(29). Observe that the flow of water is indicated on the calibrated scale
adjacent to the inclined tube. Check the system for leaks.
17. Switch off the water pump, close all valves and open the well flow control
valves (32) to drain the sand tank (ensure that the ends of the flexible tubing
are located inside the sump tank. The equipment is now ready to be filled with
sand for experimental purposes. Refer to
Choice of Granular Material for the
Sand Tank for suggestions on suitable granular material for filling the sand
tank.
18. If the S12-MKII-50 version has been supplied then the following additional
actions will be necessary to ensure accurate measurement of water level
inside the collecting tank:
A plastic syringe with catheter attached is supplied for priming the connection
to the pressure sensor on the side of the collecting tank that is used to
measure the water level. Fill the plastic syringe with water then insert the
catheter through the tapping. Gradually inject water into the tapping and
withdraw the catheter until the tapping is completely filled with no air bubbles
present. It will be necessary to repeat this procedure after removing the tank
for emptying/cleaning etc.
When operating the equipment using the software ensure the level sensor is
zeroed in the software when the water level is coincident with the bottom of
the notch in the outlet weir.
