ultrasonic flowmeterMain application scenarios in the power industry

1. Circulating cooling water system

• Application scenariosThermal power plants, nuclear power plants, gas-fired power plants, etc. all require a large amount of circulating cooling water to remove heat from equipment such as turbines, condensers, and generators.
• Measurement requirementsMonitoring of cooling water flow for large-diameter (DN300 or above) pipelines.
• Advantage embodiment：
  • External clamp installation,No need to shut down, no need to cut pipesEspecially suitable for the renovation or addition of monitoring points in operating power plants.
  • Unobstructed flow component,No pressure lossIt does not affect the efficiency of the cooling system and is energy-saving.
  • Long term stable operation, suitable for continuous monitoring.

2. Supply water system

• Application scenariosFlow measurement of clean water such as boiler feedwater, desalinated water, and condensate water.
• Measurement requirementsHigh precision flow measurement, used for water balance analysis and efficiency calculation.
• Advantage embodiment：
  • Time difference method ultrasonic flowmeter is suitable forCleaning liquidHigh accuracy (up to ± 0.5%~1%).
  • Non contact measurement to avoid contaminating high-purity water quality.
  • It can be combined with temperature and pressure signals to achieve more accurate working condition compensation.

3. Condensed water recovery system

• Application scenariosSteam turbine condensate water recovery pipeline.
• Measurement requirementsMonitor the efficiency of condensate water recovery and evaluate the thermal efficiency of the system.
• Advantage embodiment：
  • Can adapt to high temperature water (requires selection of high temperature resistant sensors or thermal paste).
  • The bidirectional measurement function can determine whether there is backflow phenomenon.

4. Industrial fire water system

• Application scenariosFire water pipe network in areas such as large transformers, oil depots, and cable tunnels.
• Measurement requirementsMonitor for leaks on a regular basis and record instantaneous flow during a fire.
• Advantage embodiment：
  • Non invasive installation does not affect the sealing and safety of the fire protection system.
  • It can be monitored under pressure for a long time, and the system status can be grasped in real time.

5. Flue gas desulfurization (FGD) and environmental protection system

• Application scenariosLimestone slurry, process water, wastewater treatment, etc.
• Measurement requirementsMonitoring the flow rate of some slurry or sewage with low solid content.
• Precautions：
  • If the concentration of the slurry is too high or there are many bubbles, it is necessary to evaluate whether the time difference method is suitable; Otherwise, Doppler method or electromagnetic flowmeter can be considered.
  • External clamp installation avoids sensor corrosion and wear.

6. Heating, Ventilation and Air Conditioning (HVAC) and Auxiliary Systems

• Application scenariosThe chilled water and cooling water systems in the central control room, electronic equipment room, dormitory area, etc.
• Measurement requirementsEnergy consumption monitoring, cold and heat metering (in conjunction with temperature transmitters).
• Advantage embodiment：
  • Easy to install, suitable for building energy-saving renovation projects.
  • Supports signals such as Modbus and 4-20mA, making it easy to connect to energy management systems (EMS).

7. Performance testing and energy efficiency audit

• Application scenariosPerformance testing, thermal efficiency analysis, and water balance test after major overhaul of the unit.
• Measurement requirementsTemporary, high-precision flow measurement.
• Advantage embodiment：
  • Portable ultrasonic flowmeterCan be quickly deployed for multi-point measurement and data comparison.
  • It does not affect normal operation and can be removed or retained as a monitoring point after testing is completed.
