Product Application
Cooling water, circulating water, critical water flow monitoring;
organic and inorganic solution flow monitoring;
freeze protection, spray system, sewage protection, etc.
Application in cooling water systems: Suitable for clean or lightly contaminated liquids with stable flow rates, ideal for vortex flow meter measurements. Commonly used in industrial cooling towers, heat exchangers, refrigeration units, etc., to monitor inlet/outlet water flow, ensuring cooling efficiency. Advantages: No moving parts, low maintenance costs.
Application in recirculating water systems: Suitable for long-term stable flow monitoring in recirculating water systems (such as central air conditioning, boiler feedwater). Provides high reliability. Applicable to closed or open recirculating systems, monitoring pump operation status or energy management. Advantages
