Civil Engineering Measurement Equipment Water Level Gauge (Probe Type) NA-WF

Civil Engineering Measurement Equipment Water Level Gauge (Probe Type) NA-WF

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.

Submersible Water Level Gauge "HD Sensor Series"

Submersible Water Level Gauge "HD Sensor Series"

Manage data while measuring river and port water levels and tide levels with high precision!

The "HD Sensor Series" is a submersible water level gauge that can be widely used in harsh environments such as winter, extreme cold regions, tidal fluctuations, and drought conditions, as well as in rivers, estuaries, and ports. It protects the sensor detection part from seawater, barnacles, and other crustaceans, as well as from drought and freezing, using Delrin and a special oil, ensuring stable water level measurement. We offer a high-precision type "HD8300" with a two-wire system and an accuracy of 0.10% F.S., and a compact "HD8600" that uses a semiconductor pressure sensor for pressure detection. 【Features】 ■ Reliable design that withstands long-term use ■ Suitable for measurement in freshwater, brackish water, seawater, etc. ■ Equipped with a high-precision pressure sensor ■ Compact body design ■ Maintains measurement accuracy even in harsh environments ■ Can be installed in drought conditions or environments without water *For more details, please refer to the PDF document or feel free to contact us.

Risk Management Type Water Level Gauge Package proposed by Midori Engineering Research Institute

Risk Management Type Water Level Gauge Package proposed by Midori Engineering Research Institute

Compliant with the Ministry of Land, Infrastructure, Transport and Tourism specifications! Accurately grasp on-site conditions with images linked to water level and rainfall data during flooding.

The installation of water level gauges in small and medium-sized rivers faces the challenge of overcoming installation and maintenance costs. To address this, the Ministry of Land, Infrastructure, Transport and Tourism has developed water level gauges that focus on water level observation only during floods, reducing the size of the equipment and the costs of communication devices. At the Midori Engineering Research Institute, we propose a system that allows simultaneous viewing of water levels and still images by incorporating a camera, along with obtaining rainfall data, making it suitable for monitoring water-related disasters. It is expected that crisis management-type water level gauges will become widespread and be utilized for resident evacuations and flood predictions. 【Features】 ■ Linkage of water level, rainfall, and images ■ Visualization of data through our web monitoring system ■ Accurate understanding of on-site conditions with images linked to water level and rainfall data during flooding ■ Data storage and web application provision on a secure and stable cloud server *For more details, please refer to the PDF document or feel free to contact us.

Crisis management type water level gauge

Crisis management type water level gauge

Quickly predict river flooding due to heavy rain/typhoons! Notifications can be sent via email and other means based on your settings!

The product is a standalone water level gauge that continuously monitors and transmits measurements of water levels in rivers and ponds. It is designed to quickly predict flooding in rivers due to heavy rain or typhoons, aiding in evacuation guidance decisions. The "pressure detection type water level sensor" is installed by submerging the sensor part at the riverbed (or pond bottom) and measures the water level based on the water pressure when the water level rises. Additionally, it includes a "control box" that measures river water levels at 10-minute intervals, as well as components such as "solar panels" and "cloud servers." 【Overall Structure of the Device】 ■ Pressure Detection Type Water Level Sensor ■ Control Box ■ Solar Panel ■ Cloud Server ■ Client Terminal *For more details, please refer to the related links or feel free to contact us.

Small Absolute Pressure Water Level Gauge "S&DLmini Model-4900"

Small Absolute Pressure Water Level Gauge "S&DLmini Model-4900"

"Compact, lightweight, and inexpensive absolute pressure water level gauge" The body is coated with a special paint to enhance corrosion resistance! The battery life is designed for ultra energy efficiency, lasting up to 6 to 8 years.

The "S&DLmini Model-4900" is a compact, lightweight, and inexpensive absolute pressure water level gauge that incorporates a data logger and battery. By applying a special coating to the body (made of stainless steel), corrosion resistance is enhanced. Since it is an absolute pressure type without a vent tube, it is easy to handle, and we have successfully sealed the housing to prevent water ingress. 【Features】 ■ Compact, lightweight, and inexpensive ■ Ultra energy-efficient design with a battery life of up to 6 to 8 years ■ Easy setup by installing dedicated software on a PC ■ Improved communication connectivity and stability by changing the number of light reception points in the communication unit from 2 to 1 *For more details, please refer to the PDF materials or feel free to contact us.
