Accurate flow measurement for drinking water, wastewater & industrial applications

  Evaporative cooling towers are key components in the effective operation of plants in the electric power, industrial process and manufacturing industries. They also are essential in the heating, ventilation and air conditioning (HVAC) systems that provide climate control in large facility complexes, such as educational and corporate campuses; casinos, hotels and convention facilities; data centres, and government, research and medical buildings. The proper control and treatment of cooling water is essential for efficient, safe and economical operations. Chemicals are fed to these systems that protect against fouling, corrosion and microbiological contamination. The proper dosage of these key chemicals is determined by having accurate information on the system make-up and blowdown water.
To achieve effective cooling through the cooling tower, it is necessary to maintain proper design flow through the cooling tower and thus provide adequate cooling of the system. Insufficient cooling water can affect critical equipment or building climate control. Accurate flow meters are the most effective tool to achieve reliable flow results and control system costs.
Here are three ways to optimise cooling water management with flow meters:Tip 1: Install a flow meter at the plant water intake source, which can turn the meters sub-meters. Comparing the flow data on all three lines helps identify potential water leaks and determine the system water balance plus other system issues.
Tip 2: Install flow meters upstream from pumps to provide flow data alerting the system to low flow situations leading to potential pump problems caused by low flow conditions. Otherwise, the result can be expensive pump repairs or even system shutdowns.
