Water Metering

PYDRO's PT1 can be used for metering and data transfer even without the need of a power supply. It harvests energy from the water flow with a very low pressure drop. The meter data can be transferred via different communication protocols to the customer monitoring system.

Precise MeteringWithout Power Supply

Wireless Self-powered solution

Our System is independent from external power supplies as it harvests energy with its integrated hydro-power turbine and stores it in an internal battery.

Connected Device

Wireless real-time data transmission to any cloud-based or custom monitoring system via 3G, IoT or Mioty.

Multi-sensor Platform

Flow-, pressure- and temperature sensors are integrated. Additional sensors can be added.

Very Low Pressure Drop

The high performance runner and smart electronics keep the pressure losses at minimal levels.

Smart energy management

Energy consumption is constantly optimized based on battery charge level and flow conditions.

All-In-One Device

Integrated data logger, transmitter, battery and different communication options.

Robust Design

Very low maintenance. Only one moving part allows long-term reliability. Submersible in flooded chambers.

PYDRO Hardware Sensor Meter

The Hardware:
unique sensor systems


The integrated turbine is harvesting energy at point of use, making the PT1 system independent from external power supplies.

Multi-Sensor Platform

Pressure, flow and temperature sensors are integrated. Additional sensors can be added.

Wireless Transmission Module

The sensors‘ data is transmitted real-time to a cloud-based monitoring system.

The Dashboard

Have your water consumption and supply in permanent observation. Detect anomalies and make sudden rises in supply visible. The PT1 sends data 24/7 to the dashboard where data from different meters are aggregated. You can detect events on a map and react immediately.

Frequently Asked Questiones

For which pipe sizes is the PT1 used?

Currently the PT1 is developed for DN100 pipes, more versions come later. However, it can be used with adapters before and after the PT1.

What is the maximum pressure drop?

The pressure drop depends on the power generated in the turbine. We stop generating power at ca. 9 l/s and a pressure drop of 0,2 bar maximum.

Does it have drinking water certifications?

Yes, PT1 is currently under investigation of DVGW cert to get the German Water Certification to be used in drink water networks. We apply in other countries, too, if they do not accept the German certification.

For what pressure level is PT1 developed?

we tested the PT1 up to 16bar.

What is the protection level of PT1?

The PT1 has IP 68 to be installed in chambers which can be flooded.

Which protocol is PT1 using to send data?

At the moment we communicate via 3G, more LP1 communication standards will come.

Can you store the data internally, if the connection is lost?

Yes, the PT1 can store data up to 24 hours without losing measurements. After this time, old data will be overwritten by new measurements.

How long can PT1 measure and send data without water flow / power generation?

Under normal conditions, the internal Akku is loaded to 100% after 2-3 hours normal flow. With 100% battery the PT1 can measure and transmit data with reduces frequency up to 12 hours.

Does PT1 need maintenance?

Usually PT1 is maintenance free for a period of 10 years but this depends on real conditions.

Does the PT1 need calibration?

Calibration is needed according to country regulations if the data from PT1 is used to do billing. For water flow measurement there is usually no certification needed.

What is the maximum flow?

The maximum required flow in a DN100 pipe is ca. 27 l/s. We test our PT1 with a 25% overload.

What is the accuracy of flow measurement?

When working as a multi sensor, the accuracy is depending on your requirement and we do the settings. Maximum accuracy is up to +/-0,2%.

What class is the water meter?

If the PT1 works as a smart meter, we meet OIML class 1 standard (+/-2% in high flow and +/-5% in low flow area).
