Venting
The GasClam has four venting modes, which can be selected in the Venting box (see below):
Always Closed – The vent is always closed
Always Open – The vent is always open.
Open once per day - The vent opens once a day
for a period of time defined by the user.
The vent opens open immediately after
the first sample and shuts after the allocated time.
Open after every – The vent opens and stays open for user defined periods.
If the GasClam is to be located in a wet area and the vent blank is installed tick the vent plug inserted box.
Water height
The GasClam can measure the water level in the borehole using an optional pressure transducer. To enable the water
level pressure transducer the „water level enabled‟ box in the Distance water height area needs to be ticked. The
GasClam reports the level in meters below ground level (mbgl) however, in order to calculate this distance 3 parameters
need to be entered; water density, water sensor length and the distance of the GasClam to the surface, see diagram
below. Pure water has a density of 1000 kg/m3 at 4°C. Borehole pressure affects the water level reading but this is
automatically corrected.
