The WLMS is a monitoring equipment geared with ultrasonic sensors that measure the rate of water level. Ultrasonic sensors calculate time interval between sending the signal and receiving the echo to determine water level. Collected data are sent wirelessly, via cellular network, as a text message. Every WLMS has an ASTI-developed arQ, which serves as the mini-computer that intelligently controls all functions and data communications of the station. 

The Water Level Monitoring Station (WLMS) aims to aid with critical flood prone areas through flood monitoring and forecasting. The WLMS uses an ultrasonic sensor to measure the rate of change of water level. The sensor calculates the time interval between sending the signal and receiving the echo to determine the water level. The information collected is then transmitted to a central server at a predefined interval via SMS.



About Us

Over the years, the emergence of information and communications technology has greatly affected the lives of people in the world crossing borders among countries and bringing access closer to one another. In the same token, the birth of Microelectronics has resulted to progress in the development of smaller, lighter and more efficient electronic devices.

This development has a striking resemblance to the birth of one of the research and development institutes of the Department of Science and Technology (DOST) – the Advanced Science and Technology Institute (ASTI). It was in 1987 when President Corazon C. Aquino renamed the then National Science and Technology Authority (NSTA) to Department of Science and Technology (DOST). As an offshoot of such sequential events, the DOST-ASTI was created as a research and development institute of the Department by virtue of Executive Order No. 128.
