It observes the water level, converts it into an instrumentation current signal, and outputs it.
The contact-type water level gauge observes the water levels of rivers, lakes, groundwater, waterways, dam leakage, residual water, etc., and converts them into instrumentation current signals for output. The detector is suspended to the water surface by a single coated stainless steel wire and detects contact with the water surface by moving up and down with a motor. The detection signal corresponding to the water level change transmits the rotation of the measuring pulley through a relay circuit to the signal conversion section from the potentiometer, outputting an electrical signal (DC 4-20mA) as water level data. 【Features】 ○ Observes water levels and converts them into instrumentation current signals for output ○ The detector detects contact with the water surface by moving up and down with a motor ○ Sampling is possible within an interval timer operation of 10 seconds to 1 minute ○ Measurement range: 0 to 400 mm ○ Dimensions: φ300×285 mm, pulley diameter approximately φ160 mm For more details, please contact us or download the catalog.

Company information
Sokki Co., Ltd. was established in 1954 as the sales division of Sokki Sha Co., Ltd. (now Sokia Topcon). In 1962, it became independent in Hokkaido and began developing surveying instruments, responding to market needs for measurement technology in civil engineering measuring instruments, meteorological instruments, testing machines, and environmental and disaster prevention equipment. In particular, in the core business area of dam measurement, we provide long-life services that maintain and manage projects over a span of 10 to 20 years, from survey planning and design to construction and renewal. We also offer emergency response services during disasters such as landslides, rock collapses, earthquakes, and abnormal weather. Our offerings include not only hardware like surveying and measuring instruments but also software aspects covering planning, design, production, construction, and maintenance management. Furthermore, in the recent trend of information-based construction, we propose the latest various systems. For over half a century, we have continuously played a part in the development of social infrastructure from the field of surveying and measurement, which is a testament to the support we have received from our valued customers in various sectors. We will continue to strive to meet your measurement market needs, and we kindly ask for your continued support and guidance.
