The level of development of technology equipment is assessed to be very feasible. At the beginning, when the new technology was completed, it was used for trial production, so far, the technology has been transferred by the manufacturing unit for industrial production and commercialized. .

Brief description of equipment technology : the system includes WLT water level probe, device that handles WLTD indicator and WaterView remote storage and control program running on personal computer (PC). Water level sensor WLT measures water changes and transmits information to storage devices and WLTD indicators. The PC has the ability to connect up to 31 indicator devices to form measuring networks.

The system can be conveniently used for remote measurement of water levels in reservoirs, settling tanks, filtration tanks of water plants, buildings or measuring water levels in irrigation canals and irrigation dams.

According to experts from the Institute of Information Technology, the successful fabrication of the automatic remote water level measurement system in the country has brought many economic and social benefits to the sectors, especially the fisheries sector. profit. Thanks to this system, it is easy to measure the water level in irrigation canals and irrigation dams so that there is a reasonable adjustment or irrigation plan from time to time.

In particular, the above equipment technology is designed and manufactured with high technology created by Vietnamese experts such as dedicated water level measuring chip, specialized processing and display chip, embedded software system and part Soft on PC WaterView of Vietnam, so it is easy to replace and upgrade as required by the actual application. Cost is only 70% of the cost of imported goods, which saves a considerable part of the cost.

Technical specifications of the system of automatic remote water level measurement: WLT measuring head consists of three types: 1 m, 2 m and 3 m; Resolution: 1 mm; continuous measurement by capacitor method; optimized head structure; dedicated measuring chip designed and manufactured by PsoC chip generation technology; digital processing and digital signal transmission according to RS485 standard (1.2 km); storage devices and WLTD indicators; receive and process the number of signals measured from the probe; Storage and 4 digit display; ability to calibrate measuring head in place; dedicated chip and indicator are designed and manufactured according to PsoC chip generation technology; pairing with PC via RS232 standard; WaterView program on PC; water level control at 31 different measurement points connected to a network; running on Windows 98/2000 / XP platform; capacity / capacity 12V / 0.6A.
