DB100 DL fire hydrant flowmeter with valve
The DB100 DL flowmeter is a professional measuring device designed for monitoring and checking fire hydrants. Fully digital, it enables precise measurement of water flow, pressure and volume during regulatory testing or maintenance operations.
Robust, autonomous and adapted to the most demanding field conditions, this fire hydrant controller is a reliable solution for network operators, local authorities and fire safety professionals.
How a flowmeter works
A flowmeter is a device used to measure the volume of fluid flowing through a pipe over a given period of time. In the case of the DB100 DL, measurement is based on a Woltmann-type turbine, renowned for its accuracy in high-flow hydraulic applications.
When water flows through the device, it causes the turbine to rotate. This rotation is converted into digital data, which is displayed in real time:
- Instantaneous flow rate (m³/h)
- Total volume flowed
- Network pressure
This principle guarantees reliable, reproducible measurement, essential for hydrant performance control and regulatory compliance.
