OUR
SOLUTION

TAKUWA nurtured
Japan Quality Technology to the world

SOLUTION

Takuwa has studied the importance of knowing water from the river for half a century and has been making efforts to know the water. From this experience and accumulation we say "to know water and build good relationships with water" rather than to control the water is the only way to protect the lives of people from the threat of water and to coexist with that grace I arrived at the conclusion that should also be called the essence of being.
Takuwa thinks that only knowing the water seriously will protect people's lives from the threats of various disasters and enjoy the blessings of water. We have created various products by reflecting this feeling in knowledge and technology gained by facing water for many years.
We will not consider the water gauge as just a "observation device" to gather information, we will respond to the diverse needs of our customers and support future creation with our own one-stop solution.

WATER MEASUREMENT
PRODUCTS

Takuwa's water level observation technology, which has earned high recognition by high quality and thorough introduction and maintenance services, is a crystal of know-how and technology cultivated in the harsh natural environment of disaster-prone country Japan.
Failure to know the water, the observation device made easily, can not accurately measure the water level of the river in emergency, resulting in loss of many precious lives and property as a result. Takuwa is knowing the difficulty and importance of such water level observation from half a century of experience. And we will offer the highest water level observation technology reflecting experience and wisdom gained so far.

FLOOD CONTROL
SYSTEMS

Evolution from "to control water" to "to cuddle with water" - The answer that Japanese people have overcome over many years of difficulty is to solve the problem of the water environment confronted by the world now, to develop the development of each country and the global environment It has the potential to realize protection.
Takuwa's flood control and flood control solutions that embody such a spirit of Japan are more than just "flood prevention systems". We redefined the flood control and flood control from a macro perspective and fundamentally solve the various water and water control problems confronting each country after the 21st century and support a stable national development based on " It should be power.

WATER CONSERVATION
CONSULTING

The water level observation technology of Takuwa and the flood control and flood control know-how are not limited to the climate and the area, and have versatility that can be utilized in any region and country in the world. Furthermore, Takuwa will propose a comprehensive water environment model aiming at the improvement of the stability of the area, the living environment and the natural environment starting from the new form of waterproofing and flood control.
It is an unprecedented international support service that makes things necessary for the stability and growth of living and society starting from disaster prevention, helping town planning and the making of the world in the world.

WATER LEVEL OBSERVATION SYSTEM

Quartz Type Water Level Gauge
QS Series

Quartz type is a pressure type water level gauge by using Quartz oscillator which has high accuracy, high durability, and wide measuring range. It is suitable for accurate water level observation for river, irrigation, and dam.

Quartz Type Water Level Gauge(RS485)
QSM Series

It is a pressure-type sensor that measures the water level from the water pressure using a quartz oscillator. The frequency of the quartz oscillator is converted to the water level with high accuracy.
It allows you to output measurements as RS485 serial signals using commands.

Quartz Type Water Level Gauge
Optical Fiber Transmission type
OPQS Series

OPQS Series is, a kind of "Quartz pressure type", for enhancing the lightning protection. It using only optical fiber for cable of data transmission and electrical power supply by mounting the "very small optical-electric convertor" inside of the sensor.Recently in Japan, this type has been used for dam control and flood forecasting and warning systems.

Quartz Type Water Level Gauge
Water Temperature Correction type
QSR Series

QSR series is a Quartz type water level gauge which mounts temperature sensors along the cable. It corrects water level depending on water density by changing of water temperature and its distribution. Therefore, it can keep a high accuracy of water level measurement of large dam where seasonal variation of water temperature will occur.

Pressure-type Water Level Gauge
CPS Series

It is a pressure-type sensor that measures the water level from the water pressure using a ceramic resonator.
It outputs measurements in the form of DC signals at 4 to 20 mA.

Pressure-type Water Level Sensor(RS485)
CPS-R Series

It is a pressure-type sensor that measures the water level from the water pressure using a ceramic resonator.
It allows you to output measurements as RS485 serial signals using commands.

Laser Scanning type Water Level Gauge
LSW Series

It is a non-contact water level gauge. It measures the distance to the water surface by irradiating it with an infrared laser and monitoring the reflection.
The infrared laser scans the surface of water to get the reflection at multipoint.

Microwave Type Water Level Gauge
MIR-1 Series

Microwave Type Water Level Gauge that determines water level based on the pulse propagation time. As this equipment uses microwave, it is not influenced by environmental conditions such as temperature, and can provide a atable measurement in rivers, etc.
It outputs measurements in the form of DC signals at 4 to 20 mA.

Microwave Type Water Level Gauge(RS485)
MD-10 Series

This is a Microwave Type Water Level Gauge(RS485) that determines water level based on the pulse propagation time. As this equipment uses microwave, it is not influenced by environmental conditions such as temperature, and can provide a atable measurement in rivers, etc.
It allows you to output measurements as RS485 serial signals using commands.

Reed Switch Type Water Level Gauge
VM-10AS Series

It is a Reed switch Type Water Level Gauge equipped with a magnetic float and reed switches.
The float with a built-in permanent magnet moves up or down according to change in the water level, and it turns on the switch at a level in the gauge to sense the water level.

Signal Converter

It is a water level converter. It is connectible with a QSM Series, CPS-R Series water level sensor, or MD-10 Series water level gauge that supports RS485. It has water level conversion, calculation, digital display, and output functions. On its front panel, you can easily handle its settings. Its light and compact design allows easy implementation to, for example, control panel.

Color Staff Gauge
SG series

TAKUWA’s staff gauges have high visibility for manual water level observation with less reading error.

SEDIMENT DISASTER MONITORING AND DETECTION SYSTEM

Groundwater Aeration Sound Measuring Device
GAS-03

GAS-03 is a high sensitivity pick up sensor to hear Ground Aeration Sound (GAS) for detecting the position of groundwater pass. It can be useful for prediction of slope failure because existence of groundwater pass affects intensity to the slope. Also, it is possible to detect a leakage point of dam/dike body and so on.

Wire Sensor for Debris Flow Detection
GWD2 TYPE

Wire sensor is for detecting a debris flow directly by cut of a wire which is strung in the cross section of torrent. Detected signal can be output to the warning siren device for evacuation information.

Vibration Sensor for Debris Flow Detection
TSV TYPE

Vibration sensor is for detecting a debris flow indirectly and repeatedly by measuring a ground vibration. Usually sensor is buried in ground near the torrent.
Detected signal can be output to the warning siren device for evacuation information. In addition, it is possible to estimate discharge of debris flow by amplitude of vibration.

Warning Siren and Light
TWC-010 Series

Device that activates a Warning Siren and Light when receive an occurrence signal of debris flow from Wire sensor/Vibration sensor. It can be useful to quick evacuation for downstream residents.
