Cam Ranh International Airport in Central Vietnam welcomes more than 8.5 million passengers per year. The increasing number of travelers has made clear the need for proper management of both the water supply and the discharge of waste water into the surrounding environment. The most suitable solution involved the installation of an electromagnetic flowmeter and converter.
In addition to the supply of clean water, the management and controlled disposal of waste water (from parking areas, restaurants and kitchens, toilets, passenger terminals, aircraft refueling areas…) is also part of the airports’ sustainability objectives: the quantity and quality of wastewater must fall within the limits established by the sector’s environmental legislation in force.
ELECTROMAGNETIC FLOWMETERS
Electromagnetic flowmeters are a very good solution for measuring the flow rate of wastewater and in general of any liquid with a minimum conductivity of 5 µS/cm.
Characteristics:
- wide range of diameters available
- non-intrusiveness
- simplicity of operation
- high precision linear measurement flow rate
- non-influence due to physical parameters
- density
- temperature
- viscosity
- etc.
THE CHALLENGE
In Cam Ranh Airport there was a need to measure the amount of sewage by installing a two-way, electrically powered flowmeter inside a deep and narrow hole in the ground. The discharge capacity was 1000 m3/day.
THE SOLUTION
The solution for efficient water management at airports involved the use of our ISOMAG MS2500 sensor, DN150, IP68, combined with a line converter inserted in a stainless steel case.
- All meters of the ISOMAG line are calibrated on ISO17025-certified calibration benches. The original accuracy is guaranteed for the entire life of the meter if it operates in accordance with its technical characteristics.
- The IP68-rated device makes it possible to easily and reliably measure the volume of wastewater under difficult environmental conditions (the climate in Cam Ranh is warm all year round, with average temperatures of 30°C).
- The airport has the obligation to submit periodic reports to the environmental authorities. The accurate measurement of the wastewater flow rate provides essential data to prepare these reports, demonstrating compliance with environmental laws and standards.
- The data obtained were also useful for determining the operating costs associated with water management in the airport complex and for carrying out a more rigorous control of wastewater disposal costs and better investment planning.
