For tanker discharge, the WaterSam AutoSam provides a complete automated discharge and sampling system.
The system comprises:
- Driver Card reader & identification.
- Fluidics connections, mag flow meter,conductivity/pH sensors.
- Autosampler to take samples.
- Driver receipt identifying discharge parameters.
Controlling parameters can be set to halt out of spec. discharges.
Samples can be held and accumulated for laboratory testing in a refrigerated autosampler that can hold up to 35 samples. Each held discharge sample is a composite taken over the time of discharge.
Out of spec discharges can be diverted to a special holding tank.

In line screens can remove foreign bodies from the discharge load.
With irregular discharges such as tallow, the sample collection can programmed to take a sample at the start of discharge and completion of discharge to ensure there is no stratification within the load.
