The studies involve measuring flow of the cooling water, differential temperature across the tower, Enthalpy
of ambient and exhaust air, air flow rate as well as motor input power to assess operating performance of the
individual Cooling Tower.
The typical scope of the work covers
Measuring the flow of cooling water with non-contact ultrasonic transit time flow meter
Gauging temperature drop across the cooling tower with digital temperature indicator
Computing Heat Load on the cooling tower and delivered cooling effect
Determining fan Power with clamp on power meter
Noting down the ambient dry bulb and wet bulb temperature
Noting down the dry bulb and wet bulb temperature of the exhaust air
Measuring air flow rate to determine water to air ratio, if possible
Assessing the performance and suggesting ways for improvement, as applicable
Comparing the values with the design data to analyzing the gaps, if any.
Submitting the report
A team of two engineers is deputed to carry out the studies and furnishing the report. The field visit is
typically for 5 to 6 hours; during which up to 16 measurements can be carried out depending upon initial
preparations, type & conditions of units and support from the plant team.
