3. Description
This manual is valid for the following device version
- Hardware from 2.0 and after
- Firmware from 2.1 and after
The Flow Data Logger FDL400 suitable for flow measurement in partially filled channels or
pipes.
The evaluation is performed according to the flow formula Q = VA.
A combined measuring sensor, mounted on the bottom or the wall of a channel detects the flow speed V
in m / s according to the Doppler principle. About a sound beam that shines against the flow direction in
the medium, the speed data is collected and further processed in the processor.
The integrated pressure sensor is used to detect the level in m;
above this value each perfused segment surface is again in the processor through a pre-programmed
channel cross section calculated in m2.
With the two multiplicands will calculated the sum Q in l / s.
The programming of all necessary parameters can made via 16 buttons on the front-panel keyboard.
The clear 4 lines display the individual values appear
- Velocity
- Level
- Flow
- Totalizer
The measuring sensor is powered from the FDL400 device with the necessary voltage. The two values for
flow rate and liquid level are directly on the sensor 4-20 mA signal is available. This allows the device to
be mounted further away from the location on your channel. Without any further installation work is
usually sufficient to cable extension of the probe.
