Description
The FDL400 "Flow Data Logger 400" measuring device is suitable for measuring the flow of water and wastewater in fully or partially filled sewers or pipes of various geometries.
Further product information
The evaluation is based on the flow formula Q = V x A.
Q = flow rate
V = flow velocity
A = wetted area
A combined measuring sensor mounted on the channel floor or wall records the flow velocity V in m/s according to the Doppler principle. The velocity data is recorded and processed in the processor via a sonic beam that radiates into the medium against the direction of flow. The integrated pressure sensor is used to record the fill level in metres; this value is in turn used in the processor to calculate the segment area in m² through which the flow passes according to a pre-programmed channel cross-section. The two multiplicands result in the sum Q in l/s
All required parameters are programmed using the 16-way keypad on the front of the device. The individual values appear in the clear 4-fold display

quantity
The measuring sensors are supplied with the necessary voltage by the evaluation electronics. In addition to its actual measuring function, the FDL400 measuring device also serves as a power supply unit for the approved sensors intended for this purpose. The device has 4 switching outputs.
Measurement data is stored on an SD card (Secure Digital Memory Card).
The device has a mini-USB interface (AB).
