What is the main purpose of thermometers on the inlet and outlet piping of a valve station?

The primary purpose of thermometers placed on the inlet and outlet piping of a valve station is to ensure accurate temperature control. Monitoring the temperature of the refrigerant or fluid at these key points allows operators to assess how much heat is being added or removed in a process, which is vital for maintaining the desired operational parameters of the system.

By comparing the temperatures at the inlet and outlet, technicians can evaluate the efficiency of the valve station and make necessary adjustments to the system. Accurate temperature readings also contribute to preventative maintenance, ensuring that the system operates within safe temperature ranges, ultimately promoting safety and efficiency.

Other options do not align with the direct function of thermometers in this context. Measuring flow rate typically involves flow meters rather than temperature readings. Monitoring structural integrity pertains more to the physical condition of the piping and equipment, which may require different types of monitoring devices. Calibrating the safety valve usually involves pressure measurements and other operational parameters rather than temperature alone.
