Online River Water Level Monitoring&Flood Warning by Radar Type River Water Level Transmitter
Radar Type River Water Level Transmitter is the non-contact type measuring instrument which shall be mounted above the river (no need to be submerged in the river water) and therefore no risks to be damaged by the river conditions, and furthermore, it provides stable measurement without any influence from the weather conditions because of the characteristic of electromagnetic wave principle. (see Fig. 1)
Fig. 1 Measuring principle of the level
Matsushima Measure Tech “MWLM series” with its high efficiency MIC (Microwave Integrated Circuit) and signal conditioning system realizes such stable continuous river water level monitoring even under typhoon, storm, heavy rain, etc.

Major Features and Advantages
- Stable monitoring under any severe weather conditions (no interference by wind and rain)
- Long lifetime because of the non-contact principle
- Real-time online monitoring and alert function depend on customer’s request
- Waterproof and dust proof (with cover)
- Connection with solar cell for off-grid operation
Product video (Japanese):
- Online real-time monitoring of river water level and issuance of flood warning
Our water level transmitter is securely and easily installed to bridges and other structures.
- Other various locations at dams, ponds, sewage works, etc. for water level monitoring
Fig. 4 Application of the level transmitter in various locations
- No risks of damage by river conditions because it can be mounted above the river (no need to be submerged in the river water)
- Long measurement range (max. 20m)
- Fine beam directivity (narrow beam angle 8deg.)
- No influence from weather conditions because the radar (electromagnetic wave) system never be affected by air conditions
For example, the reflection signal of Ultrasonic Level Transmitter damps around 30% under 10m/sec. velocity wind (damps over 40% under 20m/sec. wind) and the measurement becomes unstable, but Radar signal (electromagnetic wave) never be damped.
- Simple and easy commissioning and besides online remote adjustment possible
Please kindly refer to the table below. Warranty is N years.

Technical maturity / Past record of introduction
MWLM Series Radar River Water Level Transmitter is the state-of-the-art technology in the field of river water level monitoring. In Japan, 50 transmitters have been successfully installed to the domestic rivers: Kanda River, Mogami River, Odawara River, Tomita River, Kinzan River, Onga River, Chikuma River, etc.
All of them have been working (measuring real time river water level) continuously 24 hours 365 days a year without any fault.
【NETIS registered product】
The level transmitter has been registered to the New Technology Information System
(NETIS) operated by the government of the Ministry of Land, Infrastructure,
Transportation and Tourism, Japan.
