capacity), it quickly measures the flow under different working conditions using portable equipment without modifying pipelines, providing data support for the optimization of process parameters.
• Fault Troubleshooting: When problems such as abnormal pressure or insufficient equipment output occur in the production line, it measures the flow of key pipelines (e.g., pump outlets, heat exchanger inlets and outlets) to determine whether insufficient flow is caused by pipeline blockage or pump failure.
• Energy Measurement Verification: Temporarily measures the flow of energy media such as industrial steam, circulating water, and compressed air, calculates the energy consumption of individual equipment, and assists in the formulation and effect evaluation of energy-saving renovation plans.

3. Heating, Ventilation, Air Conditioning (HVAC) and Heating

• Heating System Balance Commissioning: In the early stage of central heating, measures the flow of inlet supply/return water pipes of each building and unit, and adjusts valves to achieve uniform flow distribution, solving the problem of “overheating at the near end and cold at the far end”.
• Air Conditioning Water System Detection: Temporarily measures the flow of air conditioning chilled water and cooling water to determine the operating efficiency of water pumps and the heat exchange effect of heat exchangers (e.g., insufficient flow may lead to reduced cooling/heating capacity).
• Heating Measurement Verification: Verifies the flow accuracy of fixed heat meters (which calculate heat based on flow and temperature difference) between heating companies and users to avoid measurement disputes.

4. Petroleum, Chemical Industry and Natural Gas

• Pipeline Inspection and Maintenance: Conducts random flow checks on key nodes such as branch pipes of long-distance oil and gas pipelines and downstream of pressure reducing valves to monitor for problems such as illegal discharge, leakage, or blockage (portable ultrasonic flow meters suitable for gas media are required for natural gas pipelines).
• Tank Area Material Transportation Measurement: Quickly measures the transportation flow during temporary operations such as material loading/unloading and inter-tank material transfer, calculates the amount of material transferred, and replaces the temporary supplementary measurement of traditional manual weighing or fixed metering equipment.
• Corrosive Medium Measurement: For corrosive fluids such as strong acids, alkalis, and toxic substances, traditional contact flow meters are prone to corrosion. Portable ultrasonic flow meters measure through externally attached sensors, completely avoiding the risk of medium contact.

5. Power Industry

• Cooling Water System Monitoring: Equipment such as steam turbines and generators in thermal power plants and hydropower stations rely on cooling water for temperature reduction. By measuring the flow of cooling water pipelines, it ensures sufficient output of the cooling system and prevents equipment shutdown due to overheating.
• Boiler Feed Water/Steam Flow Calibration: Regularly calibrates fixed flow meters in boiler feed water pipelines, or temporarily measures steam flow after equipment maintenance to ensure that boiler operating parameters meet standards.

6. Agriculture and Water Conservancy

• Irrigation Flow Monitoring: During the farmland irrigation period, measures the flow of different irrigation canals and pipelines to optimize water resource allocation and improve irrigation efficiency (especially suitable for flow measurement in temporary irrigation areas).
• River/Reservoir Water Intake Measurement: Temporarily measures the flow of agricultural water intake ports and small reservoir spillways to assist in water resource scheduling and water consumption index assessment.

II. Typical Functional Applications

1. Calibration of Measuring Instruments: Serves as a “mobile standard meter” to conduct on-site comparison and calibration of fixed ultrasonic flow meters, electromagnetic flow meters, vortex flow meters, etc. in industrial, municipal, and other fields, without the need for equipment disassembly and without affecting production.
2. Temporary Flow Measurement: When fixed flow meters are under fault repair, new pipelines are not equipped with flow meters, or flow data is needed in short-term scenarios such as exhibitions/tests, portable equipment can be quickly put into use to meet emergency measurement needs.
3. Pipeline Condition Assessment: Judges whether there are problems such as pipeline scaling (gradual flow decrease), blockage (sudden flow drop), or valve abnormalities (unstable flow) by continuously measuring the fluctuation of pipeline flow.
4. Rotational Measurement Across Multiple Points: For scenarios requiring monitoring of multiple scattered measurement points (e.g., different workshops in large factories, multiple nodes in municipal pipe networks), one portable device can replace multiple fixed flow meters, reducing costs.

III. Summary of Application Advantages

• Production/transportation pipelines where fluid cannot be cut off;
• Pipelines with large diameters and high costs for installing fixed flow meters;
• Pipelines containing harsh media such as corrosive and turbid substances;
• Scenarios with mobility needs such as temporary detection, inspection, and calibration.
