Used for water level measurement for flow calculations using JIS-compliant wells and partial flumes.
The "WW4483" is a two-wire transmitter that measures changes in water depth using a semiconductor pressure sensor and converts it into a 4-20mA DC current signal. Using an external air pressure introduction tube built into a dedicated cable, it introduces external air pressure to the transmitter and corrects measurement errors caused by fluctuations in external air pressure. It can be used for water level measurement to calculate flow rates using "weirs" or "partial flumes." 【Features】 ■ Easy maintenance on-site ■ Built-in lightning protection ■ Flow calculations performed by dedicated converter WW4486 *For more details, please download the PDF or feel free to contact us.

Company information
YDK Technologies contributes to a peaceful and prosperous society by supporting your safe and secure living through advanced and diverse sensing technologies in four fields: defense, environmental measurement, navigation, and aviation/combustion, on a global scale. What is common among these efforts is the commitment to "play a part in creating a society where people can live with peace of mind by providing reliable devices and information." The environmental measurement business was founded in 1852 as Nakamura Sakyoshi Surveying Instruments, and after several name changes to Nakasa Instruments, Yokogawa Weatherc, Yokogawa Electronic Devices, and YDK Technologies, we have been engaged in the development, manufacturing, and sales of meteorological and hydrological observation instruments. We will continue to fulfill this social mission while looking to the future and challenging ourselves in new fields using innovative technologies.
