Level Transmitter/Level Switch <Liquid>


Radar Type River Water Level Transmitter is a radio-controlled level meter that continuously measures the water level of rivers, dams, tide levels, factories, agricultural water, regulating reservoirs, sluice gates, water treatment facilities, reservoirs, erosion control, etc.


  1. Stable measurement is possible without being affected by storms, turbid currents, sedimentary mud and sand, changes in flow speed, etc.
  2. When used as a crisis management type water level transmitter, there is no need to worry about being swept away by muddy water because it is a non-contact measurement.
  3. Maintenance is easy with no consumables .

Features of Radar Type River Water Level

The main features of Radar Type River Water Level Transmitter are as follows.

Reliable Radio Law
Compliant Product

It is a weak wireless compatible device that uses 26 GHz radio waves (microwaves) and suppresses the electric field strength . It does not require a handling license and can be used safely even in open spaces.

Up to 20m can be measured.

It can be used in rivers, sewage treatment pumping stations, relay pumping stations, water purification facility filtration ponds, etc.

NETIS registered product

NETIS is a new technology information provision system that the Ministry of Land, Infrastructure, Transport and Tourism is working on. We solve various problems currently facing public works, support companies with excellent technology, and promote further new technology development. It is registered with the following contents.

・New technology name: Stability measurement radio wave level meter
・NETIS registration number: QS-200062-A

Equipped with
HART communication

Adjustments can also be made with devices that support HART communication.

Operating principle

Radar Type River Water Level Transmitter is a time flight type (TOF) radio level meter that uses a frequency of 26 GHz (microwave).

What is the time flight method (TOF)?
Radio waves (microwave pulses) emitted from the sensor are reflected on the surface of the object to be measured, and are received by the sensor again as reflected waves. This method converts the round-trip time of this radio wave (microwave pulse) into a distance and measures it.

How to use?

mounting position

Choose a position that does not allow any obstacles to enter the measurement area of ​​the level transmitter or that the object to be measured does not enter the dead zone of the level transmitter. If you have any concerns about the mounting position, please contact us.

2. Mounting

Install the level transmitter so that the transmission direction of the level transmitter is as vertical as possible to the measurement surface (liquid level).

3. Wiring

Power supply and analog output can be performed with two wires because of the two-wire transmission method. Please connect with our Signal Conditioner or a commercially available distributor. Measurement starts when the power is turned on.

4. Adjustment

By connecting a notebook PC with dedicated software to a level transmitter using a dedicated cable, you can easily set 0% and 100%, learn noise, and check waveforms.

*For details, please refer to the instruction manual.

for level transmitter
Signal Conditioner

Signal Conditioner is a converter compatible with 2-wire transmission type sensors and also supports HART communication. It also has a display function, so you can monitor the measured value of the level meter from a remote location. In addition, it is equipped with analog output and alarm contact output, making it a versatile device.
