Level Measurement For Refrigeration, HVAC And Cooling Systems
Refrigeration, HVAC and cooling systems require reliable level measurement for chilled water tanks, cooling water tanks, condensate tanks, expansion tanks, cooling tower basins, thermal storage tanks, process cooling vessels and auxiliary water systems. SHAO provides level measurement solutions for pump protection, water level monitoring, overflow prevention, low-level alarm and stable cooling system operation.
Why Level Measurement Matters In Refrigeration And HVAC Systems
Cooling and HVAC systems depend on stable water circulation, pump protection and reliable tank level control. Low liquid level may cause pump dry running, unstable cooling, air entering the system or equipment shutdown. High level may cause overflow, water loss or poor system balance. A suitable level measurement solution helps operators maintain cooling efficiency, protect equipment and keep the system running safely.

Main Challenges In HVAC And Cooling Level Measurement
Refrigeration and HVAC systems often require stable level monitoring in water circulation, cooling, condensation and pump protection applications.
Cooling tower basins may have turbulence, foam and changing water level.
Chilled water tanks require stable continuous monitoring and pump protection.
Condensate tanks may experience frequent level changes during operation.
Outdoor cooling equipment may face humidity, dust and weather exposure.
Expansion tanks need reliable alarm signals for system safety.
Automation systems require stable 4-20mA, relay or RS485 output signals.

Frequently Asked Questions
What level sensor is suitable for chilled water tanks?
Pressure level transmitters or radar level meters can be used depending on tank size, installation position, temperature and output signal requirements.
Can level sensors be used for cooling tower basins?
Yes. Cooling tower basins may use radar, ultrasonic or pressure level sensors depending on basin structure, turbulence, foam and outdoor conditions.
Why is low-level alarm important in cooling systems?
Low level may cause pump dry running, cooling interruption, air entering the system or equipment shutdown. Low-level alarm helps protect the system before failure occurs.
Which solution is suitable for condensate tanks?
Condensate tanks may use pressure level transmitters, compact level sensors or level switches depending on tank size, temperature, pump control and alarm requirements.
